Detailed Description

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The extending direction of the central axis C of the motor 1 shown in fig. 1 is simply referred to as an "axial direction", and the radial direction and the circumferential direction around the central axis C of the motor 1 are simply referred to as a "radial direction" and a "circumferential direction". The terms "axial", "radial", and "circumferential" are used for the purpose of description, and do not limit the actual positional relationship or direction. In the present embodiment, for convenience of explanation, the shape and positional relationship of each portion will be explained by assuming that the axial direction is the up-down direction and assuming that the up-down direction in fig. 1 is the up-down direction of the motor 1.

However, the vertical direction is not intended to limit the orientation of the motor 1 of the present invention in use.

< 1. Structure of Motor >

A motor of an exemplary embodiment of the present invention will now be described. Fig. 1 is a longitudinal sectional perspective view of a motor 1 according to an embodiment of the present invention.

The motor 1 includes a rotor 20, a stator 30, an upper bearing (bearing) 41, a lower bearing 42, a housing 50, a terminal block 60, and a rotation detector 92.

2-1 Structure of housing

The housing 50 houses the rotor 20, the stator 30, the upper bearing 41, and the lower bearing 42. The housing 50 has a peripheral wall portion 51, a bottom wall portion 52, and an upper wall portion (lid wall portion) 53.

The peripheral wall 51 is formed in a cylindrical shape extending in the axial direction. The upper surface and the lower surface of the peripheral wall 51 are open. The lower surface of the peripheral wall portion 51 is covered with a bottom wall portion 52. The upper surface of the peripheral wall portion 51 is covered with an upper wall portion 53. That is, the upper wall portion (cover wall portion) 53 covers the upper surface (one end surface in the axial direction) of the peripheral wall portion.

The bottom wall portion 52 has a lower bearing holding portion 52a. The lower bearing holding portion 52a is formed in a cylindrical shape surrounding the central axis C. The lower bearing 42 is received and held in the lower bearing holding portion 52a.

The upper wall portion 53 includes an upper bearing holding portion 53a, an upper wall through hole (lid wall through hole) 53b, an upper wall screw hole 53c, a side wall portion 53d, and an upper tube portion 53e. The upper bearing holding portion 53a is formed in a cylindrical shape surrounding the central axis C. The upper bearing 41 is received and held in the upper bearing holding portion 53 a.

The upper wall through hole 53b is arranged radially outside the upper bearing holding portion 53a, and penetrates the upper wall portion 53 in the axial direction. The lead wire 33a described later is inserted into the upper wall through hole 53 b. The upper wall screw hole 53c is provided at 4 places around the upper bearing holding portion 53a (see fig. 3). The terminal block 60 is screwed to the upper surface of the upper wall portion 53 via an upper wall screw hole 53 c.

The side wall 53d protrudes axially upward from the upper surface of the upper wall 53 and is formed in a tubular shape. The side wall portion 53d surrounds the terminal block 60. The upper surface of the side wall portion 53d is opened and covered with a cover 54. The side wall portion 53d has side wall through holes 53f (see fig. 2 and 4) arranged at three positions. The sidewall penetration hole 53f penetrates the sidewall portion 53d in the radial direction. The external terminal 90 is introduced into the side wall portion 53d through the side wall through hole 53 f.

The side wall portion 53d is provided with a side wall through hole 53g (see fig. 2 and 3) at one position. The sidewall penetration hole 53g penetrates the sidewall portion 53d in the radial direction. The bundling signal wire 73 described later is led out of the case 50 through the side wall penetrating hole 53 g.

The upper tube portion 53e surrounds the central axis C, and extends axially upward from the upper surface of the upper wall portion 53 to form a cylindrical shape. The upper tube portion 53e is internally provided with a rotation detector 92 described later. The upper cylindrical portion 53e and the upper bearing holding portion 53a communicate in the axial direction.

< 3. Structure of rotor >

Rotor 20 includes a shaft 21, a rotor core 22, and a rotor magnet 23. The shaft 21 forms a rotation axis extending along the central axis C, and is formed in a columnar shape. That is, the rotor 20 has a shaft 21 extending along the rotation axis. The shaft 21 is supported rotatably about an axis by an upper bearing 41 and a lower bearing 42.

The lower end portion of the shaft 21 protrudes outside the bottom wall portion 52 via the lower bearing holding portion 52a. The upper end of the shaft 21 is disposed inside the upper tube 53e.

The rotor core 22 is formed in a cylindrical shape, and the shaft 21 is fixed by press-fitting inside. The rotor magnet 23 is provided on the radially outer surface of the rotor core 22, and a plurality thereof are arranged in the circumferential direction. The rotor core 22 and the rotor magnet 23 rotate integrally with the shaft 21.

