8JSA32.R0055D100-0
The 8JSA32.R0055D100-0 synchronous motor is produced by B&R Automation for the 8JS Synchronous Motors series. It serves as the rotary actuator that converts commanded current into torque and speed so automated stations can index, feed, or position tooling with repeatable accuracy. In an industrial cell, the motor works with matching power modules and motion controllers to support consistent axis movement in packaging, handling, and general automation equipment. Its compact servo-style design also allows direct integration where precise rotary motion is required without adding unnecessary mechanical complexity.
Its nominal operating speed is 5500 RPM, allowing high-throughput axes to run directly at elevated shaft speed. Position feedback is supplied by a resolver, a rugged electromagnetic device that remains dependable in applications exposed to vibration and electrical noise. The feedback system reaches an intrinsic accuracy of 10 angular minutes, helping the drive maintain stable position correction during repeated motion cycles. Thermal management relies on a self-cooling housing that dissipates heat through convection rather than forced airflow, which simplifies installation where fan maintenance or extra air routing is undesirable. Installation is accomplished through flange mounting, which keeps the motor aligned with the driven load and supports rigid attachment to the machine structure.
Electrical connections exit through an angled swivel connector, allowing cable routing to turn back toward the machine frame in confined spaces. The motor uses a keyed shaft end so torque can be transferred positively to a coupling or pulley without relying only on clamping force. This unit is built in size 3 with length 2, giving a recognizable frame format for space planning and inertia matching within the 8JS platform. The motor is supplied without a holding brake and without an oil seal, so any static load retention or additional sealing must be provided by the surrounding machine design. These omissions make the motor better suited to applications that do not require built-in shaft sealing or brake-assisted holding at standstill.
