Please refer to Fig.1, the utility model embodiment provides a kind of rotor core, including rotor body 1 and being arranged at turns Permanent magnet trough 2 on sub- body 1, is provided with for fixed rotor punching on the rotor magnetic pole between two adjacent permanent magnets groove 2 Mounting hole 11,2N every bore 12 and 2M via hole 13,2N is a to be symmetrically arranged every bore 12 and 2M via hole 13 In the pole center line both sides of rotor magnetic pole.That is, the 2N pole center line both sides that rotor magnetic pole is symmetrically disposed on every bore 12, Also, 2M via hole 13 is symmetrically disposed on the pole center line both sides of rotor magnetic pole.It is located at the outer of mounting hole 11 every bore 12 Side, via hole 13 are connected with permanent magnet trough 2;Every the width of bore 12 and via hole 13 along the center of circle of rotor body 1 to its outside Direction increase.Also, close to pole center line two magnetic pole entity parts between bore 12 width along rotor sheet Outer lateral its center of circle direction increase of body 1.
The utility model embodiment provide rotor core, every bore 12 width along the center of circle of rotor body 1 to outside it The direction increase of side, close to pole center line two magnetic pole entity parts between bore 12 width along rotor body 1 Outer lateral its center of circle direction increase so that two magnetic pole entity parts between bore 12 are by the outer lateral of rotor body 1 The direction of mounting hole 11 broadens, and effectively ensure that the position of mounting hole 11 avoids and opens every bore 12, it is ensured that rotor body 1 turns Mounting hole 11 and the mechanical strength after bore 12 are opened up on sub- magnetic pole;Also, due to interior for sky every bore 12 and via hole 13 Gas, the magnetic conductivity of air are less than the magnetic conductivity of rotor core material (entity part of rotor body 1).By opening up every bore 12 And via hole 13, thus it is possible to vary the magnetic flux trend in rotor magnetic pole, via hole 13 are connected with permanent magnet trough 2, facilitate mounting hole 11st, every bore 12 and the arrangement of via hole 13, also, the position that opens up of via hole 13 and shape further limit walking for magnetic flux To, and then improving the distribution of air-gap field so that the Waveform sine of air gap flux density is more preferable, reduces air gap flux density, back-emf Harmonic wave accounting, effectively reduces the vibration noise of motor.
It is understood that the width of two magnetic pole entity parts between bore 12 is it along perpendicular to rotor body The distance between 1 both sides of radial direction.Every bore 12 width for its along perpendicular to rotor body 1 radial direction two The distance between stomidium wall.Wherein, it is provided with fixing piece in mounting hole 11.When mounting hole 11 is rivet hole, fixing piece is Rivet;When mounting hole 11 is screw hole, the structural strengthening bar of insertion connection rotor punching in screw hole.Can also be by mounting hole 11 are arranged to other kinds of hole, such as threaded hole, prism hole or elliptical aperture.
Further, via hole 13 close to the outside hole face in the outside of rotor body 1 to forming the between 1 outer wall of rotor body One magnetic bridge, the width of the first magnetic bridge is A, and it is D that rotor core, which is used for the gas length that stator coordinates,.By simulation study It was found that the presence of via hole 13 and thickness are larger to back-emf harmonic effects.If without the first magnetic bridge, i.e. via hole 13 runs through The lateral wall of rotor body 1, contacts with air gap so that the gas length at this lengthens, and air-gap permeance reduces, air-gap field distribution Inequality, air gap magnetic density waveform distortion, air gap flux density, the increase of back-emf harmonic wave accounting, the vibration noise of motor increase.When with During one magnetic bridge, which, close to air gap, can be effectively improved air-gap field distribution close to the outside of rotor body 1. As shown in figure 5, as A/D >=1, it is allowed to which sub-fraction magnetic flux preferably improves magnetic in magnetic pole by the first magnetic bridge transmission Logical trend, improves the distribution in motor gas-gap magnetic field, reduces harmonic wave accounting, reduces torque pulsation, reduces motor oscillating noise.But That, as A/D > 1.6, the width of the first magnetic bridge is excessive, most of magnetic flux still can by the first magnetic bridge to air gap transmission, Improvement influence on air-gap field distribution is smaller, and harmonic wave accounting is still larger, and the vibration noise of motor does not reduce.It is therefore preferable that Ground, 1.6 >=A/D >=1.
