【摘要】 近年来,高速电机在各方面的应用得到广泛关注。由于高速电机的运行速度较高,其损耗中铁耗占有较大的比重,如何降低铁耗,提高效率是电机设计的关键。对一个应用于飞轮储能的20 000 r/min、三相永磁无刷直流电机进行了优化设计。最后分别按优化前后的方案做出样机并进行实验验证,结果表明,基于改进遗传算法的电机优化设计效果较为理想,有效地降低了电机铁芯损耗,提高了电机的运行效率。更多还原

【Abstract】 Recent year,high speed permanent BLDCMotor is getten more and more attention.But the higher the speed,the more the iron loss is.In order to improve the efficiency,that is minish the iron loss,an improved Adaptive Genetic Algorithm(AGA) is presented to optimize a 20000rpm,3-phase permanent brussless DC motor.Finally,two prototype motors are made,one is based the optimized scheme and one based the scheme before optimization.Experiment result proved that the optimization is effective.更多还原
