8LSA65.EB045D000-3 by B & R Automation

The 8LSA65.EB045D000-3 belongs to the 8LS Synchronous Motors series from B&R Automation. It is a three-phase synchronous motor intended for positioning and speed-controlled axes in automated machinery, where the servo drive regulates torque, speed, and rotor position. The unit uses a standard 8LSA mechanical configuration with a mounting flange, giving machine builders a compact motor for transfer systems, packaging equipment, and other precision motion platforms. Integrated feedback allows the drive to monitor the rotor directly during operation and maintain accurate axis response. This helps the axis follow commanded motion profiles consistently.

The motor has a rated speed of 4500 rpm and uses self-cooling with free circulation, so forced ventilation is not required under nominal load. It mounts through a 190 mm flange, which supports direct attachment to a machine plate or gearbox input. Power and feedback cables exit through an angled swivel connector that simplifies routing where straight cable clearance is limited. Electrical termination uses a single connector, and the integrated feedback system uses inductive EnDat communication on the EnDat 2.1 protocol. This arrangement provides single-turn and multi-turn position data to the servo drive while keeping the motor interface compact.

The feedback supports multi-turn operation with 4096 revolutions, allowing startup without rehoming after every power cycle, and the encoder resolution is 19/12 bits for fine position interpolation. The motor has a smooth shaft, which suits backlash-free clamping couplings and similar hub connections, and it is marked as Revision 3. A length code of 5 indicates the housing depth used for this model. The configuration does not include a reinforced bearing or a holding brake, so any static load retention must come from the drive or an external locking device. It is also supplied without an oil seal, which suits installations where lubricant exclusion is not critical.
