Ideal Motor for CNC machines and other machinery. Standard NEMA 34 frame size. 85Kgcm bipolar configuration motor with LEADSHINE original D860H | MA860H STEPPER DRIVER 7.2A. Ideal performance at 5Amp configuration.

The D860H | MA860H is a high performance Leadshine original microstepping drive based on pure-sinusoidal current control technology. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drives on the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.
