Abstract
An inducer pump located internally in an electrical submersible pump motor enhances lubricant circulation within the motor. The inducer is located at the lower end of the shaft within a shaft bore. The inducer has a rod and a helical flight rigidly mounted to the rod. The inducer rotates in unison with the motor, pumping lubricant from a lower lubricant chamber upward through the shaft bore.
