Product Description:

The 8JSA73.R0024D100-0 is a synchronous motor manufactured by B & R Automation for the 8JS Synchronous Motors series. Designed as a compact rotary drive element, it converts electrical power from the drive into controlled torque and speed for indexing tables, pick-and-place heads, or conveyor axes in automated machinery. As part of an integrated motion system, the motor supplies repeatable positioning accuracy while maintaining the electrical characteristics and feedback interface standardized across the 8JS platform.

Under rated conditions, the rotor reaches 2400 rpm, a nominal speed that balances dynamic response with thermal limits. Heat is removed through self-cooling, so no external blower or liquid circuit is required; the housing surface alone dissipates operating losses. For closed-loop control, the motor uses a resolver with electrical angle feedback accurate to within 10 angular minutes, allowing the controller to command fine incremental moves. The unit is supplied without a holding brake, so static load retention must be provided by the drive or external mechanics. The motor has a length code of 3, and the absence of an oil seal means the shaft should be protected from direct fluid exposure in oily environments.

The electrical and feedback leads exit through an angled swivel connector, which simplifies cable routing in tight cabinets and permits the plug to rotate for strain relief. The motor supports flange mounting, allowing the frame to seat directly against gearboxes or machine plates while preserving alignment through the machined pilot. The frame is classified as size 7, providing a reference for the exterior diameter, bolt circle, and permissible torque. Motion is transferred through a keyed shaft that provides positive engagement with pulleys or couplings and prevents slippage during high-acceleration starts.
