8LSN44.EB030D900-0 by B & R Automation

The 8LSN44.EB030D900-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. Designed as a compact drive element, it converts electrical energy into torque for precise positioning and speed control on automated axes, conveyors, and pick-and-place gantries. Its mechanical interface and integrated feedback allow it to fit directly into standardized machine frames and communicate with servo drives in industrial automation. This arrangement supports closed-loop motion tasks that require repeatable acceleration and stable speed regulation.

The motor attaches to machinery through a flange pattern with a diameter of 100 mm, which supports repeatable alignment at the machine interface. During continuous operation, it reaches a rated shaft speed of 3000 rpm, giving motion systems a balance between torque density and linear throughput. The motor uses a self-cooling design with an increased mass moment of inertia. This allows operation without an external blower or liquid circuit, and the added rotor inertia can help smooth speed changes. Position feedback is supplied by an inductive EnDat sensor that resists contamination and supports digital diagnostics. This transducer operates with protocol version 2.1 to stream position, velocity, and status data to the controller.

Cabling exits the housing through an angled swivel interface, allowing radius-limited power and feedback leads to clear adjacent components. A factory-installed standard holding brake locks the shaft when power is removed, which protects suspended loads and prevents drift at standstill. The absolute encoder provides multi-turn 4096 revs capacity and 19/12 bits of single-turn and multi-turn resolution, enabling startup without homing routines. The motor is supplied with a mounting flange and includes an oil seal to limit lubricant ingress. It also carries length code 4 and uses a keyed shaft to transmit torque to couplings or pulleys.
