HBS86H Closed-Loop Servo Motor Driver DSP 200KHz | NEMA 34
HBS86H Two-Phase Closed-Loop Servo Motor Driver with DSP Chip & 200KHz Vector Control
The HBS86H Servo Motor Driver is a next-generation, two-phase closed-loop driver engineered for precision automation. Powered by a dedicated DSP motor control chip and advanced vector closed-loop control technology, it eliminates the step-loss issues common to open-loop stepper systems — delivering higher speed performance, lower operating temperatures, reduced vibration, and dramatically improved machine accuracy. At roughly 50% of the cost of a traditional AC servo system, the HBS86H is the smart upgrade for CNC and automation professionals.
Made in Mainland China.

Frequently Asked Questions
Q: What makes the HBS86H closed-loop driver different from a standard open-loop stepper driver?
A: Unlike conventional open-loop stepper drivers, the HBS86H uses vector closed-loop control with a DSP chip to continuously monitor and correct motor position. This eliminates missed steps, reduces motor heat buildup, lowers vibration, and delivers more consistent accuracy — especially at high speeds. It effectively bridges the gap between budget stepper systems and costly AC servo systems.
Q: Is the HBS86H compatible with my existing 86-series stepper motor?
A: Yes. The HBS86H is fully mechanically and electrically compatible with standard 86-frame (NEMA 34) series stepper and servo motors, making it a straightforward drop-in upgrade for existing stepper drive setups without requiring new motor hardware.
Q: What subdivision (micro-stepping) settings are available on the HBS86H?
A: The HBS86H supports a wide subdivision range from 200 to 51,200 steps per revolution, which allows fine-tuning of motion smoothness and resolution to match the precision demands of your specific application — whether that's a CNC router, laser engraver, or automated assembly line.
Q: What protections does the HBS86H driver include?
A: The driver features built-in overcurrent protection, overvoltage protection, and tracking error protection. In the event of a continuous overload condition, the driver outputs an alarm signal — providing the same level of reliability typically associated with full AC servo systems.
