Product Description:
The 8MSA6M.E1-D400-1 three-phase synchronous motor is manufactured by B&R Automation within the 8MS Three Phase Synchronous Motors series. Designed for servo axes in packaging machines, material-handling lines, and general automation, it converts three-phase supply power into regulated torque and speed under drive control. The unit integrates directly with B&R amplifiers to deliver repeatable motion profiles in closed-loop applications where positional accuracy and cycle time are critical.
At a nominal shaft speed of 3000 rpm, the motor operates at its rated operating point under matched drive control. Position feedback is supplied by a multiturn EnDat encoder that provides 512 lines per revolution, allowing the drive to interpolate fine incremental steps. The scanning head has a -3 dB cutoff frequency of ≥ 100 kHz, supporting rapid traverses without losing the position count. Angular accuracy is maintained within ±60 arcseconds, which supports consistent positioning in indexing tables and pick-and-place arms. Communication occurs over the EnDat serial link, reducing wiring while delivering absolute position and diagnostic data to the control cabinet.
A permanent-magnet holding brake rated at 32 Nm secures the shaft whenever power is removed, preventing gravity or process forces from back-driving the axis. The multiturn sensor records up to 4096 complete revolutions, so homing routines are unnecessary after shutdowns. Thermal management relies on self-cooling, and the absence of a fan reduces maintenance requirements. A smooth shaft end simplifies connection to precision clamping hubs, while the electrical terminals are oriented on top of the housing for straightforward cable routing. Frame size 6 with length code M provides an inertia level suited to the motor’s medium relative torque classification. The assembly is delivered without an oil seal, so external contamination barriers must be provided when the motor is installed in washdown areas or locations exposed to fluids.
