Introduction:

MD556 is a high performance microstepping driver using pure-sinusoidal wave current control technology, it is particularly suitable for applications desired with extremely low noise and low heating. Currently most of the microstepping drivers in the market apply pseudo-sinusoidal current control technology, which makes the output current to be a distorted sine wave, or makes much current ripple, both cause the motor higher noise and bigger vibration, furthermore cause serious motor heating, so when the motor works long time, the torque decrease, motor aging and the use life shorted. However the pure-sinusoidal precise current control technology (domestic patented technology) applied by MD556 can improve above problems very well, and the operating effect of the stepping motor is somehow inclined to that of servo motor.

Applications:

Suitable for a wide range of stepping motors of NEMA 17, 23 and 34, and usable for various kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices. Particularly useful in applications with extremely low noise and low vibration, high speed and high precision are desired.
