YEJ Series Brake Three-phase ASynchronous motor





General description

YEJ Series Motor is designed on the basis of A Series Motor, through adding a disk DC electro-magnetic brake between the fan end, endshield, and the fan itself. It features high efficiency, energy saving, high value of startup toque, prompt braking, accurate positioning, simple structure, easy operation, small vibration, long longevity and the rotor 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.
