Product Description:

The 8LSA55.E3030D000-0 is a synchronous servo motor from B&R Automation in the 8LS Synchronous Motors series. It operates as a rotary actuator that converts drive current into controlled torque and speed for indexing tables, packaging axes, and similar automation equipment. When paired with ACOPOS drives through its coded power and feedback connection, the motor supports closed-loop motion control with accurate position and speed regulation. Its compact design suits machine layouts that need precise servo performance without separate cooling attachments.

The mechanical interface uses a mounting flange diameter of 142 mm, allowing the housing to seat directly against machine plates without adapter rings. During operation, the motor reaches a rated speed of 3000 rpm, which suits many direct-drive and geared axis arrangements. Heat is dissipated by self-cooling with free air circulation, so internal losses move into the frame and then into the surrounding air without forced-air accessories. Power and feedback cables connect through an angled swivel outlet that helps routing in tight spaces, and the motor uses a smooth shaft for backlash-free coupling with clamping hubs or shrink discs.

The motor uses length code 5, which indicates the axial housing length used for this frame size and supports continuous output suited to medium-frame automation tasks. It operates without a holding brake, so any required holding force at standstill must come from the drive or from external mechanical restraint. The electrical design is three-phase synchronous, allowing the servo drive to control commutation electronically across the normal speed range. At the front end, the motor has no oil seal, which reduces friction and is suitable where the machine arrangement does not require sealing against oil migration.
