8LSA43.ee045ffgg-3 by B & R Automation

The 8LSA43.ee045ffgg-3 is a motor produced by B&R Automation and assigned to the 8LS Synchronous Motors series. This three-phase permanent-magnet unit serves as the rotary element in servo axes that require repeatable positioning and stable velocity control. In automated equipment, the motor converts regulated current from a drive amplifier into mechanical motion so conveyor sections, indexing tables, and pick-and-place heads can follow commanded paths with consistent response. That behavior helps the axis track short move profiles and settle quickly under varying load conditions.

All power, signal, and encoder conductors terminate on a compact connector, which keeps cabling organized and maintains shield continuity at the motor interface. Thermal energy is removed by self-cooling through free circulation, so air must move freely around the housing during operation. This arrangement also avoids the added complexity of external cooling hardware on the motor body. The stator face uses a mounting flange with a frontal dimension of 100 mm, allowing the motor to fit machine interfaces built for that flange size. The motor has a rated speed of 4500 rpm, which supports fast indexing and other high-response servo movement when the connected load stays within the drive system limits.

The motor carries the 8LSA designation, which identifies a specific configuration within the series. It uses a three-phase synchronous design, so commutation is handled electronically by the associated AC drive rather than by brushes or mechanical switching. This layout is intended for use with servo electronics that manage rotor angle, current phasing, and thermal supervision in real time. The housing uses length code 3, indicating the selected body length for this model. The unit is built to product revision 3, which corresponds to the configured option set used with this motor.
