3.54 in. (90 mm) Closed Loop Stepper Motor
The AR Series stepper motor adopts our AlphaStep technology closed loop control so the motor does not lose synchronism even when subjected to abrupt load fluctuation or acceleration. Requires AlphaStep AR Series (DC Input) Driver.
- Driver sold separately
- Designed for continuous operation
- Lower heat generation
- Low vibration
- High response
- No hunting
- No gain tuning
