It uses angled connector hardware, has a rated speed of 3000 rpm, and employs inductive EnDat encoder technology. The motor is self-cooled through free circulation and comes with a smooth shaft and multi-turn capability of 4096 revolutions.
Internal Product Review
The 8LSA44.EB030D000-3 is a B & R Automation three-phase synchronous motor with self-cooling by free circulation. Inductive EnDat 2.1 feedback and 19/12 single-/multi-turn bit resolution support precise positioning and stable motion performance. A rated speed of 3000 rpm makes the motor a strong choice for responsive servo applications.

Product Description:
The 8LSA44.EB030D000-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. Internally, it carries the 8LSA designation and follows the standard configuration that omits reinforced bearings. Length code 4 indicates the stack length, while product revision 3 marks the manufacturing update level. A mounting flange is provided for direct machine integration, letting the motor serve as a servo axis in packaging lines, pick-and-place arms, or other automation stages that demand electronically commutated torque and consistent positioning accuracy.
During operation, the motor attains a nominal speed of 3000 rpm, allowing it to drive medium-speed screws or belts without additional gear reduction. Thermal management relies on self-cooling with free air circulation, so unobstructed airflow is necessary once the housing is installed. The square mounting interface measures 100 mm across the flange, providing a consistent mounting footprint for compatible gearheads. Cabling exits through an angled, swiveling outlet that houses a fixed connector shell, simplifying routing inside tight cabinets while allowing quick disconnection for service. Position feedback is supplied by an inductive EnDat encoder, which resists contamination better than optical devices. An external oil seal is not included, so exposure to coolant spray must be avoided.
The encoder operates with version 2.1 signaling and delivers a combined single-turn and multi-turn resolution of 19/12 bits, while an internal counter tracks up to 4,096 revolutions without batteries. Because the motor has no holding brake, drive torque or mechanical clamps must maintain position during power loss. Torque is transmitted through a smooth shaft, eliminating keyway stress and supporting backlash-free collet hubs.
