TXZ Big Starting Torque Large Synchronous Motor 500r/Min

TXZ Large Synchronous Motor Big Starting Torque

TXZ series synchronous motor, the main speed is 250r/min, this series of motors is installed at an angle of 30°, mainly used for drainage pumping stations, the protection grades are mainly IP20, IP21, IP23

Widely used in petroleum, chemical, coal and other industries to drag reciprocating compressors, working in the explosive gas environment of "2" zone. Under normal working conditions, the altitude does not exceed 1000m, the maximum ambient air temperature does not exceed +40°C, and the minimum ambient temperature is -5°C.
