The WM850 series of high-performance interpolator drivers are suitable for driving 2-phase, 4-phase hybrid stepper motors (5.0A). Due to the use of advanced bipolar DC chopper technology, this series of drivers can make the same motor output power higher and faster than L/R type drivers. Its current control technology allows precise control of the coil current with less current ripple and less motor heating than similar products on the market.
