B&R 8LSA44. EA030D000-3 permanent magnet synchronous servo motor
B&R 8LSA44. EA030D000-3 is a three-phase permanent magnet synchronous servo motor from B&R. Compatible with ACOPOS and ACOPOS P3 servo drives, it belongs to industrial standard servo motors.
Function: Receive servo drive output power, convert electrical energy into high-precision mechanical torque output; By relying on the built-in EnDat encoder to provide real-time feedback on position and speed, the device achieves position positioning, speed closed-loop, and torque control; The driving mechanism completes high-speed reciprocating, precise positioning, synchronous following motion, and is widely used in the motion axis of automation equipment to complete process actions such as machining, conveying, and positioning.

Product features
- Permanent magnet synchronous design, fast dynamic response, strong overload capacity, peak torque can reach 22.8Nm, suitable for frequent start stop, acceleration and deceleration conditions.
- Equipped with EA induction EnDat single loop absolute encoder, it has strong anti-interference ability, no need to return to zero when powered on, and high position feedback accuracy.
- Natural self cooling and heat dissipation, no need for additional cooling fans, simple overall structure, reducing equipment failure rate.
- Flange 100mm standard installation, optical axis output, rotatable and bendable connector, flexible wiring, adaptable to various mechanical installation structures.
- The protection level is IP65, and the flange and shaft end protection are reliable, which can adapt to industrial environments with workshop dust and a small amount of oil splashing.
- Perfectly matched with the full range of servo drives from B&R ACOPOS and ACOPOS P3, seamlessly integrated with the B&R PLC motion control architecture.
- No brake version, suitable for applications outside the vertical axis; If vertical load is required, a derivative model with a brake should be selected.
- The status of the motor body can be diagnosed by reading temperature, encoder faults, and other diagnostic information through the driver, which facilitates equipment maintenance and troubleshooting.
