Introduction:
M415B is a very small size high performance microstepping driver based on one of the most advanced technologies in the world today. It is suitable for driving any 2-phase and 4-phase hybrid stepping motors. By using advanced bipolar constant-current chopping technique, it can output more speed and power from the same motor, compared with traditional technologies such as L/R drivers. |
Applications:
Suitable for a wide range of stepping motors of size Nema 16, 17 and 23, and usable for various kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices. Extremely suitable for applications which expected to be low vibration, high speed and high precision.
