Product Description:

The 8LSA36.EA045D000-0 is a three-phase synchronous motor from B&R Automation and belongs to the 8LS Synchronous Motors series. It serves as a drive element for positioning or speed control in automated cells, packaging machinery, and material-handling gantries. This type of motor is commonly paired with a servo inverter to provide coordinated motion on indexing, transfer, and handling axes. The unit follows the 8LSA standard configuration, so it does not use a reinforced bearing. It also includes a field connector for straightforward electrical integration.

The mounting interface uses a 91.3 mm flange, allowing installation on IEC-conforming frames. A maximum speed of 4500 rpm sets the upper operating speed for the matched inverter. Position data comes from an Inductive EnDat encoder that uses protocol 2.1. Its resolution is 19/0, which indicates 19 single-turn bits and no multi-turn bits. High encoder resolution helps the control loop maintain smooth interpolation at low speed and accurate feedback during rapid moves. The motor does not have a reinforced bearing or a holding brake, so excessive axial load and static locking must be handled externally. Power and feedback share a molded connector, the motor uses flange mounting, and the housing comes without an oil seal. The encoder provides single-turn capability, and the three-phase synchronous design operates without slip.

Cooling uses a self-cooling, free circulation design, so air must move freely around the frame during operation. Cables exit through an angled (swivel) connector orientation, which helps reduce strain when routing leads in moving equipment. The swivel connector can be rotated to suit cable direction where harness movement changes during machine travel. The motor uses a smooth shaft, which suits clamp, collet, or shrink-fit couplings. Electromagnetic length code 6 gives the motor a compact active length for lightweight axes, while the open airflow path supports stable thermal behavior during continuous duty.
