Internal Product Review
The 8MSA3S.E1-30 is a B & R Automation three-phase synchronous motor with self-cooling and a 3000 rpm rated speed. An EnDat multi-turn encoder supports consistent position feedback for demanding servo duty. Clean signal quality from the 512-line encoder resolution is a strong advantage for precise motion control.

Product Description:
The 8MSA3S.E1-30 three-phase synchronous motor is built by B&R Automation and belongs to the 8MS Three Phase Synchronous Motors series. Designed for servo axes and general motion tasks, the unit converts electrical energy into controlled rotational motion for conveyors, packaging machinery, and pick-and-place stations within automated lines. The product integrates a multi-turn EnDat encoder for feedback and relies on self-cooling through its frame, reducing the need for external cooling hardware. A smooth shaft simplifies coupling to gearboxes or pulleys during installation.
During continuous operation, the motor reaches a rated speed of 3000 rpm, allowing direct connection to drive trains that expect standard high-speed spindle behavior. Position feedback is provided at 512 lines per revolution by the built-in encoder, and interpolation supports tight velocity and position loops. Communication takes place through the EnDat serial interface, so the drive controller can read multi-turn data and diagnostic information over a single shielded cable. Heat is removed by the housing’s self-cooling design, eliminating the need for an external blower and keeping enclosure layouts compact. During installation, the shaft may be pressed with up to 200 N of axial force, which helps during pulley or coupling assembly.
The encoder bandwidth reaches ≥ 100 kHz (-3 dB), and its precision remains within ±60", supporting fine interpolation across the motor’s multi-turn range of 4096 recognized revolutions. Mechanical connection is streamlined by a smooth shaft, and wiring exits on the A side of the stator to keep cable routing predictable inside tight cabinets. The motor uses length code S and size code 3, provides a relatively small rated torque, and is supplied without a holding brake or oil seal to reduce mass for fast-moving axes.
