The invention discloses a kind of axial flux permanent magnet synchronous magnetic resistance motor, the logarithm of permanent magnet piece is in 4 on the hop count and rotor of the motor stator:5 proportionate relationship, the multiple that stator segment number is 4, number of motor phases are 4 phases.The structure can improve output torque, can reduce torque pulsation compared with common three-phase axial direction electric machine and radial reluctance motor.
Description
Technical field
The present invention relates to a kind of axial flux permanent magnet synchronous magnetic resistance motors, belong to the technical field of motor manufacturing.
Background technology
Axial flux permanent magnet synchronous magnetic resistance motor is a kind of novel electric machine structure, reluctance motor be also with common friendship,
A kind of different motor of dc motor, reluctance motor are to generate torque by " magnetic resistance minimum principle ", current many applications
Field requires the output torque of motor big, and torque pulsation is small, is just proposed to the output torque of motor, volume and weight tightened up
Requirement.
The winding of existing axial magnetic flux reluctance motor or radial flux reluctance motor is much to use 4:3 structures, i.e., it is fixed
The hop count and rotor permanent magnet piece logarithm of son are in 4:3 proportionate relationship, the multiple that stator segment number is 4, pair of rotor upper magnet yoke
The multiple that the logarithm of number or permanent magnet is 3 when operating, while having the energization of two phase windings.
4:The first problem that 3 structure reluctance motors are brought is, since electric machine structure cannot preferably be turned using motor surely
The electromagnetic energy of son, the output torque of motor is not big enough, prevents motor from obtaining larger torque density, cannot effectively mitigate
Motor volume and weight do not utilize the volume and weight of motor effectively.
4:The Second Problem of 3 structure reluctance motors is, since rotor permanent magnet number is less, motor output is made to turn
The pulsation of square is also bigger, to cause motor to produce larger vibration and noise problem.
Invention content
The object of the present invention is to provide a kind of axial flux permanent magnet synchronous magnetic resistance motors that can reduce torque pulsation.
4：3 structure permanent-magnet synchronous reluctance motors relative position of permanent magnet and stator winding in rotation process determines together
The most two phase windings actings of one moment, the acting if third phase winding is also powered, the attraction or repulsive force of formation will hinder electricity
Machine rotates.If designing a kind of motor, four quite middle three-phases of a motor may be implemented while doing work, then can do
To reduction motor torque ripple and increase torque density.
In order to achieve the above objectives, the technical scheme is that：A kind of axial flux permanent magnet synchronous magnetic resistance motor, including it is fixed
Son and rotor are provided with pairs of permanent magnet piece on rotor, and the hop count and rotor permanent magnet piece logarithm of the motor stator are in 4:5
Proportionate relationship.Due to this 4：5 structural electromotors use more rotor permanent magnet sections, relative to 4：For 3 structural electromotors, permanent magnetism
Body number is more, and motor peak torque is interval smaller, reduces the torque pulsation of motor.
The multiple that stator segment number is 4, entire motor are four phases, and two sections of adjacent windings are around to opposite in each phase.Often
One mutually all stator segments are connected in series with, and each phase winding is mutual indepedent, can independently be driven.Using four phase structures, in the running,
And making in four phase stator winding while having three-phase energization, such motor can generate the electromagnetic torque of bigger, just improve motor
Torque density.
Stator segment is evenly distributed around motor center shaft.
Permanent magnet piece, permanent magnet magnetizing direction are along axis direction, and the magnetic line of force direction of adjacent permanent magnet piece is phase
Instead, two panels permanent magnet axially is a pair, and magnetic line of force direction is identical.Different magnetic force on rotor can be utilized simultaneously in this way
The permanent magnet in line direction.
Of the present invention 4:5 proportionate relationship is in order to make permanent magnetism piece volume in suitable range, according to more at high proportion
（Such as 4：7 ratios）Then the volume of permanent magnet piece is in the necessary smaller of same motor diameter, when this can cause motor to drive
The commutation time is short, or even the performance range beyond circuit.
Maintaining 4:The number and size for changing stator segment and permanent magnet piece in the case of 5 ratios, can be obtained different volumes
With the motor of power.
