The ELAU SM-140/30/370/P0/45/S1/B0 is a high-torque PacDrive synchronous servo motor designed for demanding automation applications requiring maximum torque density, accurate positioning, and stable operation under heavy mechanical loads.

Compared with the SM-140/30/290/P0/45/S1/B0, this model provides a higher torque rating of 37 Nm, making it suitable for applications with larger inertia, heavier mechanical assemblies, and higher force requirements.

The SM-140 frame size provides increased mechanical strength and thermal capacity compared with the smaller SM-100 series. With a 3000 rpm rated speed and high torque output, the motor delivers strong acceleration capability while maintaining precise closed-loop motion control.

The motor uses a P0 smooth shaft configuration, providing flexible mechanical coupling options for applications using clamp couplings or other direct connection methods.

The integrated S1 SinCos single-turn encoder delivers accurate position and speed feedback, enabling precise synchronization with ELAU PacDrive servo drives and controllers.

The B0 configuration means no holding brake is included, making this version suitable for horizontal axes and applications where external mechanical locking is not required.

The SM-140/30/370/P0/45/S1/B0 is designed for large packaging machines, high-load automation equipment, material handling systems, and other industrial applications requiring powerful servo performance.

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