Applied Motion Announces STRAC2, STRAC8 Stepper Drives

Applied Motion Products expands its family of STR Stepper Drives with two AC-powered units for use in industrial applications powered by AC supply voltages. The STRAC Stepper Drives bring motion control to basic step and direction applications.  Units are designed for larger motors and applications requiring maximum power.

Like their DC-powered counterparts, STRAC Stepper Drives feature microstepping performance and current control with anti-resonance. Units operate on AC supply voltages of 90 to 240 VAC and wire directly to 120 or 220 VAC line voltages to eliminate DC power supply requirements. The drives internally convert AC line voltages to high DC bus voltages to drive large step motors.

Available in two models, the STRAC2 provides up to 2.2 A/phase while the STRAC8 provides up to 8.0 A/phase. Every stepper drive in the STR Series operates in step & direction or pulse/pulse control mode. Selecting between the two modes is simple by moving a jumper located under the drive cover or via dip switch on the front panel. Each drive microsteps to 25,000 steps/rev with a 1.8° step motor (1/125 step) even when command pulses are low resolution.  Users can set up drive parameters – including motor selection, current, and step resolution – using dip or rotary switches. No software is required.

STRAC Stepper Drives are UL Recognized, CE certified, and RoHS compliant. Applied Motion Products offers NEMA 23 and 34 frame step motors optimized for use with these AC-powered drives.