Further, the length of via hole 13 is J, and the magnet steel length of permanent magnet trough 2 is G.Found by research, via hole 13 extend towards rotor radial direction, since via hole 13 is close to permanent magnet trough 2, the length J of via hole 13 is longer, to forever The influence of magnet flow bang path is bigger.It is air in via hole 13, magnetic conductance is small, makes as shown in fig. 6, as J/G >=0.1 Obtain magnetic flux of the permanent magnet close to rotor outer circle direction more to transmit along in the middle part of magnetic pole, by above-mentioned setting, can preferably limit Magnetic flux trend in rotor processed, optimizes the distribution of air-gap field, reduces harmonic wave accounting and torque pulsation, thus reduces motor and shake Moving noise.But as J/G > 0.35, the length J of via hole 13 is long, the excessive resistance of magnetic flux of the via hole 13 to permanent magnet Every the magnetic linkage of motor reduces, and the output of motor reduces, and electric efficiency declines.Therefore, 0.35 >=J/G >=0.1.
Wherein, the length of via hole 13 be J be via hole 13 apart from the outside of rotor body 1 closest approach and via hole 13 away from The distance between closest approach from 1 center of circle of rotor body.

Preferably, the outside of via hole 13 extends along rotor circumference direction, the outside of via hole 13 court in the circumferential direction of the rotor Pole center line extends, and closer to pole center line, the width in the outside of via hole 13 is wider.
Preferably, the one end in via hole 13 towards 1 center of circle of rotor body is connected with permanent magnet trough 2;Via hole 13 is towards forever There is the second magnetic bridge between the side wall and permanent magnet trough 2 of magnet slot 2.It is air by above-mentioned setting, in via hole 13, magnetic conductance Small, therefore, magnetic flux is small in the second magnetic bridge, further optimizes the air-gap permeance uniformity of magnetic circuit, further optimizes air gap magnetic Field distribution, reduces air gap flux density, back-emf harmonic wave accounting and harmonic loss, reduces vibration noise, improve electric efficiency.
In the present embodiment, it is thin in the outer thickness of via hole 13, i.e. via hole 13 is on the circumferencial direction of rotor body 1, outside it Side width is more than inboard width.
In the present embodiment, the width that via hole 13 connects position with permanent magnet trough 2 is P, and rotor core is used to match somebody with somebody with stator The gas length of conjunction is D.Found by research, via hole 13 is connected with permanent magnet trough 2 so that permanent magnet is passed by connected component The magnetic flux passed is reduced, and as P/D >=0.5, changes the magnetic flux path in rotor magnetic pole, and then improve air-gap field distribution, drop Low harmonic wave accounting and motor oscillating noise.But as P/D > 2, via hole 13 connects the width P at position with permanent magnet trough 2 Excessive, the increase of connected component magnetic resistance, limits the utilization of permanent magnet magnetic flux, and the utilization rate of permanent magnet reduces, and the magnetic linkage of motor subtracts It is small, then so that electric efficiency declines.It is therefore preferred that 2 >=P/D >=0.5.
The width of second magnetic bridge increases along the center of circle of rotor body 1 to the direction on the outside of it.It reduce further motor Vibrating noise.
Preferably, the second magnetic bridge is T close to the distance between two endpoints in the outside of rotor body 1, rotor core Gas length for coordinating with stator is D;4.5≥T/D≥2.5.Pass through above-mentioned setting so that a part of magnetic flux of permanent magnet By the second magnetic bridge transmission, further improve air-gap field distribution, reduce back-emf harmonic wave accounting, reduce motor oscillating and make an uproar Sound.
