Two-phase stepper motor driver
120 - 220 VAC | STAC5 Applied Motion Products

The STAC5 series stepper drives are powerful, two-phase, bipolar step motor drives for high-speed, high-torque applications. With high bus voltage and high current output, STAC5 drives provide even the largest step motors with enough power to get the job done.

STAC5 stepper drives employ sophisticated current control designed for optimal smoothness over a wide speed range. Anti-resonance, torque ripple smoothing, and microstepping work together to bring step motor performance to a new high.

Power to the STAC5 drives comes from 120 or 220 volts AC (single-phase). To complement the STAC5 drives Applied Motion offers a specially matched set of low-loss NEMA 23 and 34 frame motors, all specifically designed with high voltage operation in mind.

The STAC5-120 drives operate on 120 VAC and output up to 5.0 A/phase (peak-of-sine) to the step motor. The STAC5-220 drives operate on 220 VAC and output up to 2.55 A/phase (peak-of-sine). Protection features like over-voltage, over-temperature, and over-current prevent damage to STAC5 drives while running in adverse conditions.
