L type winding tap speed regulating motor

The speed regulation of electric fan motors mostly uses winding coil
taps, which actually means changing the number of winding coils, thereby changing the intensity of the magnetic field generated by the stator coil and achieving speed adjustment.
    The figure shows the winding structure of a wall-mounted electric fan motor. There are two taps in the running winding, so that a three-
speed variable electric fan motor can be realized . Since the two sets of coils are connected in an L-letter shape, it is also called an L-shaped winding structure.
