MOTOR CONTROLLER SYSTEM AND METHOD FOR MAXIMIZING ENERGY SAVINGS |
摘要 |
A motor controller and method for maximizing the energy savings in an AC induction motor at every load wherein the motor is calibrated at two or more load points to establish a control line, which is then programmed into a non-volatile memory (30) of the motor controller. A DSP-based closed-loop motor controller observes the motor parameters of the motor such as firing angle/duty cycles, voltage, current and phase angles to arrive at a minimum voltage necessary to operate the motor at any load along the control line. The motor controller performs closed-loop control to keep the motor running at a computed target control point, such that maximum energy savings are realized by reducing voltage through pulse width modulation. |

1. A system for controlling an AC induction motor to maximize energy savings compromising:
a means for connecting a motor controller to an AC induction motor; a means for placing a load on said AC induction motor; a means for removing a load from said AC induction motor; a means for sweeping a control space of the AC induction motor and taking measurements of operating parameters of the AC induction motor; a means for establishing a control line from said measurements; a means for storing said control line in said motor controller; a means for controlling said operating parameters; and a means for performing closed-loop control of said AC induction motor to keep the motor running in accordance with said control line. |
