Product Description:

The 8LSA55.EA022D000-3 is a rotary motor produced by B&R Automation and supplied under the 8LS Synchronous Motors series. Designed for controlled motion, the unit delivers torque and speed to automated axes in packaging, material-handling, and assembly machinery. The internal designation 8LSA indicates a standard configuration without reinforced bearings, and product revision 3 identifies the third mechanical iteration. A dedicated mounting flange and a length code of 5 establish the motor's overall stack depth and installation envelope.

The electrical topology is three-phase synchronous, so stator currents remain coordinated with rotor position for high dynamic stiffness. The motor has a rated speed of 2200 rpm for its nominal operating point. The flange circle measures 142 mm, allowing direct coupling to gearboxes or frames that use this metric size. Position feedback relies on an inductive EnDat sensor, and protocol version EnDat 2.1 provides digital communication with the drive while avoiding optical components. Self-cooling through free air circulation removes winding heat without forced air or liquid cooling.

Power and feedback lines exit through an angled swivel connection that mates with a standardized industrial connector. Its adjustable orientation helps reduce cable bend stress near panel walls or adjacent machine components. A smooth shaft transmits torque without keyways and accommodates clamp couplings or backlash-free hub assemblies. The encoder provides 19/0-bit resolution, and the device supports a single-turn count for absolute position feedback within one mechanical revolution. The motor has no holding brake and no oil seal, so external clamping or a suitable environmental barrier must be provided when the application requires them.
