An electric DC motor basically converts direct electrical energy into mechanical energy. An electric DC motor’s speed is able to be varied over a broad range, by providing a variable supply voltage or by fluctuating the strength of the current in its field windings. A small DC electric motor is widely used for small tools, […]
