8LSA44.R0045D000-0 by B & R Automation

The 8LSA44.R0045D000-0 synchronous servo motor is produced by B & R Automation within the 8LS Synchronous Motors series. This 8LSA standard configuration unit converts electrical energy into tightly controlled mechanical rotation. It supports precise positioning and speed regulation in packaging machines, small pick-and-place modules, and light-duty handling axes used throughout automated production cells.

The motor has a flange dimension of 100 mm, and its length code of 4 provides balanced rotor inertia for mid-range cycle times. A rated speed of 4500 rpm allows direct coupling to belts or gear stages without overspeeding the windings. Heat is removed by self-cooling by free circulation, so no external fan is required and cabinet airflow can be simplified. Position feedback is generated by a resolver, which withstands shock and ambient electrical noise while still giving rotor-angle information. Power and signal lines exit through an angled connection direction that can swivel, and quick-disconnect is provided by a molded connector housing. The motor uses standard bearings without reinforcement, has no holding brake, and is supplied without an oil seal, reducing passive drag on the shaft.

This motor uses a three-phase synchronous topology that delivers constant torque across the control range while keeping current harmonics low. Its internal mechanics are manufactured to a positioning accuracy of 10 arcmin, supporting repetitive index moves without adding external encoders. Installation uses the integrated mounting flange, so the motor only requires pilot alignment and four mounting bolts. A smooth shaft enables backlash-free coupling with clamped hubs or press-fit pulleys, and the absence of additional seals or brakes can reduce passive friction in precision feeders or lightweight rotary actuators.
