Abstract
A system for pumping fluid from a well-bore that includes a pump assembly driven by a first motor module assembly via a continuous rotatable shaft. The first motor module assembly includes an induction motor having a multi-phase stator and a wound rotor. Energizing the stator of the induction motor of the first motor module induces a current in the windings of the wound rotor of the induction motor of the first motor module. The induced current is supplied to a motor coupling unit which generates power to drive a second motor module assembly electrically connected to the motor coupling unit. The second motor module assembly further drives the pump assembly via the continuous rotatable shaft.
