YEJ Series Electromagnetism-brake Three-phase Asychronous Motor
Description
 YEJ Series Motor is designed on the basis of Y Series Motor, through adding a disk DC electromagnetic brake between the fan end, endshield, and the fan itself, It features high efficiency, energy saving, high value of startup torque, prompt braking, accurate positing, simple structure, easy operation, small vibration, long longgevity and the protor has no axial float when braking. It has been widely used in various machines that need prompt braking, accurate positioning and reciprocating motion, such as the machinery for crane, foodstuff, light industry packing, and printing, construction, etc.
