Question

What energy conversion does take place during the working of a d.c. motor ?

Answer 1

Almost every mechanical movement that we see around us is accomplished by an electric motor. Electric machines are a means of converting energy. Motors take electrical energy and produce mechanical energy. Electric motors are used to power hundreds of devices we use in everyday life. The input is electrical energy (from the supply source), and the output is mechanical energy (to the load).
Electrical energy is converted into mechanical energy by a d.c. motor.
