8JSA54.EB050D200-0
The 8JSA54.EB050D200-0 is a synchronous servo motor produced by B&R Automation, and it belongs to the 8JS Synchronous Motors series. The unit is intended for flange-mounted integration into machine axes where fast indexing and velocity regulation are required. It converts drive current from a matched inverter into mechanical rotation for automation cells, packaging stations, and pick-and-place modules. Its synchronous design supports controlled acceleration, repeatable positioning, and stable velocity behavior in automated motion systems.
This model reaches a nominal shaft speed of 5000 rpm, allowing rapid cycle completion in high-throughput equipment. Heat is removed through self-cooling, so no external fan or liquid circuit is needed and the cabinet layout stays simpler. Position feedback is supplied by an inductive EnDat 2.1 encoder. This interface streams absolute position data directly to the drive for tight servo loops. The encoder’s code width is 19/12 bits for single-turn and multi-turn words, giving fine digital granularity over one revolution as well as across multiple turns. Accuracy of the transmitted position is held within ±180 arcsec, which limits interpolation error when coordinating multiple axes. That combination lets the drive maintain precise commutation and position tracking during fast directional changes.
The feedback module stores up to 4096 mechanical turns, letting the controller recover absolute rotor angle after power loss without homing routines. Static holding requirements are handled by an integral brake that supplies 14.5 Nm of torque, so vertical loads remain fixed when the drive is disabled. Power and feedback conductors exit through an angled swivel connector, easing cable routing in tight enclosures and permitting rotation to relieve strain. The motor uses motor size 5, and length code 4 balances torque density with overall depth. This layout helps the motor fit compact machine frames while maintaining secure load holding at standstill.
