Product Description:

The 8MSA5M.E0-GU00-1 is a three-phase synchronous servo motor built by B&R Automation within the 8MS Three Phase Synchronous Motors series. It provides closed-loop drive power for positioning axes, conveyor segments, and gantry systems where accurate torque delivery and speed regulation are required in automated production lines. Its servo design supports repeatable motion in equipment that depends on stable speed control and responsive axis behavior.

The feedback system relies on the EnDat protocol, enabling bidirectional digital communication between the motor encoder and the drive. Position information is generated by an optical disk with 512 lines, and internal interpolation supports fine commutation and velocity loops. Absolute accuracy is maintained because the encoder precision is rated at ±60", which limits cumulative position error during repetitive moves. Dynamic control is helped by a signal bandwidth of ≥ 100 kHz (-3 dB), so high-speed sampling does not attenuate incremental edges. The sensing element is a single-turn device, giving one absolute position per motor revolution and allowing homing sequences to be skipped in most machine cycles.

Thermal management is handled through a self-cooling design that dissipates stator losses without external fans or liquid loops, which simplifies surrounding airflow requirements. The motor frame belongs to size code 5, which matches the mechanical envelope used for this platform. Its axial build follows length code M, balancing continuous torque output against overall inertia for mid-range mechanical loads. Drive selection charts list the relative rated torque as Medium, indicating suitability for applications that need moderate continuous torque while still allowing current margin for short acceleration bursts. This operating profile fits machines that alternate between frequent starts, short moves, and steady running during normal production.
