Abstract: A system and method for supplying power to a variable speed motor for rotating a shaft may include generating an A/C output having a variable frequency corresponding to speed of a prime mover, where the speed of the prime mover is equal to or greater than a predetermined speed limit. The A/C output of the prime mover may be distributed to the variable speed motor such that the speed of the variable speed motor is varied relative to the frequency of the A/C output. The variable speed motor may be electrically disconnected from the A/C power when the speed of the prime mover being used to drive the variable speed motor is equal to or within a predetermined range of the predetermined speed limit. An alternate A/C output may be distributed to the variable speed motor after the A/C power is electrically disconnected from the variable speed motor.

Abstract: A power distribution system is provided for supplying power to a variable speed motor for rotating a shaft. The system comprises a variable speed prime mover adapted to generate an A/C output having a variable frequency corresponding to the speed of the prime mover, a power switch, a power distribution bus connected to the A/C output of the prime mover and connected, via the switch, to the motor such that the motor's speed is varied relative to the frequency of the A/C output, and a variable frequency drive operatively connected to the A/C output of the prime mover via the bus and effective to provide an alternate A/C output to the motor after the motor is disconnected from the bus. The switch is adapted to disconnect the motor from the bus when the prime mover's speed is equal to or within a predetermined range of the prime mover's speed limit.
