What is a two-speed motor

What is a two-speed motor Speed regulating pole double-speed asynchronous electric motors belong to variant,is by changing the connection of the stator winding the logarithmic method to change the

stator rotating magnetic field poles,which changes the Motor vehicle speed of the motor.A two-speed motor variable speed principle Variable speed of the motor by changing winding connection mode,that is to say,with a rotating magnetic field of magnetic pole change motor logarithmic to change its speed.Two-speed motor (fan),low speed at ordinary times,sometimes fan on high speed turning,mainly through the following external control wholesalemotor.blogspot.com circuit switch to change the way 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 asynchronous motor stator slot 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.
