8LSA26.E5060D200-3 by B & R Automation

The 8LSA26.E5060D200-3 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. It converts electrical energy from AC servo drives into mechanical rotation for indexing tables, pick-and-place axes, and conveyor sections in automated assembly and packaging lines. The 8LSA designation emphasizes compact size and high-speed output rather than high bearing load capacity, so the motor is suited for light- to medium-duty motion stages.

The motor attains a rated speed of 6000 rpm, enabling rapid cycle programs when paired with a compatible inverter. It uses a mounting flange dimension of 58 mm for the interface to machine frames, while an angled swivel outlet routes the power and feedback leads through a connector for strain-relieved assembly. Position feedback is delivered by an optical EnDat system in version 2.1, and a native resolution of 13/12 bits for single-turn and multi-turn operation supports fine interpolation for electronic gearing. The smooth shaft end simplifies coupling to precision gearheads, and length code 6 refers to the stator stack depth used for the required torque constant. This configuration uses standard bearing support rather than a reinforced bearing, and revision 3 marks the current electrical and mechanical update.

Thermal regulation relies on self-cooling with free air circulation, so no external fan or liquid jacket is required when the motor runs within its permissible load range. A standard holding brake is integrated to keep the driven axis stationary during power-off or emergency-stop events, and the brake supply conductors share the same termination. Because the motor has no oil seal, the shaft region should be kept away from pressurized fluids or abrasive contaminants. For absolute position retention, the encoder maintains a multi-turn counter that records up to 4096 revs, allowing the controller to resume motion immediately after restart without a homing sequence.
