Product Description:
The 8JSB33.D4020U600-0 is a synchronous servo motor produced by B & R Automation for the 8JS Synchronous Motors series. As an electromechanical actuator, it converts drive current from a servo inverter into precise rotary motion needed for indexing tables, pick-and-place heads, and other industrial automation axes. The motor’s rotor-stator construction is optimized for quick torque response, while its stator windings connect directly to the manufacturer’s hybrid cabling architecture, simplifying integration with B&R drive systems.
At its rated speed of 2000 rpm, the motor delivers consistent mechanical output suitable for medium-inertia loads that require accurate velocity regulation. Electrical power and encoder feedback share a single-cable hybrid connection, reducing cabinet wiring and minimizing installation time. All connectors exit the housing in a straight orientation, so harnesses can run parallel to the axis without tight bends. Heat produced during duty cycles is removed through self-cooling, meaning airflow over the aluminum frame is sufficient and no external blower or liquid circuit is necessary. The length code 3 stator stack provides the magnetic volume needed to support these operating characteristics.
The mechanical envelope uses flange mounting, allowing the front face to bolt directly to gearboxes or machine plates while maintaining repeatable alignment. A smooth shaft transmits torque without a keyway, making it suitable for backlash-free clamping hubs. Contaminant ingress is limited by an integral oil seal, permitting use in areas that require light washdown. The motor has a size 3 frame, giving it a compact diameter that matches B&R planetary gearheads. It is supplied without a holding brake, so the drive or an external brake module must retain static loads when power is removed. The housing and connector arrangement support parallel cable routing where limited clearance prevents sharp cable bends near the motor body.
