B&R 8LSAA2.D8045S100-3 400VAC 4500RPM 1.27Nm Servo Motor EnDat Keyed Shaft

The B&R 8LSAA2.D8045S100-3 is a compact 400 VAC synchronous servo motor for machine axes that require single-turn absolute feedback and a keyed shaft connection.

This model operates at 4500 rpm nominal speed and provides 1.270 Nm nominal torque. The 14 mm keyed shaft is suitable for couplings, timing-belt pulleys, small gearbox inputs, and other mechanical transmission parts where positive torque transfer is required.

The ECI 1119 FS EnDat 2.2 single-turn encoder provides position feedback for compatible servo drive systems. This configuration is suitable for machines that use a defined reference process during startup and do not require multi-turn absolute position storage.

This S100 version does not include a holding brake. It is better suited to horizontal axes, supported rotary mechanisms, feeders, and compact positioning units where the motor shaft does not need to be mechanically held after power removal.

This product is a synchronous servo motor only. It should not be described as a power supply motor, internal I/O module, X2X Link device, PLC, servo drive, or bus component.
