Product Description:

The RBE-03010-C00 is a frameless brushless rotary motor kit manufactured by Kollmorgen as part of the RBE Rotary Motors series. Supplied as separate rotor and stator rings, the unit is embedded in OEM mechanical structures to deliver direct electromagnetic torque for compact indexing tables, rotary actuators, and other precision axes used in industrial automation. Its frameless construction eliminates shaft-coupling components, reducing backlash and allowing the motion system to fit into tight radial envelopes common in semiconductor tooling and robotic joints. This layout also lets the surrounding structure act as the mounting platform, which helps conserve space in compact rotary assemblies.

At its continuous operating limit, the motor develops 2.99 N-m while drawing 2.96 Arms from the drive. These values align with the torque constant of 1.06 N-m/Arms, so controller current setpoints translate linearly into shaft torque. A back-EMF constant of 63.9 Vrms/kRPM describes the voltage required to overcome generated flux as speed increases. The rated speed is 2900 RPM, and at that point the 4.21-ohm phase resistance and 8.2 mH inductance shape thermal dissipation and filter high-frequency switching. These electrical values limit di/dt, reduce current ripple, and help the drive maintain stable vector control across the speed range. Static friction is only 0.127 N-m, which helps keep low-speed positioning smooth.

For rapid positioning moves, the motor withstands a peak stall torque of 20.6 N-m and up to 21 Arms of phase current, providing a short-term reserve that is more than six times the continuous rating. Output mechanical power reaches 701 W at rated speed, delivered through a 12-pole rotor that supports high torque density at low frequency. The assembled stack weighs 1 kg, and the 0.000275 kg-m² rotor inertia supports short settle times during repeated start-stop motion. Viscous damping of 0.0000686 N-m/kRPM minimizes heat and lets the servo hold commanded dwell speeds without hunting.
