8JSA42-R0015D700-0 by B & R Automation

B & R Automation produces the 8JSA42-R0015D700-0, a synchronous motor belonging to the 8JS series. As a rotating actuator, it converts drive current into mechanical output that can be synchronized with other motion axes in an automated cell. The compact frame and flange interface are intended for direct integration into conveyors, indexing tables, or pump stages where precise speed holding and low-maintenance operation are required. It is suited for machines that need steady rotary motion and straightforward installation. Because the design omits an internal brake and relies on a sealed shaft end, it is suited for applications that already include external locking devices.

The motor reaches a nominal speed of 1500 RPM, enabling direct coupling to mechanisms that operate at common industrial rates without additional gearing. Size code 4 establishes a moderate stator diameter that balances inertia and torque density, while length code 2 extends the magnetic stack to increase continuous output within the same mounting circle. Thermal energy is expelled through self-cooling, so airflow around the housing is sufficient and no external fan or liquid circuit is required. The motor uses flange mounting, which locates the pilot on a machined shoulder for repeatable alignment with gearboxes and eliminates the need for foot brackets during installation.

Cabling exits through an angled swivel connector, letting the plugs rotate 300 degrees for strain relief when the motor is installed in confined panels. Rotor position feedback is delivered by a resolver, and its electrical precision of 10 angular minutes supports stable speed loops where fine interpolation is unnecessary. Torque is transferred by a keyed shaft, which locks the hub mechanically and tolerates repetitive start-stop cycles. A fitted oil seal retains lubricant inside the adjoining machine element and helps shield the bearing seats from contaminants. External clamping or drive torque must secure the axis during power-off states.
