A low power dc motor with electronic commutation. Also known as commutatorless motor, DC motor without commutator. Compared with other types of motors, brushless motors have a very efficient operation, meaning lower power consumption at the same power output compared with brushed DC motors.
A Shaded Pole motor is an AC single phase induction motor. The auxiliary winding, which is composed of a copper ring, is called a shading coil. The current in this coil delay the phase of magnetic flux in that part of the pole in order to provide a rotating magnetic field. The direction of rotation is from the unshaded side to the shaded ring.
