Product Description
Guanhong offers 2-phase and 3-phase stepper motors and stepper drivers for Nema 17, 23, 34, 42 and 43 series, using the latest DSP-based stepper control technology with many advanced features. The high-performance digital stepper drivers feature ultra-low noise, very low motor heating and ultra-smooth motor motion at low speeds.
The closed-loop stepper driver is a new type of simple servo motor driver developed by SZGH. It adopts a new dedicated motor control DSP core and applies vector closed-loop control technology. It successfully solves the problem of step loss of ordinary stepper motors, improves the high speed of the motor, reduces the heat and vibration of the motor body, and thus improves the feed speed and accuracy of the machine.
