Stepper Motor Drivers

Deliver Quiet, Efficient and Smooth Motion

Allegro offers a complete lineup of stepper motor drivers for office automation, industrial, and automotive applications.

Our advanced technologies based on proprietary algorithms, QuietStepTM , minimizes noise and vibration in stepper motor designs by reducing torque ripple and current distortion. QuietStep adjusts on-the-fly the amount of fast decay during a PWM cycle to keep current ripple at a low level over the various operating conditions. This adaptive feature improves performance of the system resulting in reduced audible motor noise, reduced vibration, and increased step accuracy.
