OHS Series NEMA standard veritcal hollow shaft motor, also alled as VHS motor, is three phase squirrel cage induction motor, specially for driving verical deep well turbine pump.

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 ensurea longer oprating duration of the bearings.  The motors are characterized by high efficiency, large starting torque, low temperature rise, leakage free, quiet running, low vibration.

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