8LSA57.E0022D100-0 by B & R Automation

B & R Automation manufactures the 8LSA57.E0022D100-0 three-phase synchronous motor within the 8LS Synchronous Motors series. The 8LSA designation identifies a standard build without reinforced bearings, and the frame uses length code 7 for this model size. In automated packaging lines, assembly stations, or material-handling gantries, the motor converts regulated armature current into precise rotation, allowing the machine controller to position loads quickly and maintain commanded speeds under feedback supervision during repeated production cycles.

The motor uses a flange measuring 142 mm, so machine frames with that pilot can accept the housing without adapter rings. A keyed shaft end secures torque transfer to couplings or timing pulleys without slippage during acceleration or deceleration. Nominal operating velocity reaches 2200 rpm, giving a balance between torque output and thermal limits for feeders or indexers. Heat is removed through self-cooling with free air circulation, eliminating external fans and simplifying enclosure design. Position feedback is generated by an optical EnDat encoder that follows version 2.1 protocol, and its digital word contains 13/0 bits, providing single-turn position data for closed-loop motion.

Installation suits integrated machinery layouts because the power and feedback leave the housing through an angled connection, and the pre-fitted connector lets wiring be completed without disassembling covers. The stator body carries a mounting flange, so axial alignment is maintained by the pilot surface during assembly, and cable routing remains compact around nearby machine members. Internal position tracking relies on a single-turn code disk, so absolute position is available within one revolution while extended counts are maintained in the controller. Because the design omits a holding brake and an oil seal, the motor is best suited for horizontal or clean-enclosure axes where back-driving forces and fluid ingress are not a concern.
