Product Description:
The 8JSA63.R0023D105-0 belongs to the 8JS Synchronous Motors series from B & R Automation. This three-phase synchronous motor is intended for precise speed and torque regulation on packaging lines, pick-and-place axes, and other motion modules that rely on closed-loop servo control. When integrated with a matching B & R drive, the motor acts as a compact rotary actuator that converts electrical power into repeatable mechanical rotation while remaining synchronized with the command profile. Its synchronous design supports controlled acceleration, steady operation, and accurate positioning during repetitive machine cycles.
The motor has a rated speed of 2250 rpm, which supports continuous operation under nominal voltage and suitable thermal conditions. Heat is removed through self-cooling, meaning that airflow over the housing keeps the winding temperature within allowable limits without a separate fan. Rotor position is detected by a resolver, and the feedback system provides an accuracy of 10 angular minutes. This position feedback helps the connected drive maintain stable current loops and smooth velocity regulation as the mechanical load changes. Power and feedback leads exit through an angled swivel connector, allowing cables to be routed along the machine frame without creating an excessive bend. The motor is supplied without a holding brake, so static load retention must be provided by drive-applied torque or an external mechanical clamp when power is removed.
The motor supports flange mounting, which centers the housing and provides a rigid face for connection to gearboxes or direct-drive loads. Torque is transmitted through a keyed shaft, preventing movement between the shaft and properly fitted hub components. The electromagnetic stack uses length code 3, while the motor uses frame size 6. This combination provides a compact form for mid-range motion axes while supporting the motor’s intended torque capacity. Because the shaft does not include an oil seal, the interface should be used in clean, dry surroundings. An external seal may be added when the installation could expose the shaft opening to oil, coolant, moisture, or other contaminants.
