The ELAU SM-140/20/210/P0/45/S1/B0 is a large-frame PacDrive synchronous servo motor designed for applications requiring stable low-speed operation, high torque output, and accurate motion control under heavy mechanical loads.

Different from the SM-140/30 series motors optimized for higher rotational speed, this model uses a 2000 rpm low-speed configuration, providing smoother operation and improved control capability for large inertia loads and applications requiring controlled acceleration.

With a 140 mm flange size and 21 Nm rated torque, the motor delivers strong continuous torque performance while maintaining precise positioning through its integrated SinCos single-turn encoder feedback system.

The P0 smooth shaft design provides flexible mechanical coupling options and is suitable for applications using direct couplings or clamp-type mechanical connections.

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

The B0 configuration means no holding brake is included, making this motor suitable for horizontal-axis applications where mechanical holding after power interruption is not required.

Compared with the SM-140/30/290 and SM-140/30/370 models, the SM-140/20/210 focuses on controlled low-speed motion, stable torque output, and large-load positioning rather than maximum speed.

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