< 4. Structure of stator >

The stator 30 is disposed radially outward of the rotor 20. That is, the stator 30 and the rotor 20 are opposed to each other with a gap therebetween in the radial direction. The stator 30 is formed in a cylindrical shape, and the rotor 20 is disposed inside the stator 30. The stator 30 includes a core back 31, pole tooth portions 32, coils 33, and an insulating member (not shown).

The core back 31 is formed in a cylindrical shape concentric with the shaft 21. The outer peripheral surface of core back 31, that is, the outer peripheral surface of stator 30 is fitted to the inner peripheral surface of peripheral wall 51 of case 50. That is, the peripheral wall 51 is formed in a cylindrical shape covering the stator 30 from the radial direction.

The tooth portions 32 extend radially inward from the inner peripheral surface of the core back 31. The plurality of pole teeth 32 are provided and are arranged at equal intervals in the circumferential direction of the inner circumferential surface of the core back 31.

The coil 33 is formed by winding a lead wire 33a around an insulating member (not shown). The coil 33 corresponds to a plurality of U-, V-, and W-phases. That is, the stator 30 has a plurality of phase coils 33. An insulating member is mounted on each tooth 32. The end portion of the lead wire 33a wound around each tooth portion 32 extends upward in the axial direction, is led out to the upper side in the axial direction of the upper wall portion 53 through each upper wall through hole 53b, and is connected to the connection portion 61 of the terminal block 60. The connection structure of the wire 33a will be described in detail later.

When a driving current is supplied to the coil 33, a magnetic field is generated, and the rotor 20 rotates due to the magnetic field.

< 5 sensor magnet Structure >

The sensor magnet 91 is an annular permanent magnet, and its N-pole and S-pole are alternately arranged in the circumferential direction. The sensor magnet 91 is fitted to the upper end of the shaft 21. Thereby, the sensor magnet 91 is arranged to be rotatable together with the shaft 21.

< 6. Structure of rotation detector >

In the present embodiment, the rotation detector 92 is fixed inside the upper tube portion 53e. The rotation detector 92 is axially opposed to the sensor magnet 91 with a gap therebetween. The rotation detector 92 detects the magnetic flux of the sensor magnet 91 to detect the rotational position of the rotor 20. Thereby, a motor drive signal corresponding to the rotational position of the rotor 20 is output, and the drive current supplied to the coil 33 is controlled. Thus, the driving of the motor 1 can be controlled.

< 7. Structure of terminal block >

The terminal block 60 is a plate-shaped resin molded product, and is disposed on the upper surface (one end surface in the axial direction) of the upper wall portion (cover wall portion) 53 and fixed to the housing 50. The lead wire 33a and the external terminal 90 are fixed to the terminal block 60. The terminal block 60 is disposed on an axial upper side (axial side) of the housing 50, and at least a part of the terminal block 60 overlaps with the upper bearing 41 (bearing) in the axial direction. This prevents the lead wire 33a from being wound radially outward of the housing 50, and the motor 1 can be miniaturized in the radial direction.

< 8. Connection structure of wire and external terminal >)

Fig. 2 to 4 are perspective views of the motor 1, and the cover 54 is not shown. Fig. 2 shows the external terminal 90 by a chain line. Fig. 3 does not show the terminal block 60 and the lead wire 33a. Fig. 4 shows the connecting screw 61a in an exploded manner.

The ends of the wires 33a corresponding to the U-phase, V-phase, and W-phase coils 33 extend axially upward from the coils 33, and are led out axially upward of the upper wall 53 through the upper wall through holes 53 b. In addition, the lead wire 33a is bent in the radial direction and extends along the upper surface of the terminal block 60. In addition, the lead wire 33a is covered with an insulating member on the axial upper side of the coil 33.

The lead wire 33a has a connection terminal 33c (see fig. 4) disposed at the tip end. The connection terminal 33c has a terminal through hole 33d. The terminal through hole 33d is axially overlapped with a terminal block screw hole 61b (see fig. 5) provided in the terminal block 60, and is screwed by a connecting screw 61a. At this time, one end of the external terminal 90 is clamped between the connection screw 61a and the connection terminal 33 c. Thereby, the lead wire 33a and the external terminal 90 are fixed to the terminal block 60. Accordingly, the lead wire 33a is electrically connected to the external terminal 90, and a motor drive signal is output from the external terminal 90 to the lead wire 33a.

At this time, the terminal block screw hole 61b constitutes the connection portion 61 of the terminal block 60. That is, the terminal block 60 has a connection portion 61 for connecting the lead wire 33a to the external terminal 90. The lead wire 33a has a bent portion 33b which is led out from the coil 33 to the upper side (axial side) in the axial direction and is bent toward the connection portion 61 in a direction orthogonal to the axial direction.

