This nema 14 stepper motor driver uses the best dedicated motor control DSP chip and vector closed-loop control technology to completely overcome the problem of open-loop stepper motor lost. At the same time, it significantly improves the high-speed performance of the motor, reduces motor heating and reduces motor vibration, improves machine processing speed and accuracy, and reduces machine energy consumption. In addition, it also has protection functions such as overvoltage, overcurrent, and tracking error.

Steps / rev
1. The high-quality motor steel sheet has small self-inductance reactance and good responsiveness. It can run at low speed directly with the load link in the near-blocking state without gear reduction, so it can generate a high torque-to-inertia ratio on a large load shaft and eliminate the systematic error caused by the use of the reduction gear.
2. The internal rotor is exquisitely crafted, and its surface has a rotor glue to prevent burrs on the surface of the carbon steel after oxidative grinding to increase the motor noise.
3. The whole body is made of high-strength metal, which is firm and durable.
4. This nema 14 stepper motor driver can control the angular displacement by controlling the number of pulses to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency to achieve the purpose of speed regulation and positioning.
