B&R 8LSA45.EA030D100‑3
Product Overview
The B&R 8LSA45.EA030D100‑3 is a self‑cooling three‑phase synchronous servo motor from the B&R 8LS motor family, engineered for high‑dynamic positioning applications paired with B&R ACOPOS, ACOPOSmulti and ACOPOS P3 drive platformsB& R Indus…. It is fitted with EA‑variant inductive single‑turn EnDat 2.2 feedback encoder, rotatable angled circular speedtec connectors, smooth shaft without holding brake, and delivers strong peak overload capability for cyclic production machinery. This motor features low cogging torque, high energy efficiency and robust IP64 housing for machine‑mount deployment. It is widely implemented in packaging machinery, plastic injection equipment, metal‑forming automation and material‑handling lines, and serves as critical spare hardware for existing B&R motion‑control system replacement and retrofit projectsB& R Indus….

Typical Application Scope
‑ High‑speed packaging automation machinery, pick‑and‑place positioning axes ‑ Plastic processing equipment, injection molding and extrusion auxiliary motion axes ‑ Metal‑cutting, forming and press‑automation production lines ‑ Material‑handling and conveyor high‑dynamic positioning systems ‑ Spare‑part replacement and retrofit for existing B&R 8LS‑3 servo motor installations
Maintenance & Inventory Manager Practical Notes
- Common field failure modes: Shaft‑side oil seal wear leading to grease leakage; connector pin damage from cable mechanical tension; encoder circuit damage caused by drive‑side voltage transients; bearing aging under continuous cyclic high‑speed operation.
- Compatibility note: Confirm encoder variant, shaft configuration and brake status before spare‑part swap. This EA version is single‑turn inductive encoder; multi‑turn encoder variants cannot be substituted directly without project modification. Match drive firmware version to motor electronic name‑plate data.
- Pre‑shipment test checklist: Visual inspection of shaft surface, connector shell and housing integrity; winding insulation resistance test; encoder signal communication validation with matching B&R drive; rotate shaft manually to check for abnormal friction or noise; multi‑hour power‑on burn‑in test.
- Spare‑parts stocking strategy: 8LS‑3 series motors are widely deployed on production‑critical machinery. OEM lead‑times for specific configured variants can be extended. Plants running non‑stop manufacturing lines should maintain on‑site spare units to minimize production downtime.
Critical Installation Pitfalls
‑ Strictly implement ESD anti‑static handling procedures; static discharge can damage sensitive inductive encoder electronics without visible damage. ‑ Avoid applying mechanical load by pulling motor cables directly from circular connectors; relieve cable strain with cable clamps. ‑ Respect motor shaft radial and axial load limits; excessive mechanical load accelerates bearing premature failure. ‑ Verify encoder parameter auto‑read function on B&R drive after motor replacement; incorrect encoder data will trigger position‑tracking faults. ‑ Keep adequate surrounding airflow for self‑cooled motor; enclosed tight mounting compartments will cause over‑temperature alarms.
