product description

DM3922 is a newly launched digital three-phase stepper motor driver, using the latest 32-bit DSP technology, mainly driving 86, 110, 130 three-phase hybrid stepping motor. The micro-step is subdivided into 16 kinds, the maximum number of steps is 30000 steps/revolution; the working peak current range is 2.8A-10.0A, and there are 8 kinds of output currents, which can meet the application needs of most occasions. Due to the use of built-in micro-segmentation technology, even under the condition of low-segmentation, the effect of high-segmentation can be achieved, running smoothly at low, medium and high speeds with low noise. With half-current, over-voltage, over-current and other protection circuits. The drive has integrated parameter auto-tuning function, which can automatically generate optimal operating parameters for different motors and maximize the performance of the motor. The driver is AC power supply, and the recommended working range is AC110V-220V.Features1. Brand new 32-bit DSP technology.2. The motor has low vibration, low power consumption and low noise.3.
