YEJ AC Asynchronous Crane Motor

Asynchronous Motor: 1 Big power 2 Fine process techniques 3 Good price

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.

Working condition:1,Ambient operation temperature: It may vary with the changing weather but never exceeding 40°C.2,Altitude: No more than 1000m3,Insulation Grade: B4,Protection Grade: IP445,Rated Volt: 380V6,Rated Frequency: 50Hz7,Arrester: IP238,Working System: Continuous S19,Cooling Type: IC 411Wiring: Y(the output is 3KW or below), others are Δ.

Brake mode:Braking without excitation; the power for braking comes from the rectifier in the connection box; Frame Size H100 or below it: AC220V-DC99V; Frame size over H112:AC380V-DC170V.
