Electromagnetic Analysis and Parameter Optimization of Auxiliary Magnetic Barrier Permanent Magnet Synchronous Motor

The auxiliary magnetic barrier permanent magnet synchronous motor not only has the advantages of high power density, high efficiency and high power factor, but also combines the advantages of wide speed control range and no high temperature demagnetization of synchronous reluctance motor. Based on optimizing the shape of the magnetic barrier, the shape of the peripheral bridge, the number of layers of the magnetic barrier and the proportion of the auxiliary magnetic barrier permanent magnet synchronous motor, compared the auxiliary magnetic barrier permanent magnet synchronous motor with "—" type and "V" type interior permanent magnet synchronous motor. The performance of load torque, torque ripple, loss and efficiency of the three structures are compared by two-dimensional finite element simulation software.In order to reduce the effective value of tooth slot torque, reduce the harmonic content of no-load backward potential and increase the effective value of load torque, the rotor structure of auxiliary magnetic barrier permanent magnet synchronous motor is optimized, which has certain reference value for the popularization and application of auxiliary magnetic barrier permanent magnet synchronous motor.
