Product Description:

The RBE-06202-F08 is a rotary motor core produced by Kollmorgen for the RBE Rotary Motors series. The assembly consists only of a rotor and stator set intended for direct embedding inside customer-supplied housings. By positioning the electromagnetic section directly at the load, the design can shorten drivetrain length and reduce coupling compliance. In automated equipment, this motor section supplies controlled torque for robotic joints, precision indexing tables, and compact spindle drives where envelope size and dynamic response are critical. Its format lowers inertia and enables tight coupling to the load, which improves motion response on demanding axes.

This model is classified as a frameless brushless unit, meaning commutation is electronic and the active components are supplied without a separate enclosure. During continuous operation, it can hold a stall torque of 44.3 N·m, which is the maximum steady load the shaft can resist without moving while current remains within thermal limits. For transient events such as acceleration or impact loads, the magnetic circuit can deliver up to 234.8 N·m of peak torque, giving a more than five-to-one margin over its continuous rating. Torque is generated through a three-phase winding; the stator uses 3 electrical phases with a permanent-magnet rotor that carries 12 poles, a combination that helps produce a smooth electromagnetic waveform and reduce cogging. Rotor position for commutation is detected by integrated Hall sensors, allowing simple trapezoidal or sinusoidal drive control without an external encoder.

The mechanical package uses a rotor and stator construction and is supplied without endbells, so cooling flow and mounting features must be provided by the host machine. This open format keeps the assembly mass to 11.5 kg, which helps reduce reflected inertia when the motor is mounted around a joint or spindle. The exposed architecture leaves room for axial cable routing, external liquid jackets, or direct integration of the laminations into a structural hub. Because the active components are provided without a housing, the surrounding machine structure determines how heat is removed and how the assembly is supported in operation.
