The induction motor is the single excited motor, i.e., the supply is applied only to the one part, i.e., stator. LINEAR INDUCTION MOTOR - Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. Its main function is to support the stator core and the field winding. In a traditional electric motor, the rotor (rotating part) spins inside the stator(static part); in a linear motor, the stator is unwrapped and laid out flat and the "rotor" moves past it in a straight line.
