Electric power is supplied to load making use of plural power sources. Making use of the trigger system, the ripple component of the input electric current which is introduced into the system is cancelled automatically substantially. Master power source and slave power source supply electric power ...
直流电动机从接通电源开始转动,直至升速到某一固定转数稳定运行,这一过程称为电动机的启动过程。直流电动机有全压启动、变阻器启动和降压启动三种方法。 a.全压启动。全压启动就是将电动机直接接入到额定电压的电源上启动。由于电动机所加的是额定电源,而电动机开始接通电源瞬间电枢不动,电枢反电动势E。为零,所以启动...
直流电机定子部分主要由主磁极、换向极、机座和电刷装置等组成。 (1)主磁极 又称主极。在一般大中型直流电机中,主磁极是一种电磁铁。只有个别类型的小型直流电机的主磁极才用永久磁铁,这种电机叫永磁直流电机。主磁极的作用是能够在电枢表面外的气隙空间里产生一定形状分布的气隙磁密。
