YZEJ series electromagnetic brake three-phase asynchronous motor for construction hoist
YZEJ series electromagnetic brake three-phase asynchronous motor for construction hoist is a three-phase asynchronous motor specially developed for the electric drive of construction hoist and other construction machinery, which meets the requirements of GB755-87 "Basic Technical Requirements of Rotating Motor" and JB/T7841-2005 "Technical Conditions of YZZ Series Electromagnetic Brake Three-phase Asynchronous Motor for Hoist" of the national standard. The motor has the characteristics of large starting torque, small starting current, high efficiency, small temperature rise, low noise, strong overload capacity, etc. Moreover, because the braking part of the motor adopts buffer and delay technology, which makes the motor start and brake more smoothly, and the brake adopts the function of automatic tracking compensation of the friction sub gap, which saves the user the trouble of adjusting the friction sub, so the motor has the characteristics of simple use and convenient maintenance.
