8LSN45.EA030D000-0 by B & R Automation

The 8LSN45.EA030D000-0 is a three-phase synchronous motor produced by B&R Automation and belongs to the 8LS Synchronous Motors series. It converts output from ACOPOS inverters into controlled rotary motion for positioning tasks and speed-regulated machine axes. The motor is supplied in a standard configuration, which makes it suitable for packaging equipment, material-handling systems, and light machining applications where compact servo performance is required. Its general-purpose layout also allows it to fit machines that need accurate motion without a specialized motor build.

Its rated operating speed of 3000 rpm indicates the motor's nominal running speed under standard electrical conditions. Heat is removed by a self-cooling design, so no separate blower is required during normal operation. The square face uses a 100 mm flange pattern, which supports direct installation on compatible brackets and gear units. Position feedback is provided by an Inductive EnDat sensor, and communication uses EnDat 2.1 for digital position transfer and electronic data exchange with the drive. The encoder is single-turn, so the system reads absolute position within one shaft revolution and relies on the machine control for position tracking beyond that range.

Cabling exits through an angled swivel connection, which helps route wires cleanly when clearance is limited around the back of the motor. The output shaft is a smooth shaft, supporting clamp-style couplings that help reduce backlash in precision motion systems. Overall body length corresponds to code 5, which keeps the housing compact enough for machine sections with limited installation depth. The unit mounts by a mounting flange for direct attachment to the driven assembly. Because it is supplied without a holding brake and without an oil seal, any standstill holding function or additional sealing must be provided elsewhere in the machine where those features are needed.
