Product Description:
The 8MSE8L.E1-P12C is manufactured by B&R Automation for the 8MS Three Phase Synchronous Motors series. It is a servo-class rotary actuator that converts power from a pulse-width-modulated inverter into controlled mechanical motion for loads requiring precise speed and position regulation. The motor can supply continuous torque to pick-and-place arms, indexing tables, conveyor axes, and other automated machinery. Its single-cable connection carries the required power and feedback signals between the motor and control system, reducing the number of separate connections routed along the machine. High-resolution position data allow the motion controller to coordinate the motor with other axes during synchronized operating profiles.
The feedback output has a bandwidth of at least 100 kHz at -3 dB, allowing the encoder signals to remain responsive during rapid acceleration and high-speed movement. Position error is limited to ±60 arcseconds, supporting accurate shaft-angle measurement throughout the motor’s operating range. The incremental track provides 512 lines per mechanical revolution, and compatible drive electronics can interpolate this signal for finer position control. Communication uses the EnDat protocol to transmit position, diagnostic, and parameter data through a differential interface. The installed multi-turn encoder retains the absolute shaft position across power interruptions, allowing the controller to recover the recorded position without performing a complete homing cycle. This capability can shorten startup procedures on machinery that must preserve axis position while power is unavailable.
The motor has a stack-depth code of L, indicating the axial length used for this configuration. Its flange corresponds to frame size 8, providing the mounting dimensions associated with the same motor platform. The encoder can distinguish absolute positions across 4096 revolutions, giving the controller a 12-bit range for tracking complete shaft turns. This multi-revolution range supports applications in which the connected mechanism travels through many rotations before returning to its initial position. The unit has a large relative rated torque, making it suitable for loads that require sustained torque during constant-tension winding, coordinated camming, or repeated indexing. Its magnetic and thermal capacity supports demanding motion cycles while the feedback system continues to report the shaft position to the controller.
