A compact, microstepping chopper drive for stepper motors that provides a cost effective solution for production volumes. Its ease of integration and small physical size allows for quick integration into your design.

The Whisper Drive incorporates microstepping technology, a controller and runs off a single power supply. With eight microsteps per full step, the Whisper can smooth out cogging associated with stepper motors run in a full step mode. The drive has a mixed current decay mode for reduced resonance and improved microstepping. Microstepping also reduces audible noise in the motor. The Whisper can be used with all HSI linear and rotary motors from 20 mm to 46 mm diameters.
