8JSA22.E9080D000-0 by B & R Automation

B & R Automation builds the 8JSA22.E9080D000-0 as part of its 8JS Synchronous Motors series. The device is an AC servomotor intended for closed-loop industrial automation, where it delivers repeatable torque and speed to indexing tables, gantry axes, and feed drives. An inductive multi-turn encoder is integrated so the controller always knows absolute rotor position after power loss, allowing quick start-ups. The absence of a holding brake targets applications that maintain position through drive torque rather than mechanical locking.

The electrical section is rated for a nominal shaft speed of 8000 RPM, giving the axis short cycle times in packaging or semiconductor tooling. Heat is removed by the motor's own frame through Self-cooling, so no external fan or liquid circuit is required. Position feedback uses an Inductive EnDat 2.1 interface, permitting bidirectional communication with the drive for diagnostics and electronic nameplate data. Within that system, the sensor supplies 18/12 bits of position data for single and multi-turn counts, and its mechanical precision is specified at ±280 arcsec, enabling fine contouring at high speed.

The encoder tracks up to 4096 revolutions, so absolute position remains valid over long travel distances or during power interruptions. Electrical and feedback cabling exit via an Angled (swivel connector), which simplifies routing in cramped cabinets and allows the connector body to rotate for strain relief. Mechanical attachment follows Flange mounting dimensions aligned with the motor's size-2 frame, while the rotor presents a Smooth shaft that mates with clamp couplings or shrink-fit hubs without key slots. Combined with self-contained cooling and a compact length code 2 housing, these features reduce installation time on multi-axis machines.
