Coimputer- the motor drives fan for the cpu Printer- a motor drives the print head Washine machine- drives the paddle which recycles water and detergent solution electric fan- motor drives the fan or blower electric car-acts as prime mover for the car microwave oven- drives a fan and turn table tv- not all have motors radio- ordinary radios are without motors stoves- electric stoves are without motors but electric ovens have rotissure driven by small motors
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.
