1. A modular control system for an AC motor, comprising:
- a drive module housing an AC drive, the AC drive interconnecting the AC motor to a utility power source;
a control module housing a control structure for controlling operation of the AC drive;
a redundant power supply operatively connected to the control structure for supplying electrical power to the control structure; and
an intermediate module interconnecting the control module and the drive module so as to electrically couple the control structure and the AC drive.

Abstract
A modular control system for an AC motor is provided. The modular control system includes a drive module, a control module, and an intermediate module therebetween. The drive module houses an AC drive that interconnects an AC motor to a utility power source. Control structure for controlling operation of the AC drive is provided in the control module. The control structure and the control module and AC drive in the drive module are electrically coupled through the intermediate module.
