Product Description:
B & R Automation manufactures the 8JSA33.R0045D100-0, a synchronous motor in the 8JS Synchronous Motors series. Designed for closed-loop motion axes, the unit converts drive current into precise rotary movement for positioning tooling, conveyors, or feeders in automated equipment. The stator and rotor support high acceleration, while the mounting interface simplifies integration with gearheads or direct-drive assemblies. The motor provides stable speed regulation and repeatable torque for coordinated multi-axis applications in industrial automation.
The nominal speed reaches 4500 rpm, allowing fast indexing without exceeding the intended speed range of the magnetic circuit. Heat is removed through a self-cooling design that relies on rotor-generated airflow, so an external blower is not required. The motor uses flange mounting, and the power and feedback leads exit through an angled swivel connector that helps keep cable loops short in confined installation spaces. Output torque is transmitted through a keyed shaft, which provides positive engagement with a compatible coupling. The housing is supplied without an oil seal, so the coupling area must remain free of process liquids that could reach the shaft opening.
The feedback system uses a resolver to report rotor position to the drive and offers a resolution of 10 angular minutes for commutation and closed-loop speed control. Because the motor is supplied without a holding brake, static loads must be secured by external mechanical equipment when power is removed. The motor has a size 3 frame and an active stack designated as length 3, providing an appropriate balance of inertia and peak torque for medium-power axes. Its feedback arrangement allows the connected drive to monitor shaft movement and correct position or speed deviations during operation. Cable routing should preserve adequate bend clearance around the swivel connector while preventing strain at the motor connection point.
