YDseries change-pole muilti-speed three phase asynchronous motors are designed 380 v , 50Hz,IP44,cooling methodIC411,self fan cooled Insulation Class F . it has the same structure , Installaion Method and outline dimensions as YE2 series.
Among YD series , two-speed has one winding and three-speed has two windings. It changes the poles of the elactric motorby change winding connection method. This senies implement YD Series (IP44) Three Phase Asynchronous Motors TechnicalSpecifications. it can change the speed in stages as the loads change to make the power match suitably and simplify the speedcontrol system . it is applied to step by step transmission mechanisms.YD series is widely used in universal, multiple and specifictuming machines as well as metallturgy,textile , printing dyeing, chemical and agricultural industries.
