Built‑in function:Integrated gear‑type synchronous servo motor outputs large low‑speed torque without external reducer. Resolver feedback provides reliable position signal for servo drive. KTY84 temperature sensor monitors winding real‑time temperature to prevent motor burnout. Low‑backlash gear unit guarantees positioning accuracy. IP65 protection adapts industrial dust‑proof and splash‑proof requirements. Compact integrated structure saves cabinet installation space.

Product Brief
8MSA3M.R0‑42 belongs to B&R 8MS servo motor family,with integrated 42‑ratio precision gearbox. It is specially designed for working conditions requiring low‑speed and high‑torque output.
Resolver feedback owns strong anti‑interference capability,adapts to equipment with large vibration. Integrated reducer avoids additional mechanical installation work. Cooperates with ACOPOSmulti series inverter modules to realize high‑precision position,speed and torque control.
This is legacy spare part,widely used for maintenance and hardware replacement of original B&R automation equipment. Before purchase,please confirm drive matching,output torque‑speed requirement and mechanical shaft‑end dimension. ESD protection shall be followed during installation. Power cable and feedback cable sold separately.
