8JSA52.E6045D200-0
The 8JSA52.E6045D200-0 is a synchronous servo motor produced by B&R Automation for the 8JS Synchronous Motors series. As a drive element, it converts electrical energy from a matched inverter into controlled mechanical rotation for indexing tables, packaging axes, and other precision automation tasks. Size code 5 and motor length 2 set the motor’s envelope and active stack length, which helps match the unit to available mounting space and torque demand. This layout suits applications that need repeatable acceleration, controlled stopping, and stable positioning under changing load conditions.
This model reaches a nominal speed of 4500 rpm, allowing fast cycle times when paired with suitably rated gear stages or direct-drive loads. Its housing supports flange mounting, so the stator face bolts directly to machine frames and helps preserve alignment under thrust. Heat is removed by self-cooling, so no external fan or liquid circuit is required. A smooth shaft end minimizes runout and is ready for press-fit couplings, while the integrated holding brake supplies 14.5 Nm of static torque to keep vertical or inertial loads in position after power is removed. Because there is no oil seal, the shaft interface should remain in a clean, dry area during installation and operation.
Feedback is supplied by an optical encoder that delivers 2048 lines per revolution and a total angular accuracy of ±20 arcsec. The interface uses the Optical EnDat 2.1 protocol, which provides bidirectional digital data exchange between the motor and the drive. Single-turn construction reports one absolute revolution, and the 13/0-bit resolution supports precise speed and position control without an additional sensor. Power and feedback conductors exit through an angled swivel connector, which helps route cables in confined enclosures and reduces strain at the connection point. The encoder feedback also lets the drive track rotor position continuously during acceleration, deceleration, and low-speed holding.
