Variable speed of the motor by changing winding single phase motor connection mode, that is to say, with a rotating magnetic field of magnetic pole change motor logarithmic to change its speed. If your unit's Electric motor two-speed motor (fan), low speed at ordinary times, sometimes fan on high speed turning, mainly through external control circuit switch to change the motor coil winding connection. 1, there are two different embedded in the stator slot logarithm of winding, by changing the external control line to change of motor stator winding connection to realize the logarithm change poles; 2, in the stator slot electric generator embedded, there are two different polar logarithmic independent winding; 3, in the stator slot is embedded, there are two different logarithmic independent winding, and each winding can have different connection again.
