Product Description

OHS Series Vertical Hollow Shaft Motor (VHS Motor) are vertical hollow-shaft three-phase squirrel cage induction motors specially for driving vertical deep-well turbine pumps. The protection degree is weather-protected type 1 (drip-proof) and the rated voltage is 460V 60Hz.

We can also provide with rated 380/660V on request. Adopting an internationally advanced structure of anti-reverse, the motors are exact and reliable for preventing the reversal. The motors are employed with the oil-immersed bearing lubricating construction, which makes the bearings running in a condition of satisfactory cooling and lubrication so as to ensure a longer operating duration of the bearings.

The motors are characterized by high efficiency, large starting torque, low temperature rise, leakage free, quiet running, low vibration, etc.

Through our innovative research and development, series OHS deep-well pump motors transcend the traditional mode of motor construction, which leads to a stable and increased efficiency of the motors.

As a domestically initiative product, the motors reach the international advanced level 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, factory and so forth.
