Multi speed motors are used in situations where there multiple speed controls are necessary. This is achieved by changing the number of poles to obtain different speeds. By adjusting the pole, the power consumed is also adjusted too. Thus, this also allows energy savings by lowering motor speed to minimize power consumption.
 
Three speed motor is usually used for more demanding application where precise speed controls are necessary. Please do not hesitate to contact us directly so that we can cater to your specific needs.
