    en.wikipedia.org/wiki/Shaded-pole_motor

    A shaded-pole motor is a small motor with either two or four poles, in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole to produce a weakly rotating magnetic field. [2] When single phase AC supply is applied to the stator winding, due to shading provided to the poles, a rotating magnetic field ...

  7. Permanent magnet motor - Wikipedia
