TV, radio, and stoves do not normally have motors in them.
electric cars and fans in cars use DC motors
the other devices use AC motors.
AC motors have simple rings to carry current to the spinning part and lock to the changing AC current to get a pulse of movement from each half of the sine wave of current.
DC motors must have multiple sections on the rotating part so that the fixed magnetic field on the outside is constantly being pulled on by different sections of the rotating part.
If that is not what you wanted, clarify.