The connecting portion 61 and the curved portion 33b are disposed on opposite sides with respect to a center line L extending in the radial direction through the rotation axis C as viewed in the axial direction (see fig. 2). Thus, the connection portion 61 and the bent portion 33b can be arranged separately on the terminal block 60, and the length of the wire 33a from the bent portion 33b to the connection portion 61 can be made longer. Therefore, when the lead wire 33a and the external terminal 90 are connected, the handling of the lead wire 33a becomes easy. This improves the workability of assembling the motor 1. In addition, during the assembly operation of the motor 1, the load applied to the bent portion 33b can be reduced, and the breakage of the lead wire 33a can be prevented.

The conductors 33a of the plurality of phases extend in parallel in a straight line from the bent portions 33b toward the connection portions 61 on the terminal block 60. Thus, when connecting the wires 33a and the external terminals 90, the handling of the plurality of wires 33a becomes easier. In addition, the terminal block 60 can prevent the leads 33a from crossing each other and being broken.

< 9. Structure of terminal block >

Fig. 5 and 6 are perspective views of the terminal block 60. Fig. 5 shows the terminal block 60 from the axial upper side, and fig. 6 shows the terminal block 60 from the axial lower side. The terminal block 60 has a connection portion 61, partition walls 621, 622, a terminal block through hole (through hole) 63, a fixing portion 64, a fixing partition portion 65, a rib 66, a terminal block recess 67, and an inclined portion 68.

The connection portion 61 connects the lead wire 33a to the external terminal 90 and fixes the lead wire to the terminal block 60. The connection portion 61 has a terminal block screw hole 61b. The terminal block screw hole 61b overlaps the terminal through hole 33d in the axial direction, and is screwed via the connection screw 61a. In the present embodiment, the lead wire 33a is connected to the external terminal 90 by using the connection screw 61a and the terminal block screw hole 61b, but may be connected by soldering or the like.

The partition walls 621, 622 protrude from the upper surface (end surface on the axial side) of the terminal block 60 toward the axial upper side (axial side). The partition wall 621 is disposed between the adjacent wires 33a. By providing the partition wall 621, the adjacent wires 33a can be prevented from contacting each other. In addition, the insulation distance between the adjacent wires 33a can be ensured.

The partition walls 622 are disposed in a pair at both ends of the terminal block 60 in the parallel direction of the wires 33a. In addition, the partition wall 622 extends parallel to the extending direction from the bent portion 33b of the wire 33a to the connection portion 61, as viewed from the axial direction. The partition wall 622 is disposed between the side wall portion 53d and the wire 33a. By providing the partition wall 622, the wire 33a can be prevented from contacting the side wall portion 53d. In addition, the insulation distance between the wire 33a and the side wall 53d can be ensured.

The partition wall 621 has a partition concave portion 621a and a pressing portion 621b. The partition concave portion 621a is recessed from the upper surface (end surface on one side in the axial direction) of the partition wall 621 toward the lower side in the axial direction (the other side in the axial direction). By providing the partition concave portion 621a, the weight of the terminal block 60 can be reduced.

The pressing portion 621b protrudes from the outer periphery of the partition wall 621 in a direction orthogonal to the axial direction, covering the axial upper side (axial side) of the lead wire 33a. By providing the pressing portion 621b, the lead wire 33a can be prevented from falling off the terminal block 60.

The terminal block through hole (through hole) 63 axially penetrates the terminal block 60 and axially overlaps the pressing portion 621b. By providing the terminal block through-hole 63, the upper surface of the upper wall portion 53 can be visually inspected from the terminal block through-hole 63 when the terminal block 60 is disposed on the upper wall portion 53. Thus, for example, by providing the positioning pin or the like on the upper surface of the upper wall portion 53, the positioning of the terminal block 60 can be easily performed while checking the positioning pin through the terminal block through hole 63. Therefore, the assembling workability of the motor 1 is further improved.

The fixing portion 64 is disposed between the adjacent wires 33a, and fixes the terminal block 60 to the housing 50. In the present embodiment, the fixing portion 64 has a fixing screw hole 64b. The fixing screw hole 64b is formed to penetrate the terminal block 60 in the axial direction. The fixing screw hole 64b axially overlaps the upper wall screw hole 53c, and is screwed by the fixing screw 64 a. Thereby, the terminal block 60 is fixed to the upper wall 53.

The fixing spacer 65 is disposed between the lead wire 33a and the fixing portion 64 so as to protrude from the periphery of the fixing portion 64 to the upper side in the axial direction (axial direction side) on the upper surface (axial direction side end surface) of the terminal block 60. In the present embodiment, the fixed partition portion 65 is formed in a U-shape as viewed from the axial direction. By providing the fixing partition portion 65, the fixing portion 64 can be prevented from contacting the wire 33a. In addition, the insulation distance between the fixing portion 64 and the wire 33a can be ensured. The fixed partition 65 may be formed continuously with the partition wall 621.

