【Abstract】 A new magnet dimension designing method of rare-earth PM brushless DC motor is presented, which is, after the air gap flux density is preliminarily assumed, that the drops of the magnetomotive force of the air gap, stater and rotor are calculated one by one, then the work point of the magnet is defermined, and finally the magnet dimensions are defermined and optimized. An improved and complete computer program of rare-earth PM brushless DC motor is finished. After experiments on one sample motor, the results of the no load and load experiments are compared with the elesigning datas, they are perfectly identical.更多还原
