Description
Technical field
The utility model belongs to technical field of motors, and in particular to a kind of rotor pole knot of novel switched reluctance motor
Structure.
Background technology
For switch reluctance machine rotor without the structures such as winding and slip ring, stator winding end is shorter, thus it is simple in structure, simultaneously
The control and driving of switched reluctance machines are simple, and reliability is higher.And two-phase switched reluctance machines are the less one kind of the number of phases opens
Close reluctance motor, structure is comparatively simpler, and motor and controller are at low cost, and connecting line is few, and slot space is big, for reduce around
Group copper loss is provided convenience, and the workplace of high speed or bad environments is suitable for.But traditional two-phase switched reluctance machines have
Torque dead-band causes it not have self-startup ability, since the number of phases is less and there is " torque dead-band ", the more motor with the number of phases
It compares, the pulsation that two-phase switched reluctance machines synthesize torque is also larger.
Invention content
The utility model is intended to provide a kind of rotor pole structure of novel switched reluctance motor, is opened with solving traditional two-phase
Pass reluctance motor vibration noise is larger and there are problems that " torque dead-band ", non self starting, and improves motor torque characteristic,
Improve output power and transmission efficiency.
The technical solution used by the utility model is in order to achieve the above objectives：Including stator poles, rotor pole and aluminum
Conducting surface, it is the rank of noncontinuity that the stator poles, which use oblique pole structure, 15 degree of angles of Off-Radial, the rotor pole surfaces,
Ladder configuration, two rotor poles are symmetrical, and the aluminum conducting surface is arc-shaped, is placed on outside rotor pole body.
In above-mentioned technical proposal, described 15 degree of angles of stator poles Off-Radial straight line.
In above-mentioned technical proposal, the rotor pole surfaces are discrete ladder-like.
In above-mentioned technical proposal, the arc-shaped aluminum conducting surface is placed on outside rotor pole body.
By using above-mentioned technical proposal, what is provided has the advantages that：Stator poles use oblique pole structure, Off-Radial
15 degree of angles make radial electromagnetic force suffered by motor stator evenly, help to reduce torque ripple, reduce the vibration of motor and make an uproar
Sound, rotor pole surfaces are the step structure of noncontinuity, motor in any position can self-starting, eliminate that " torque is dead
Area ", aluminum conducting surface are arc-shaped, are placed on outside rotor pole body, can improve the torque characteristics of motor, improve output power with
And transmission efficiency.

The aluminum conducting surface is arc-shaped, is placed on outside rotor pole body.
By using above-mentioned technical proposal, what is provided has the advantages that：Stator poles use oblique pole structure, Off-Radial
15 degree of angles make radial electromagnetic force suffered by motor stator evenly, help to reduce torque ripple, reduce the vibration of motor and make an uproar
Sound, rotor pole surfaces are the step structure of noncontinuity, motor in any position can self-starting, eliminate that " torque is dead
Area ", aluminum conducting surface are arc-shaped, are placed on outside rotor pole body, can improve the torque characteristics of motor, improve output power with
And transmission efficiency.
Stator poles are circumferentially evenly distributed in stator yoke inner surface, and stator poles use oblique pole structure, Off-Radial straight line
15 degree of angles make radial electromagnetic force suffered by motor stator evenly, help to reduce torque ripple, reduce the vibration of motor and make an uproar
Sound, rotor pole surfaces be noncontinuity it is ladder-like, motor in any position can self-starting, eliminate " torque dead-band ", circle
The aluminum conducting surface of arc is placed on outside rotor pole body, can improve the torque characteristics of motor, improves output power and transmission
Efficiency.
Present embodiment is only to the exemplary description of this patent does not limit its scope of protection, people in the art
Member its part can also be changed, as long as it does not exceed the essence of this patent, all the protection domain of this patent it
It is interior.
