8LSN44.EB030D700-0 by B & R Automation

The 8LSN44.EB030D700-0 is a three-phase synchronous motor manufactured by B&R Automation within the 8LS Synchronous Motors series. The 8LSN designation places the unit in a motor platform used for direct rotary actuation on positioning and speed-regulated axes in automated machinery. Through its standard configuration and integral mounting flange, the motor serves as the drive element that couples controlled motion to conveyor sections, gantry joints, indexing tables, and similar machine assemblies.

A flange dimension of 100 mm fixes the stator to machine frames while maintaining concentricity between the housing and load. At a rated speed of 3000 rpm, the rotor delivers steady velocity when the drive inverter supplies nominal frequency, supporting mid-range motion profiles common to material-handling equipment. The cooling principle is self-cooling, so heat is carried away through the housing without external fans. Position feedback relies on an Inductive EnDat sensor, which is less sensitive to contamination than optical systems. The feedback cable exits through an interface in an angled (swivel) direction, helping cable routing in compact control cabinets.

The encoder furnishes 19/12 single-turn and multi-turn bits, giving fine resolution for incremental moves while tracking absolute position over up to 4096 revs of shaft rotation. Communication follows EnDat version 2.1, allowing bidirectional parameter exchange with compatible drive controllers. An oil seal at the shaft opening limits lubricant migration into the stator cavity. The design omits a holding brake, so static torque must be supplied by the drive or by external locking devices. Length code 4 indicates a medium active stack that balances torque density against overall size, and the keyed shaft end supports rigid coupling to pulleys or gearboxes.
