PORTABLE MOTOR DRIVE SYSTEM
First Claim
1. A drive system comprising:
- a user interface enabling a user to select an operating frequency set point and an operating voltage set point, the operating frequency set point being selected from a range of frequency set points and the operating voltage set point being selected from a range of voltage set points;
a variable speed drive configured to drive a motor at the selected operating frequency set point and selected operating voltage set point; and
a controller configured to receive input from the user interface and control the operating frequency and operating voltage of the variable speed drive.

Abstract
Systems and methods for driving a motor are provided. One implementation of a drive system comprises a user interface, a variable speed drive, and a controller. The user interface enables a user to select an operating frequency set point and an operating voltage set point. The operating frequency set point is selected from a range of frequency set points and the operating voltage set point is selected from a range of voltage set points. The variable speed drive is configured to drive a motor at the selected operating frequency set point and selected operating voltage set point. The controller is configured to receive input from the user interface and control the operating frequency and operating voltage of the variable speed drive.
