EM882S Stepper Drive

80VDC, 8.2A

As the next generation of MSD880 drive, the EM882S model is a new digital stepper drive based on Leadshine’s widely implemented DM stepper drives (10+ millions of units in field). While retaining features of simple design, easy setup, high precision and reliability, this drive is upgraded by adopting the latest stepper control technology and added additional advanced features for better torque (10-25%), quicker response time, control command smoothing, easy self-test, etc.

The EM882S is able to power 2-phase (1.8°) and 4-phase (0.9°) stepper motors smoothly with very low motor heating & noise. It can take 20-80VDC supply voltage and output 0.5 to 8.2A current. All the microstep, output current configurations and motor model selection can be easily done via built in DIP switches. Therefore, the EM882S is an ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 23, 24 and 34 stepper motors.

EM882S Stepper Drive Features

Typical Applications

The EM882S stepper drive is designed to power 2-phase (1.8°) or 4-phase (0.9°) NEMA23, 24 and 34 hybrid stepper motors. It can be adopted in many industries (CNC machinery, electronics, medical, automation, packaging…) for applications such as CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines, etc. Its excellent performance, simple design, and easy setup features make EM882S ideal for many step & direction control type applications.
