Product Description:

The B&R Automation 8MSA5X.E3-D30C1 is a three-phase synchronous motor in the 8MS Three Phase Synchronous Motors series. Designed as a compact drive element for industrial handling, packaging, and processing equipment, the unit converts electrical power into controlled rotational motion for closed-loop servo axes. It is suited for automated machines that need repeatable positioning, steady torque delivery, and a compact installation footprint. Its construction supports direct mounting to machine frames and provides the torque density needed for rapid positioning tasks in multi-axis automation cells.

Mechanically, the motor is assigned size 5 and length code X, giving a moderate stack height without exceeding envelope limits. Power and feedback conductors exit on the top side of the housing, which simplifies routing inside vertical cabinets. Heat is removed through a self-cooling design that relies on natural convection rather than forced air. The motor has a nominal shaft speed of 3000 rpm, and its relative rated torque is extra large, making it suitable for heavy-load acceleration. A keyed shaft end provides positive mechanical coupling, and the assembly is supplied without a holding brake, so external restraints must secure the load during power-off states. No oil seal is fitted at the output, which reduces friction in dry environments.

Position feedback is provided by an EnDat inductive encoder. The encoder is a multi-turn device that can distinguish up to 4096 complete revolutions and provides one-revolution feedback with 32 lines. Its interpolation tolerance is ±400, supporting precise contouring at high speed. The feedback signal supports frequencies of ≥ 6 kHz (-3 dB), allowing fast control-loop sampling. The inductive measurement principle resists contamination and vibration, which helps maintain stable commutation during dynamic operation.
