New Advances In Pulse Width Modulated Slip Power Recovery Drives For Pumps
Abstract
Since its invention by Nikola Tesla in 1888, the alternating-current (AC) motor has been a critical driver for the industrial age. One of his original three patents was the wound rotor induction motor (WRIM). Later, Westinghouse refined the design of the wound rotor motor to permit control of the speedtorque characteristics of the machine. This paper discusses a new advancement in Pulse Width Modulated slip power recovery drives (PWM-SPR) application for pumps. By using sophisticated adjustable speed drive control, a significant amount of slip power can be fed back to the utility line, hence resulting in energy savings. Also, application examples are discussed to enhance understanding.
