Portable motor drive system
First Claim
1. A drive system for operating a valve in an emergency situation, the drive system comprising:
- a portable housing;
a user interface configured to receive at least one user input;
a memory configured to store at least one operating frequency and at least one operating voltage for driving a valve motor of a valve, the valve motor and valve external to the portable housing;
a controller disposed within the portable housing, the controller configured to receive the at least one user input from the user interface and retrieve the at least one operating frequency and at least one operating voltage from the memory based on the received at least one user input;
a variable speed drive disposed within the portable housing, the variable speed drive configured to drive the valve motor for operating the valve, wherein the controller is configured to control the variable speed drive to drive the valve motor at the at least one operating frequency and at least one operating voltage, anda power supply disposed within the portable housing, the power supply providing power to the variable speed drive, wherein the power supply is a hybrid system including a battery pack having a high energy-to-weight ratio and at least one capacitor having a high power-to-weight ratio, wherein the battery pack is configured to supply power at a first power level and the at least one capacitor is configured to supply power at a second power level,wherein the controller is configured to control the power supply to supply power to the variable speed drive to drive the valve motor for operating the valve.

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.
