An armature in a motor is defined as rotating part of a motor that emits electric energy into a magnetic field. Other People Are Reading.
Since the armature windings of a direct-current motor are moving through a magnetic field, they have a voltage induced in them. This voltage tends to oppose the motor supply voltage and so is called  back electromotive force (emf) .n electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator.
