The ELAU SM-140/30/290/P0/45/S1/B0 is a high-torque PacDrive synchronous servo motor designed for demanding industrial automation applications requiring powerful acceleration, stable torque output, and precise closed-loop motion control.

Compared with the SM-100 series motors, this model features a larger SM-140 frame size, providing significantly higher torque capability for heavy mechanical loads and high-inertia applications.

With a rated speed of 3000 rpm and approximately 29 Nm rated torque, the SM-140/30/290/P0/45/S1/B0 delivers a strong balance between dynamic response and load capacity. It is designed for machines where higher mechanical force is required compared with compact servo motors.

The motor uses a P0 smooth shaft design, allowing flexible mechanical coupling solutions. The smooth shaft configuration is suitable for applications using clamp couplings or other direct transmission methods where a keyed shaft is not required.

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

The B0 configuration indicates no holding brake, making this version suitable for horizontal-axis applications where mechanical holding after power-off is not required.

The SM-140/30/290/P0/45/S1/B0 is commonly used in large packaging machines, material handling systems, printing equipment, and high-load automation platforms requiring reliable servo performance.

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

Installation Notes

Before installation, confirm the complete motor configuration:

SM-140/30/290/P0/45/S1/B0

Verify:

Motor flange size

Shaft design

Encoder type

Servo drive compatibility

Motor cable

Feedback cable

Mechanical coupling

This model uses a P0 smooth shaft.

Do not replace it directly with a smaller SM-100 motor because the torque, current rating, mechanical dimensions, and drive parameters are different.

Before commissioning:

Check encoder recognition

Verify motor rotation direction

Set servo parameters

Check position feedback

Perform reference movement

Confirm torque response
