8JSA32.R0030D000-0 by B & R Automation

The 8JSA32.R0030D000-0 is a synchronous motor produced by B&R Automation for the 8JS Synchronous Motors series. In an automation cell, it converts commanded current into regulated mechanical rotation, allowing positioning stages, conveyor zones, or pick-and-place heads to follow precise motion profiles. The unit's permanent-magnet design supports repeatable torque delivery during start, stop, and speed-holding tasks. Its compact construction lets it fit behind machine guarding without increasing enclosure depth, which helps in machines where installation space is limited.

Continuous operation is set around a nominal speed of 3000 rpm, a value used for electrical frequency selection and inverter sizing in stable velocity loops. Heat generated at that load is removed through a self-cooling scheme that relies on surface convection, eliminating external blowers. Mechanical attachment is handled by flange mounting, which centers the stator face against the machine frame and helps maintain alignment during axial thrust. For feedback, the motor uses an internal sensor arrangement that resolves shaft position to within 10 angular minutes, supporting synchronized multi-axis motion and repeatable speed regulation. Because cooling is passive, nearby components are not affected by fan airflow or additional fan hardware.

The feedback element is a Resolver, chosen for analog operation where electrical noise or vibration could disturb digital encoder signals. Power and signal cabling exit through an angled swivel connector, a layout that eases routing in tight cabinets and helps prevent sharp cable bends near the housing. The rotor terminates in a smooth shaft, permitting couplings or timing pulleys that seat by friction rather than keys. The housing uses the motor length 2 designation and the motor size 3 frame code, giving a compact format for medium-duty axes. The motor is supplied without a holding brake and without an oil seal, so external retention and sealing must be provided when the application requires them.
