Motors work on the principle of converting electrical energy into mechanical energy.

• Motors use the interaction between magnetic fields and electric currents to generate force and motion.

• They consist of a stator (stationary part) and a rotor (moving part).

• The stator contains coils of wire that produce a magnetic field when an electric current passes through them.

• The rotor, usually made of a permanent magnet or electroma...read more
