Technical Introduction

Failure of 8LSA45.EA030D100-3 disables the machine servo axis. The axis triggers drive alarm and stops motion; the B&R controller reports encoder, overheat or overcurrent faults, halting production on packaging machines, CNC equipment and automated handling systems. Loss of position feedback causes servo ready dropout and machine safety interlock activation.

The B&R 8LSA45.EA030D100-3 is a compact high power-density synchronous servo motor from B&R 8LS family. This model features a 45mm flange, rated speed of 3000 rpm and rated torque of 1.31 Nm with natural convection cooling. It uses EnDat 2.2 single-turn absolute encoder and supports OCT (One Cable Technology) hybrid single-cable connection combining power and position feedback in one cable, reducing machine wiring complexity. The motor has IP65 protection rating, F-class winding insulation and swivel angled rotatable connector for flexible cabinet routing. Low cogging torque delivers ultra-smooth positioning for high-precision motion tasks. Winding temperature monitoring, rotor position and motor health diagnostics are continuously transmitted back to ACOPOS servo drive and B&R PLC for alarm logging and machine status visualization. Widely used for packaging machinery, CNC machine axes, robotic gantries, printing lines and automated assembly equipment. Machine maintenance teams stock 8LSA45.EA030D100-3 to restore axis motion quickly during unexpected downtime.

• Best Suited For
  • B&R ACOPOS servo drive controlled machine axes, packaging, automation and machine tool positioning
  • High-precision 1.31Nm axis motion control at 3000rpm, single-cable OCT wiring
  • Direct drop-in replacement for existing B&R 8LSA45.EA030D100-3 8LS servo motor hardware

Core Technical Specifications

Field Engineer’s Tech Notes

• Confirm encoder type, shaft style, brake option and ACOPOS drive firmware compatibility before replacement; different suffix variants are not interchangeable.
• Lockout/tagout and servo power discharge required before disconnecting OCT hybrid cable connectors.
• Inspect single hybrid cable and pin contacts; damaged wiring is the common root cause of intermittent EnDat encoder communication faults.
• After replacement, set B&R motor parameter dataset, execute axis homing, tune ACOPOS current/speed/position control loops, test full axis travel range and verify encoder absolute position feedback before production run.
• ESD protection required while handling encoder connector and internal feedback components.
• Check bearing noise and shaft seal condition in preventive maintenance; bearing wear and seal leakage from coolant contamination are common failure modes.

Adaptive QA & Testing Protocol

Each 8LSA45.EA030D100-3 servo motor is bench tested on B&R ACOPOS servo amplifier test rig. We verify motor rotation across full speed range, check EnDat 2.2 encoder position feedback and signal integrity. Winding insulation resistance and three-phase winding balance are measured. Winding temperature sensor circuit and bearing noise are inspected. Connector pins, motor flange and shaft are visually inspected for corrosion, scratches or seal damage. Full test reports or bench test video clips are available upon request.

Buyer’s FAQ

Q: What is B&R 8LSA45.EA030D100-3 used for? A: It is a B&R 8LS 45mm flange synchronous servo motor with 1.31Nm,3000rpm, EnDat 2.2 single-turn encoder and OCT single cable, used for high-precision machine axis motion control with ACOPOS drives.

Q: What warranty applies for refurbished and NSFP 8LSA45.EA030D100-3? A: Refurbished and NSFP units carry a 12-month hardware warranty. Coverage excludes ESD damage, cable short circuits, mechanical shaft/bearing overload, improper B&R parameter setup and seal damage from liquid ingress.

Q: What lead time should I expect? A: Stocked units ship 3–7 business days. If inventory is depleted, lead time increases while we source surplus B&R 8LSA45.EA030D100-3 servo motors.

Q: Does this motor come with holding brake? A: This variant (D100) is without holding brake. Brake-equipped variants use different code suffix.
