Shaded pole motor has two
shaded pole ring (also called short-circuit ring), shaded pole ring can hinder
the transfer of magnetic field lines in a magnetic field, The part no shaded
pole ring is stronger than the part have shaded pole ring of the magnetic field
strength, which form a rotating magnetic , the difference of magnetic field force on it, this cases will have a
rotational force acting on the rotor, which is to make motor start work.
As single phase shaded pole motor coil through single-phase AC
power, we know that the spread of the single-phase AC power is a form of a
sinusoidal AC curve.
Take 220v 50hz(china market) for example its direction can transform
50 times in one second.we know that when we pass into the shaded pole coil
voltage, power coil will produce the direction of the magnetic field, the
magnetic field lines and current direction is closely related to the direction
of the right-hand rule to determine the magnetic field lines.
