Abstract

Abstract:

Approximately rectangular no-load air-gap flux density waveform of traditional tile surface mounted permanent magnet motor had high harmonic content in the back EMF, large torque ripple and easy to bump damage in the rotor assembly process, a novel surface mount hyperboloidal pole structure composed of permanent magnet and magnetic metal shoe was presented. Then, no-load air-gap flux density and cogging torque was calculated, and the corresponding harmonics and sinusoidal distortion rate of air-gap flux density were obtained by Fourier decomposition. Build the hyperbolidal pole structure parameters of the mode. Taking minimizing the cogging torque and maximizing the electromagnetic torque as the target, this paper design a surface mounted hyperboloidal pole permanent magnet motor by cloud genetic strategies (CGS). The design results show that cogging torque and other performance are better than initial model. At last, the simulation is made according to finite element method. The no-load and load test also made after built the prototype motor. Both the results of finite-element simulation and test are verified the design modeling and the optimal method correctly.

Key words: Cloud genetic strategy, permanent magnet motor, surface mounted hyperboloidal pole-shoe, torque ripple
