Series OHS Motor

Series OHS motors vertical hollow-shaft three-phase motors squirrel cage induction motors specially for driving vertical deep-we The protection degree is weather-protected type 1 (drip-proof) and the rated voltageis 460V, 60Hz. We can also provide rated 380/660V, 50HZ on request. Adopting internationally advanced structure of anti-reverse, the motors are exact and reliablefor preventing the reversal. The motors are employed with the oil-immersed bearinglubricating construction, which makes the bearings running in a condition of satisfactory cooling and lubrication so as to ensure longer operating duration ofthe bearings. The motors are characterized by high efficiency, large starting torque,low temperature rise, leakage free, quiet running, and low vibration. Throughour innovative research and development, series OHS deep-well pump motors transcend the traditional mode of motor construction, that leads to a stable andincreased efficiency of the motors. Series OHS motors vertical hollow-shaft three-phase motors squirrel cage inductionmotors specially for driving vertical deep-well turbine pumps. As a domestically initiative product, the motors reach the international advancedlevel of the latest NEMA Standard. After being fitted with long-shaft typed pumps,the motors are widely used in pumping underground water in mine, city, farm,and factory.
