This patent describes a well having casing containing formation fluid, an improved means for pumping the fluid to the surface. It comprises: a centrifugal pump located within the well; a submersible three-phase electrical motor located within the well and coupled to the pump for driving the pump; a cable having a conductor, the cable having a lower end connected to the motor and an upper end extending to the surface, the cable having sufficient strength to support the weight of the pump and motor, allowing the pump and motor to be lowered into and retrieved from the well on the cable; means for supplying single-phase AC power from the surface down the conductor; and means located at the lower end of the cable for converting the single-phase AC power to three-phase electrical power to power the motor.
