Non-Destructive Testing Techniques

In our previous work, soft magnetic composite (SMC) material was employed to design cores for two kinds of permanent magnet (PM) synchronous motors, namely transverse flux motor and claw pole motor.This paper presents robust design optimization method for the quality control of these PM-SMC motors to improve their industrial applications.Besides traditional theoretical design and analysis, manufacturing condition, tolerance, noise factors and manufacturing costs are investigated in the robust design and optimization models in order to achieve six sigma quality manufacturing for these motors.Thereafter, a PM-SMC transverse flux motor is investigated to illustrate the performance of the proposed method.From the discussion, it can be found that the proposed method can significantly improve the manufacturing quality and reliability of the motor, and reduce the manufacturing cost as well.
