1. Introduction, Features and Applications
Introduction
The M415B is a very small size high performance microstepping driver based on one of the most
advanced technologies in the world today. It
’
s 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 drivers such as L/R
drivers.

Applications
Suitable for a wide range of stepping motors from NEMA size 14 to 23, which used in various kinds
of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, pick-place
devices, and etc. It
’
s specially adapted to the applications desired with low vibration, high speed and
high precision.
