Product Description:
The 8JSB32.D5070U600-0 synchronous motor is manufactured by B&R Automation for the 8JS Synchronous Motors series. This unit supplies precise rotary power to automated handling, packaging, and small-parts assembly equipment where tight speed regulation and repeatable positioning are required. By integrating mechanical, electrical, and feedback functions into a standardized housing, the motor simplifies axis construction in modular industrial machinery. Its compact design also supports installation in equipment with restricted mounting space.
Its nominal speed rating is 7000 rpm, allowing the shaft to complete multiple revolutions per second while remaining within the synchronous operating range of the drive. Power conductors and digital encoder lines are routed through a single-cable solution, which reduces the connector count and required cabinet space. The housing has a straight cable exit, allowing direct routing along linear guides or machine frames. Thermal energy is removed by a self-cooling aluminum stator body, eliminating the need for external blowers while preserving the enclosure seal. For mechanical integration, the motor uses flange mounting. The machined face provides a concentric pilot and bolt circle that align the rotor with gearheads, belt pulleys, or directly coupled loads. Motor length code 2 provides additional stack depth for higher continuous torque.
The motor has a frame size of 3, which establishes the outer diameter and bolt spacing while providing more torque capacity than smaller frame sizes. A front-end oil seal blocks lubricant migration where the shaft passes through the bearing area. This seal also helps prevent contaminants from entering around the shaft opening. The output uses a smooth shaft, which mates with clamp couplings or shrink disks without introducing backlash from a keyway. Because the motor is supplied without a holding brake, a static load must be secured by the drive’s torque-holding capability or an external mechanical clamp when power is removed. The shaft and flange arrangement allows accurate alignment with compact transmission components, while the cable configuration reduces the number of separate connections required at the motor.
