8JSA63.R0023D105-0 by B & R Automation

The 8JSA63.R0023D105-0 is a synchronous motor produced by B&R Automation within the 8JS Synchronous Motors series. In automation cells, it supplies controllable torque and speed so actuators, feeders, or conveyors can be driven directly from a servo amplifier. The motor's mechanical frame follows IEC dimensions, letting machine builders bolt it through the flange face without extra adapter plates. Integrated position feedback links with the drive controller to maintain commanded motion profiles under variable load. This layout suits compact production equipment where stable servo response and straightforward mechanical integration are both important.

During continuous operation, the rotor reaches 2250 rpm, a nominal speed suited to mid-range feed axes that do not require high-speed spindle behavior and still benefit from smooth motion at process speeds. Heat generated by copper losses is removed through self-cooling, eliminating the need for external fans or liquid jackets and simplifying cabinet ventilation requirements. Rotor position is measured with a resolver, a durable electromagnetic sensor whose analog sine-cosine output resists interference from dust and oil. The electrical angle it reports carries an accuracy of 10 angular minutes, which is adequate for indexing tables and moderate-precision pick-and-place robots. Mechanical fixation uses flange mounting, so thrust forces pass directly into the machine frame rather than through a foot or cradle.

Power and feedback leads exit through an angled swivel connector that can be rotated for strain-relieved routing inside tight enclosures. This arrangement also helps when the motor must fit beside guards, cable trays, or gearbox housings. Drive selection is guided by the frame code; the stator is size 6, while the stack depth uses length code 3, placing the motor within the corresponding 8JS housing envelope. The output is provided through a keyed shaft, enabling slip-free coupling with standard hubs. The motor has no holding brake and no oil seal, which suits applications with low inertial loads and external sealing provided elsewhere.
