Abstract:
A converterless motor-driven pump system includes an off-grid prime mover. The off-grid prime mover has a rotational driveshaft and operates in response to a throttle control command to control a rotation speed of the rotational driveshaft. An electric power generator is driven by the off-grid prime mover to generate AC power. A variable speed induction motor is directly powered by the electric power generator. A pump that may be submersible is driven by the at least one variable speed induction motor. A system controller that may be local or remote is programmed to generate the throttle control command in response to one or more pump operating characteristics such that the off-grid prime mover, the electric power generator, and the variable speed induction motor together operate to regulate a pressure at the inlet of the electric pump.
