The Leadshine HBS86H closed-loop stepper motor driver is a device that is used to control the movement of a stepper motor, which is a type of electric motor that moves in discrete steps rather than smoothly. The HBS86H driver is designed to work with 2-phase stepper motors and operates on a voltage range of 20-70VAC. It has a maximum current output of 8A and is designed for use in closed-loop control systems, which means that it can accurately control the position and speed of the motor based on feedback from an encoder or other sensor. The HBS86H driver is commonly used in a variety of applications, including manufacturing, robotics, and automation. It is an important component of a CNC (Computer Numerical Control) system, which is used to control the operation of machine tools such as lathes and milling machines.
1. Closed-loop, eliminates loss of synchronization
2. Broader operating range – higher torque and higher speed
3. Reduced motor heating and more efficient
4. Smooth motion and super-low motor noise
5. Do not need a high torque margin
6. No Tuning and always stable
7. Fast response, no delay, and almost no settlement time
8. High torque at starting and low speed, high stiffness at standstill
9. Lower cost
The HBS series offers an alternative for applications requiring high performance and high reliability when the servo was the only choice, while it remains cost-effective. The system includes a 2-phase stepper motor combined with a fully digital, high-performance drive and an internal encoder which is used to close the position, velocity, and current loops in real-time, just like servo systems. It combines the best of servo and stepper motor technologies, and delivers unique capabilities and enhancements over both, while at a fraction of the cost of a servo system.
HBS86H uses dedicated motor control DSP chip and application vector closed-loop control technology to overcome the problem of open-loop stepper motor loss, the impulse response frequency can reach 200 kHz; input power C C: 16-70VAC, DC24-100vdc
