Description
Technical Field

The shaded pole type single-phase asynchronous motor is characterized in that a copper ring (short circuit ring) is sleeved on about 1/3 of the pole face of a stator pole of the single-phase asynchronous motor, and the pole part sleeved with the short circuit ring is called a shaded pole. After the stator winding is charged with current to generate a pulsating magnetic field, a part of magnetic flux passes through the copper ring, so that induced electromotive force and induced current are generated in the copper ring. According to lenz's law, the magnetic field generated by the induced current in the copper ring prevents the magnetic flux in the copper ring portion from changing, with the result that the magnetic flux in the portion of the pole not covered with the copper ring is out of phase with the magnetic flux in the portion of the pole covered with the copper ring, and the magnetic flux outside the shaded pole leads the magnetic flux in the shaded pole by a phase angle as if the magnetic flux always moves from the unshielded portion to the shaded pole portion.
