Reversibility principle, Electrical Engineering

The reversibility principle of electrical machines states that an electrical machine can be used to operate either as a motor, converting electrical to mechanical energy, or as a generator doing the reverse, i.e. converting mechanical to electrical energy.
 
The  module  will  therefore  also  be concerned with electrical generation. In addition to drives and actuators, the module  will  include a study of transformers.These  also rely on electromagnetic principles, but are not intended to produce mechanical motion. They are widely used in electromechanical systems for 'stepping up or down' the magnitude of an AC voltage or current.

To understand how motors and generators work,  it  is first necessary to review  the basic electromagnetic  principles  upon which they depend.
