CA 2268690

A method for restarting a motor of a submersible pump after a power interruption is disclosed. The system first detects when the power is turned back on to the system. A control means then samples signals sent back from the unpowered motor and determines the frequency and phase sequence of the signals. The speed and direction of operation of the motor are then determined from the determined frequency and phase sequence. A first pulse width modulation waveform is then applied to the motor matching the determined speed and direction of the motor. Finally, the output frequency of the waveform can be adjusted to adjust the speed and direction of operation of the motor until the motor reaches a desired speed and direction of operation.
