The ELAU SM-100/40/050/P0/45/S1/B1 is a PacDrive synchronous servo motor designed for industrial automation applications requiring precise positioning and secure holding torque during machine downtime.

Different from the B0 brake-free versions, this model integrates a B1 electromagnetic holding brake, allowing the motor shaft to maintain its position when the servo system is powered down. This makes it particularly suitable for vertical axes, lifting mechanisms, and applications where load positioning must be preserved after emergency stops or power interruptions.

The motor features a 100 mm flange size, 4000 rpm rated speed, and 5.0 Nm rated torque, providing a balanced combination of speed and torque for general-purpose motion applications.

The P0 smooth shaft configuration provides flexible mechanical coupling options and is suitable for applications using clamp-type couplings or other shaft connection methods that do not require a keyway.

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

With its integrated brake function, compact design, and reliable feedback system, the SM-100/40/050/P0/45/S1/B1 is suitable for packaging machinery, assembly systems, material handling equipment, and other automated production systems.

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.
