Depending upon the source of electrical energy, there are two types of electric motors: A.C. Motors: Motor that converts alternating current energy into mechanical energy is called A.C. motor. D.C. Motors: Motor that converts direct current energy into mechanical energy is called D.C. motor.OWER LOSSES IN A DC MOTOR. The basic function of dc motor is to convert electrical energy into mechanical energy. Whole of the input energy is not converted into useful output energy but a part of the input energy is converted into heat and the same is lost.
