Product Description:
The 8JSA63.R0023D700-0 is a synchronous servo motor produced by B&R Automation as part of the 8JS Synchronous Motors series. It is used in industrial automation systems where precise rotational motion is required to move gantries, conveyor sections, or process tooling. By pairing the rotor’s permanent-magnet field with pulse-width-modulated stator currents, the motor delivers controllable torque and speed for closed-loop positioning tasks. This operating principle allows the connected drive to regulate acceleration, maintain the commanded velocity, and correct position errors as load conditions change.
It sustains a rated shaft speed of 2250 rpm, allowing midrange linear feed rates when coupled to ball screws or gear reducers. Heat generated in the stator is removed through self-cooling. The housing’s fin geometry allows natural convection to maintain acceptable operating temperatures without auxiliary blowers. Rotor position is measured by a resolver, and the feedback path maintains a resolution of 10 angular minutes, providing the drive controller with sufficient granularity for tight velocity and position loops. Mechanical integration is handled through flange mounting, which locates the motor on a precision pilot and transmits reaction forces directly into the machine frame. The size code 6 and length index 3 provide a moderate stack length that balances continuous torque with installation depth.
Cabling is simplified by an angled swivel connector that allows the power and signal plugs to rotate toward the preferred exit direction during installation. The unit is supplied without a holding brake, so static load retention must be achieved through external clamps or drive torque when mains power is removed. A shaft-side oil seal prevents grease or cutting fluid from entering the front bearing cavity and protects the feedback chamber from contamination. Drive torque reaches the load through a keyed shaft, providing positive mechanical engagement during bidirectional acceleration. The rotating connector can also reduce sharp cable bends when the motor is installed near machine panels or structural members. External load-holding provisions are necessary for vertical or gravity-loaded axes that must remain stationary after power is disconnected.
