C.R.I. “W series” motors are deep well / bore hole rewindable submersible type, pre-filled with water, which acts as coolant and lubricant. These motors are available in single phase and three phase power supply. All single phase motors are thermally protected . Rotors are supported with bush and thrust bearings to withstand maximum axial and radial thrust loads. All mounting dimensions are in accordance with NEMA standards.
