Dcmotor isone ofthe main type ofmachine. Direct current (dc) can beconverted into mechanical energy (dc motor) orcan convert mechanical energy into direct current (dc generator) the rotation ofthe motor. Itistoachieve can direct current (dc) motor and mechanical energy conversion from each other, can beused asdcgenerator, dcpower supply indcmotor, because ofits superior performance ofspeed adjustment, requiring higher inmany high performance, iswidely used. Compared todcmotor and acmotor, plex structure, maintenance difficulties, the price ismore expensive, such asfaults, asacmotor widely used. But due tothe dcmotor has agood start, and brake performance ofspeedadjustment; therefore still has its place inthe industrial field.
