YD SERIES VARIABLE STAGE MULTI SPEED THREE-PHASE ASYNCHRONOUS MOTOR

YD series change-pole multi-speed three phase asynchronous motors are designed 380 V,50Hz,IP44,cooling method IC411,self fan cooled insulation Class F,lt has the same structure,installation Method and outline dimensions as YE2 series.

Among YD series,two-speed has one winding and three-speed has two windings.lt changes the poles of the electric motor by  change winding connection method.This series implement YD Series  (IP44)Three Phase Asynchronous Motors Technica Specifications.lt can change the speed in stages as the loads change to make the power match suitably and simplify the speed control system.lt is applied to step by step transmission mechanisms.YD series is widely used in universal,multiple and  specific turning machines as well as metallurgy,textile,printing
