Design is defined as a creative physical realization of theoretical concepts. An electric machine is an electro-mechanical energy conversion device, which converts mechanical energy into electrical energy and vice versa. When the machine converts mechanical energy into electrical energy it is called as generator. When the machine converts electrical energy into mechanical energy it is called as motor. A part of energy is converted to heat. This energy is lost and cannot be recovered. An electrical machine can be designed to operate either as a generator or as a motor.
