YZREYZRE Series Electromagnetic Brake Wound Rotor Three-Phase Asynchronous Motors for Crane and Metallurgical Use
Wound Rotor Crane Motor with Brake XINDALI YZRE
YZRE is a YZR wound rotor motor with a built-in DC electromagnetic disc brake; the design complies with the Chinese machinery industry standards JB/T 7077 and JB/T 7563. According to the catalogue tables it covers frames H112–250, 1.5–45 kW at S3 40%, 6 and 8 poles, 380 V 50 Hz. Rated static braking torque is 15–445 N·m in the travel version and 30–890 N·m in the hoisting version, and the torque is adjustable. It is a compact motor-and-brake unit for mechanisms with frequent starting, stopping and overloads. The squirrel cage counterpart is YZE.
