Product Description:
The 8LSA34.E1030D100-0 synchronous servo motor is produced by B&R Automation as part of the 8LS Synchronous Motors series. It converts drive-inverter output into precise mechanical rotation for positioning tasks in automated machinery, conveyors, and packaging axes. The model follows the 8LSA configuration and is intended for installation on machine frames where accurate motion and integrated feedback are required. Its synchronous operating principle supports controlled torque, speed, and position when the motor is paired with a compatible servo drive.
The motor has a length code 4 housing and reaches a rated shaft speed of 3000 rpm, providing a suitable velocity range for mid-sized tool heads. Heat is removed through self-cooling with free air circulation, so no external fan or liquid-cooling jacket is required. A square flange measuring 91.3 mm supports accurate alignment with modular gearboxes while retaining a compact footprint. Position feedback is generated by an optical EnDat encoder that uses protocol revision 2.1, enabling automatic parameter transfer to the connected drive. Feedback resolution is 13/12 bits for single-turn and multi-turn position data, respectively, supporting precise closed-loop control. The shaft has a keyed end that provides positive engagement with a compatible coupling, pulley, or gearbox input. Power and feedback signals connect through the motor’s stator-mounted interface.
Extended position tracking is available because the encoder records up to 4096 revolutions of multi-turn data before the count cycles. Cable routing is aided by the angled swivel plug, which allows the connector direction to be adjusted so cables remain clear of nearby moving structures. The three-phase synchronous design uses permanent magnets in the rotor to provide responsive torque under vector control. The motor includes a standard bearing set without reinforcement and is supplied with no holding brake, so an external mechanism or drive-applied torque must retain static loads when required. An oil seal is not installed, making the motor best suited to applications where the shaft interface is not exposed to oil or similar fluids.
