Abstract:

A rotordynamic system includes a vertically arranged motor, rotordynamic device and controller. The rotordynamic device is a centrifugal pump or compressor operated by the motor to drive a fluid from the input to the output. A liquid cooling system operates to maintain the controller and motor at a desired operating temperature. Due to the liquid cooling system, the controller operates the motor at effectively any practical speed. The liquid cooling system is in heat exchange relationship with an oil system contained within the motor to distribute thermal energy therebetween to further increase thermal control of each.
