Product description YD series two-speed motors use variable stator windings to change the number of motor poles to achieve variable speed. The motor has the characteristics of varying the power and speed stepwise according to the different requirements of the load, so as to achieve a reasonable match with the load, which is of great significance to simplify the transmission system and save energy. Therefore, it is widely used in various transmission mechanisms that require stepwise speed regulation. Product related parameters Main specifications
