AC Induction Motor Controllers
Kelly’s programmable AC induction motor controllers provide efficient, smooth and quiet controls for small and midsize electric vehicles, such as golf carts, go-carts, stacking cars, forklifts, hybrid vehicles and electric boats, as well as industrial motor speed control. It uses high power MOSFET’s and, SVPWM and FOC technology to achieve efficiencies of up to 99% in most cases. A powerful microprocessor brings in comprehensive and precise control to the controllers. It also allows users to adjust parameters, conduct tests, and obtain diagnostic information quickly and easily.
