Product Description:
The 8LSA34.EB022D000-0 is a three-phase synchronous servo motor produced by B&R Automation for its 8LS Synchronous Motors series. It supplies controlled rotary motion for positioning axes in packaging equipment, gantry systems, and other industrial machinery that require accurate and repeatable speed profiles. The internal “8LSA” designation indicates standard construction without reinforced bearings, while the motor is designed to operate with compatible B&R servo drives. This arrangement supports closed-loop control of speed, torque, and position in automated machinery.
Under nominal drive settings, the motor reaches a rated speed of 2,200 rpm. Rotor position is measured by an inductive EnDat encoder that communicates through protocol version 2.1. It returns absolute position data with 19 bits for single-turn position and 12 bits for multi-turn position. The encoder tracks absolute position across 4,096 revolutions, allowing the axis to retain its reference state after a power cycle without requiring a new homing sequence. Motor length code 4 indicates the active stack depth used for this configuration.
A mounting flange with a centering diameter of 91.3 mm aligns the motor with the machine and transfers reaction forces into the supporting frame. Power and feedback leads exit through an angled swivel connector, allowing the cable direction to be adjusted for the available installation space. The molded connector housing keeps the electrical interfaces compact and helps protect the cable terminations. Thermal management relies on self-cooling through free air circulation, eliminating the need for auxiliary fans or liquid coolant loops. Mechanical output is transmitted through a smooth shaft that is suitable for clamping couplings or compatible gearheads. The motor has no holding brake, so an external brake or clamping device is required when a stationary load must remain secured after power is removed. The shaft does not include an oil seal, making separate sealing hardware necessary where the motor interface may be exposed to lubricant or other fluids.
