If you specify or use variable speed drives and have been looking for a dependable ALTERNATIVE
to Variable Frequency Drives (VFD'S), PAYBACK drives are the clear choice. They provide efficient variable speed control and deliver the ultimate in reliability and performance without the complexity or high cost of ownership associated with VFD'S.
PAYBACK technology offers many exclusive advantages over VFD technology:
With the PAYBACK shaft mounted drive, there is no current harmonics or voltage distortion. Since the PAYBACK drive does not alter the frequency or voltage to the AC motor, there are absolutely no ac line polluting problems to begin with! Hence, you never need line chokes, filters, reactors, bypass disconnects or expensive isolation transformers.
PAYBACK drives are the leading choice for true retrofit capability because you can always use your existing motors and wiring.
There is never any need for expensive inverter duty motors, because PAYBACK drives allow standard ac motors to operate as originally intended, with pure uninterrupted ac power, and unlike VFD's, there is never any possibility of premature motor failure caused by motor winding insulation breakdown or micro-electro pitting of motor bearings.
