The ELAU SM-100/40/080/P0/45/S1/B1 is a PacDrive SM series synchronous servo motor designed for high-load motion applications requiring both high torque performance and secure shaft holding during power-off conditions.

Compared with the brake-free version SM-100/40/080/P0/45/S1/B0, this model integrates a B1 electromagnetic holding brake, providing additional mechanical holding capability when the servo system is stopped or the power supply is interrupted.

With a 100 mm flange size, 4000 rpm rated speed, and 8.0 Nm rated torque, this motor delivers a balanced combination of dynamic response and high load capability. The motor is suitable for applications requiring frequent acceleration, precise positioning, and reliable load retention.

The P0 smooth shaft design provides flexible coupling options for mechanical systems using clamp couplings or other shaft connection methods. Compared with P1 keyed shaft versions, the smooth shaft allows easier installation flexibility in applications where a key connection is not required.

The integrated S1 SinCos single-turn encoder provides accurate position and speed feedback for closed-loop operation with ELAU PacDrive servo drives and controllers.

The B1 brake configuration makes this motor especially suitable for vertical axes, lifting systems, and machines where the load must remain fixed during emergency stops or power-off situations.

This product is a synchronous servo motor only. It requires a compatible ELAU PacDrive servo drive and controller system.
