China Semc Yzrw Eddy Current Brake Hoisting Metallurgical Motor

YZRW series eddy current brake wound rotor three-phase asynchronous motor for hoisting and metallurgy is composed of YZR series motor and eddy current brake installed on its auxiliary shaft extension. It integrates two functions of drive and speed regulation: stable low-speed speed regulation, no out of control and reliable operation.
2. The eddy current brake motor can operate normally under the following environmental conditions:
(1) The temperature of cooling medium shall not exceed 60 ºC (motor with class H insulation) or 40 ºC (motor with class F insulation);
(2) Altitude not more than 1000m;
(3) Frequent and significant mechanical vibration and shock.
3. Eddy current brake motor is a derivative product of wet tropical climate environment. Its winding and surface protective layer are specially impregnated and treated. In addition to the provisions of Article 2, it can operate normally under the following environmental conditions.
(1) At 25 ºC, the monthly average maximum relative humidity of the wettest month is 90%;
(2) Minimum ambient air humidity - 15 ºC;
(3) Frequent starting and braking.
