Product Description:
The 8JSA22.R0080D200-0 synchronous motor is manufactured by B&R Automation and belongs to the 8JS Synchronous Motors series. It serves as a compact drive element for machines that require repeatable high-speed rotation and accurate position feedback. By combining resolver sensing with an integrated holding brake, the unit supports automation axes that require controlled stopping and quick restart cycles. Its compact design also makes it suitable for positioning, indexing, and material-handling equipment where installation space is limited.
This model reaches a nominal speed of 8000 rpm, allowing rapid positioning while staying within the thermal limits of its self-cooling housing. A holding brake rated at 1.42 Nm keeps the shaft fixed when power is removed, helping prevent load drift on vertical or indexing stations. Resolver feedback provides an angular precision of 10 arcminutes, so the controller can maintain fine velocity and position loops without an external encoder. The power and feedback conductors exit through an angled swivel connector, reducing cable strain in confined machine layouts. This connector orientation also allows the conductors to be routed away from nearby mechanical components and moving assemblies.
The motor uses a flange mounting arrangement that supports direct attachment to compatible gearboxes, couplings, or machine plates. Its smooth shaft transfers torque through friction or clamp-style hubs without requiring a keyway. The active housing has motor length 2, while the stator frame has motor size 2; these dimensions provide the physical envelope and load capacity associated with this model. No oil seal is fitted around the shaft, so the shaft area should be protected from direct fluid exposure when the motor is installed in washdown zones. Suitable guarding or placement can help prevent coolant, lubricant, and cleaning fluid from reaching the unsealed shaft opening. The housing and connection arrangement allow the motor to fit compact machine axes without requiring a separate feedback device or an auxiliary cooling system.
