Product Description:

The 8JSA54.R0050D100-0 is a synchronous servo motor manufactured by B&R Automation for the 8JS Synchronous Motors series. Intended for industrial automation systems, it transforms regulated current from a servo drive into repeatable mechanical rotation, enabling indexing tables, feeders, and labeling heads to reach commanded positions with minimal lag. By delivering controlled torque across a broad speed range, the motor serves as a core motion element wherever precision, compact size, and electronic coordination with PLC software are required. This operating profile suits equipment that depends on stable response during frequent starts, stops, and positioning moves.

Its rated rotational speed reaches 5000 rpm, allowing fast cycle times when index distances must be traversed. Heat is removed by a self-cooling aluminum frame that relies on surface convection rather than fans. Rotor position is measured by a sensor whose electrical accuracy is 10 angular minutes, and the use of a resolver for this feedback provides resistance to electrical noise and high temperatures. Frame geometry follows series conventions: the housing is classified as size 5 and built in construction length code 4, which set the stator active length and mounting footprint. The design omits a holding brake, so static load retention must be provided by the drive or by an external mechanism. Because no oil seal is fitted, the shaft area should remain free from lubricant.

Mechanical integration is supported by flange mounting holes machined into the front endplate, permitting direct attachment to gearboxes or machine frames. Output torque is delivered through a keyed shaft, enabling straightforward coupling with pulleys or rigid hubs while maintaining rotational alignment. Electrical terminations are routed through an angled swivel connector, which allows the plug to be positioned to match cable routing and reduce strain without disturbing the motor body. This connection arrangement also helps reduce the space needed behind the motor, which is useful in compact cabinets or closely spaced machine assemblies.
