8KSJ86.S1015b200-0 by B & R Automation

The 8KSJ86.S1015b200-0 is a synchronous drive motor supplied by B & R Automation as part of the 8KS Synchronous Motors series. Designed for servo axes in automated machinery, the unit converts three-phase electrical input into controlled mechanical rotation while maintaining strict temperature limits through its integrated cooling system. It provides the torque source for positioning tables, packaging lines, and similar equipment where precise speed regulation and continuous duty are required.

Mechanical integration is simplified by the flange mount with a B-side base, allowing either face mounting or base mounting on the machine frame. The stator uses a closed water-cooled circuit, and the heat exchanger is installed on the right side so hoses can be routed away from the encoder compartment. Within the 8KS platform, this model uses the 8KSJ construction variant. It combines motor size 8 with motor length 6 to deliver its rated output, and it is identified as Motor Version 0. Speed regulation extends to a nominal value of 1500 rpm, while the serial interface follows the EnDat 2.2 protocol to exchange real-time position and status data with the drive controller. No special option is selected for this configuration.

An EnDat multi-turn functional safety encoder based on an optical operating principle supplies absolute position feedback. Within each revolution, it resolves 33,554,432 (25-bit) discrete positions and distinguishes up to 4096 complete turns, supporting accurate homing after power loss. Angular accuracy is specified at ±20´´, enabling tight loop gains in high-precision motion tasks. As a three-phase synchronous motor, the unit delivers constant torque across its rated speed range, making it suitable for coordinated multi-axis systems where deterministic feedback and thermal management minimize drift.
