Do you know the difference between a stator and a rotor? An electric motor is a rotating machine that converts electrical energy into mechanical energy. Electric motors operate by the interaction between the motor’s magnetic field and an electric current in a wire winding to generate a force that results in shaft rotation. This course will address the two general types of electric motors by describing how they are constructed and the principles of operation of each type.
Describe the function, purpose and general design of both the AC Motor and DC Motor
Identify the differences between Alternating Current and Direct Current motors
Describe the three-phase stator and advantages of the Induction Motor
