Brushless DC motor consists of synchronous motor and driver, which is a typical mechatronics product. Brushless motors have much less friction than brushed DC motors so they can operate at much higher speeds.
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.
