The ELAU SM-100/40/080/P0/45/S1/B0 is a high-torque PacDrive synchronous servo motor designed for industrial motion applications requiring strong load capability, accurate positioning, and reliable dynamic performance.

Different from the high-speed SM-100/50/030 models, this motor focuses on higher torque output with an 8.0 Nm rated torque and 30 Nm peak torque capability. The 4000 rpm rated speed provides a balanced combination of speed and mechanical force, making it suitable for machines that require stable acceleration and continuous torque performance.

The motor features a 100 mm frame size and a P0 smooth shaft configuration. The smooth shaft design provides flexibility for mechanical coupling solutions where a keyway connection is not required.

The integrated S1 SinCos single-turn encoder provides precise position and speed feedback for closed-loop control with ELAU PacDrive servo systems. The B0 configuration indicates that this motor is supplied without a holding brake.

Designed for use with PacDrive controllers and servo drives, the SM-100/40/080/P0/45/S1/B0 is commonly applied in packaging machinery, assembly systems, and automated production equipment requiring reliable multi-axis synchronization.

This product is a synchronous servo motor only. It should not be described as a servo drive, motion controller, inverter, PLC module, or power supply.
