15.	What is electric motor
Answer» Answer: An electric motor is an ELECTRICAL machine that CONVERTS electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire WINDING to generate force in the FORM of torque applied on the motor's shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or RECTIFIERS, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
