Applications of DC Motor [ Series, Shunt Compound Motor

Introduction. D.C motor is an electrical motor which only runs on dc supply. The traditional DC motor needs two current supplies, one through the stator windings to provide the magnetic field and the other through the rotor windings to interact with the magnetic field to generate the motive force. Currently, series, shunt, and compound motors are used which require only one voltage supply. dc Get price
