Description
Technical field
The utility model relates to a kind of axial flux permanent magnet synchronous magnetic resistance motors, belong to the technical field of motor manufacturing.
Background technique
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, just proposes 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 structure, i.e., fixed
The number of segment and rotor permanent magnet piece logarithm of son are in the proportionate relationship of 4:3, the multiple that stator segment number is 4, pair of rotor upper magnet yoke
The multiple that several or permanent magnet logarithm is 3 when operating, while having the energization of two phase windings.
4:3 structure reluctance motor bring first problem 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 biggish torque density, cannot effectively mitigate
Motor volume and weight do not utilize the volume and weight of motor effectively.
The Second Problem of 4:3 structure reluctance motor is, since rotor permanent magnet number is less, turns motor output
The pulsation of square is also bigger, so that motor be caused to produce biggish vibration and noise problem.
Summary of the invention
The purpose of the utility model is to provide the axial flux permanent magnet synchronous magnetic resistance motors that one kind can reduce torque pulsation.
The relative position of permanent magnet and stator winding determines together 4:3 structure permanent-magnet synchronous reluctance motor during rotation
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 rotation.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 solution of the utility model are as follows: a kind of axial flux permanent magnet synchronous magnetic resistance motor, packet
Stator and rotor are included, pairs of permanent magnet piece is provided on rotor, the number of segment and rotor permanent magnet piece logarithm of the motor stator are in
The proportionate relationship of 4:5.Since the 4:5 structural electromotor uses more rotor permanent magnet sections, come relative to 4:3 structural electromotor
It says, permanent magnet number is more, and motor peak torque smaller interval 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, and each phase winding is mutually indepedent, can independently drive.Using four phase structures, in the running,
And making in four phase stator winding while having three-phase energization, such motor can produce bigger electromagnetic torque, 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.Magnetic force different on rotor can be utilized simultaneously in this way
The permanent magnet in line direction.
The proportionate relationship of 4:5 described in the utility model is in order to make permanent magnetism piece volume in suitable range, according to higher
The volume of ratio (such as 4:7 ratio) then permanent magnet piece must be smaller in same motor diameter, this will lead to motor drive
The commutation time is short when dynamic, or even the performance range beyond circuit.
The number and size for changing stator segment and permanent magnet piece in the case where maintaining 4:5 ratio, can be obtained different volumes
With the motor of power.
