8LSA44.EB030D000-0 by B & R Automation

The 8LSA44.EB030D000-0 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. Within motion control systems, it delivers torque and speed to machine axes that depend on accurate electronic commutation and position feedback. The 8LSA designation identifies the standard version without reinforced bearings, making the unit suitable for general-purpose automation assemblies that run on servo drives. Its synchronous design supports repeatable motion in packaging, transfer, and indexing applications where steady response is required across changing load conditions.

Performance values center on a rated speed of 3000 rpm, allowing the rotor to follow drive commands with minimal slip. Rotor position is reported by an inductive EnDat sensor that supports protocol level 2.1. This digital link provides 19/12 bits of single-turn and multi-turn resolution, and the encoder records up to 4096 revs so absolute position remains available after power is removed. The motor uses a 100 mm flange for mounting to machine structures or gear units. Length code 4 gives the stator the depth needed for the EB torque class while keeping the housing diameter in the standard range.

Heat is removed by self-cooling through free air circulation, so the motor operates without separate fans or liquid lines. Electrical connections are made through an angled swivel connector that can be rotated to suit cable routing around nearby machine members. The motor has no holding brake, so any load-holding function must be provided by external mechanics or by controlled drive torque at standstill. It also uses a smooth shaft, and the lack of an oil seal makes the unit better suited to dry installation areas where contaminants and fluids are limited. The standard bearing arrangement and flange-mounted form suit medium-duty servo axes in general machine automation.
