Stepper motors are precision control motors that operate in fixed angular increments (steps). Each pulse signal received causes the motor to rotate by a precise angle, making them ideal for open-loop control applications requiring accurate positioning without cumulative error.
Subdivision technology divides the motor's inherent step angle into smaller increments, significantly improving control precision, reducing vibration, and enhancing overall performance.
- Enhanced step uniformity and control accuracy
- Significant reduction in motor vibration and low-frequency oscillation
- Improved torque output with reduced ripple
- Check direction signal strength and wiring polarity
- Verify signal voltage compatibility
- Ensure pulse mode matches driver configuration
