Research on NdFeB Permanent Magnet Synchronous Motors Optimization Design

This paper introduces a way of usingSUMT method combined with improved Hoke-Jeevesmethod to conduct optimization design for NdFeB PMsynchronous motors.The 4kw,4 pole NdFeB PM synchronous motor is taken here as an example to demonstrate the optimization design. On condition of being fulfilled with all the motor's quality index,we obtain themotor's most proper and coordinate size and therefore cutinto the motor's magnet amount as well as the motor'scost,thus achieving obvious economic profits. By evaluating foe optimiaztion result and its method, the paperproves the method applied in the process is really workable.In addition, motor's optimization project can beavailable in a short time by applying this method.
