Product Description:

The TBM-6013-B is a frameless brushless motor segment produced by Kollmorgen within the TBM Frameless Motors series. As a torque-producing core that is built directly into machine structures, the unit supplies rotary motion without an external housing, enabling compact designs in cobots, gimbals, and precision stages. The frameless format lets the rotor and stator be integrated directly into the host mechanism, which reduces envelope size and removes the need for a separate motor housing. Its role is to deliver controlled torque and speed where available space and weight are limited in industrial automation.

At thermal equilibrium, the motor can hold 0.39 N·m of continuous torque, and achieving this output requires a phase current of 6.78 Arms. For short acceleration bursts, the electromagnetic circuit tolerates a peak torque of 1.23 N·m before saturation. Mechanical output includes a rated speed of 3540 RPM and a rated power of 103 W for continuous operation. The stator has 0.355 Ω of resistance at 25 °C and 0.15 mH of inductance, which influence current response and switching behavior in the drive. Twelve poles support high torque density and smooth commutation. Static friction is 0.021 N·m, and viscous damping is 0.00204 N·m/kRPM, which helps the controller account for low-speed drag.

Electrical behavior includes a back-EMF constant of 3.66 Vrms/kRPM, so generated voltage rises in proportion to motor speed. The torque constant is 0.061 N·m/Arms, allowing current commands to be translated directly into torque output. Rotor inertia is 0.0000141 kg·m², and the complete rotor-stator set weighs only 0.221 kg, which helps limit load on lightweight mechanisms and supports quick acceleration. Nominal operation is intended on a 24 VDC bus, aligning with common low-voltage motion platforms.
