8LSN54.E3030D000-0 by B & R Automation

The 8LSN54.E3030D000-0 is a servomotor produced by B&R Automation within the 8LS Synchronous Motors series. It is a permanent-magnet unit intended for closed-loop positioning, speed, and torque tasks on gantries, conveyors, and packaging axes where compact drives must fit directly on the machine frame. By integrating with the ACOPOS drive platform, the motor supplies feedback-ready rotary motion that can be synchronized with PLC sequences in real time.

The mechanical interface uses a mounting flange, allowing the housing to bolt directly to a gearbox or machine plate without additional brackets. Power and feedback conductors exit through an angled (swivel) connection, so cables can be routed parallel to the machine wall and relieved of strain during articulation. Thermal management relies on a self-cooling principle, so the motor dissipates heat through its surface without external air or liquid circuits. The faceplate spans 142 mm, which matches standardized IEC machine layouts and provides the bolt circle for attachment. During operation, the rotor reaches a rated speed of 3000 rpm, providing a balance between torque density and dynamic response in medium-performance applications.

This device ships in a standard configuration, so the winding, feedback, and connector codings follow the default selections for this model. The housing uses length code 4, which provides added coil depth for higher continuous torque without enlarging the flange width. It has a three-phase synchronous design and produces sinusoidal back-EMF that pairs with vector-controlled inverters for smooth current regulation. The shaft is supplied as a smooth shaft, enabling backlash-free force transmission through clamp or shrink-disk couplings. The motor is delivered without a holding brake and has no shaft seal, so external measures are required if static locking or fluid exclusion is needed.