In the present embodiment, the fixed partition portion 65 is formed to protrude from the upper surface of the terminal block 60, but may be formed to be recessed from the upper surface of the terminal block 60 toward the other side in the axial direction. That is, the fixed partition portion 65 may extend in the axial direction from the upper surface (end surface on one axial side) of the terminal block 60 between the lead wire 33a and the fixed portion 64.

In addition, at least a part of the bent portion 33b and the fixing portion 64 overlap in a direction orthogonal to an extending direction in which the wire 33a extends from the bent portion 33b toward the connecting portion 61, as viewed from the axial direction. Thereby, the curved portion 33b can be disposed adjacent to the fixing portion 64. Therefore, when the lead wire 33a is brought into contact with the terminal block 60 to form the bent portion 33b, the terminal block 60 can be prevented from rocking with respect to the housing 50.

The rib 66 protrudes from the lower surface (end surface on the other axial side) of the terminal block 60 toward the lower axial side (the other axial side). The rib 66 extends from the fixing portion 64 toward the connecting portion 61. This can suppress deformation of the terminal block 60.

The terminal block concave portion 67 is formed by the outer edge portion of the terminal block 60 being recessed inward when viewed in the axial direction. The lead wire 33a is disposed inside the terminal block recess 67. This can prevent the lead wire 33a from protruding radially outward from the side surface of the terminal block 60. Therefore, the radial dimension of the side wall portion 53d does not need to be formed large. This can further suppress the motor 1 from becoming larger in the radial direction. Further, since the lead wire 33a is disposed in the gap between the terminal block concave portion 67 and the side wall portion 53d, positioning of the lead wire 33a becomes easy, and workability is further improved when the lead wire 33a is led and connected to the connection portion 61.

The inclined portion 68 is inclined axially downward (axially on the other side) toward the radially outer side at the outer edge portion of the terminal block 60. The curved portion 33b is arranged on the inclined portion 68. As a result, the bent portion 33b is less likely to be broken by contact with the inclined portion 68 than by contact with the outer end portion of the terminal block 60 where the inclined portion 68 is not formed. Therefore, by bending the lead wire 33a along the inclined portion 68, breakage of the lead wire 33a can be prevented.

The rotation detector 92 is disposed in an axial gap between the housing 50 and the terminal block 60, and the first signal line 71 connected to the rotation detector 92 extends in a direction perpendicular to the axial direction through the gap between the housing 50 and the terminal block 60 (see fig. 3). Thus, the signal line connected to the rotation detector 92 and the lead wire 33a are disposed so as to be separated from each other in the axial direction via the terminal block 60. Accordingly, the insulation distance between the signal line connected to the rotation detector 92 and the wire 33a can be ensured.

The second signal line 72 connected to a thermistor (not shown) for detecting the temperature of the coil 33 of the stator 30 also extends in the radial direction through a gap between the housing 50 and the terminal block 60 (see fig. 3). Thereby, the insulation distance between the second signal line 72 connected to the thermistor and the lead wire 33a can be ensured. The thermistor is not limited to the case of detecting the temperature of the coil 33, and may detect the temperature of the rotor magnet 23 or the case 50.

The second signal line 72 extends from the thermistor to the upper side in the axial direction, and is led out to the upper side in the axial direction of the upper wall portion 53 through the upper wall through hole (lid wall through hole) 53 b. The second signal line 72 passes through the upper wall through-hole 53b as in the case of the lead wire 33a, and the upper wall 53 does not need to be newly formed with a through-hole. Therefore, the manufacturing cost of the housing 50 can be reduced. In addition, by drawing the lead wire 33a and the second signal wire 72 from the same upper wall through hole 53b, the handling of the lead wire 33a and the second signal wire 72 is facilitated, and the assembling workability of the motor 1 is improved.

The first signal line 71 and the second signal line 72 are bundled by, for example, a connector to form a bundled signal line 73. The strapping signal line 73 is led out of the case 50 through the sidewall through hole 53 g. That is, the first signal line 71 and the second signal line 72 are bundled and led out to the outside of the housing 50. This facilitates the processing of the first signal line 71 and the second signal line 72, and improves the workability of assembling the motor 1.

The above-described embodiments are merely examples of the present invention. The configuration of the embodiment may be changed as appropriate within a range not departing from the technical idea of the present invention. Further, the embodiment and the plurality of modifications may be implemented in combination as far as possible.

Industrial applicability

The motor of the present invention can be used in an electric power steering device for assisting steering operation of a vehicle such as an automobile. The present invention is applicable to, for example, a power steering device, but may be applied to other blower devices and the like.
