8JSA63.R0023D100-0 by B & R Automation

The 8JSA63.R0023D100-0 is produced by B&R Automation and belongs to the 8JS Synchronous Motors series. As a compact servo motor, it supports closed-loop torque and velocity control for machinery axes, conveyors, and pick-and-place stations where synchronized motion is required. Because it is supplied without an integrated holding brake and without an oil seal, the motor is better suited to clean, dry operating environments or to systems that provide external load holding. This arrangement is useful in applications where the axis cycles frequently but does not need a built-in brake to remain fixed at standstill.

The motor reaches a nominal speed of 2250 rpm, which gives the drive a stable continuous operating velocity for regular motion tasks. Heat is removed through a self-cooling design that uses the housing surface as a radiator, eliminating the need for forced airflow or liquid circuits. Rotor position is detected by a resolver, and its feedback tolerance is held within 10 angular minutes, which helps maintain dependable feedback under vibration and electrical noise. Mechanical integration is simplified by flange mounting, which provides a fixed reference plane for alignment to gearboxes or direct-drive loads. Power and feedback conductors exit through an angled swivel connector, allowing cable routing in tight spaces while reducing strain at the connection point.

The frame is categorized as size 6, which suits medium-torque applications that need a compact installation footprint. It uses a length 3 active stack, increasing copper volume for higher continuous current within the same frame family. Torque is transferred through a keyed shaft end, which provides positive mechanical engagement with couplings or pulleys instead of relying only on clamping force. This output style is commonly used where repeatable torque transmission is needed during acceleration, deceleration, and frequent reversing cycles.
