Product Description:

The 8MSE6X.E3-X32C-1 is a three-phase synchronous motor engineered by B & R Automation as part of the 8MS Three Phase Synchronous Motors series. The unit converts electrical input into controlled rotary motion for positioning, conveying, and coordinated axis tasks within automated machinery. Its electromagnetic design allows closed-loop velocity and torque control when paired with matching inverters, making the device suitable for servo applications that demand high cycle accuracy and repeatability. The integrated feedback encoder provides absolute position data, so machine controllers can issue precise motion profiles without additional external sensors.

With a frame size of 6 and an extended stack identified by length code X, the motor provides a larger magnetic volume for higher continuous torque density within the same flange pattern. Rotor position is captured by an integrated absolute encoder that delivers 32 lines per mechanical revolution before internal interpolation. The electronic interface supports a feedback bandwidth of at least 6 kHz at -3 dB, allowing the drive to process rapid position updates without excessive encoder-induced phase lag. The feedback head uses EnDat inductive sensing, which minimizes sensitivity to dust and vibration compared with optical alternatives. This noncontact sensing method also supports reliable position measurement during repetitive acceleration and deceleration cycles.

The encoder’s absolute accuracy is specified at ±400, allowing the controller to maintain positional errors within the stated angular window during closed-loop operation. Because the encoder uses a multi-turn system, it tracks shaft rotations across power cycles and counts up to 4,096 turns through a nonvolatile counter. This capability eliminates the need for external homing routines in long-stroke gantries and other machines where the axis position must remain available after a shutdown. The motor has an extra-large relative rated torque, indicating that its continuous torque capability is higher than that of other 8MS motors sharing the same flange size. The available torque supports heavy inertial loads, while the absolute feedback system helps the drive manage rapid start-and-stop sequences accurately.
