Kollmorgen is redefining motion design with its range of frameless brushless servo motors that eliminate traditional housings, shafts, bearings, and connectors to deliver the most compact, torque-dense motion possible.
By embedding only the rotor and stator directly into a machine’s mechanical structure, engineers can achieve higher performance, reduced weight, and greater design freedom.
Frameless servo motors are ideal for applications such as rotary actuators and robotic joints where precision and torque density are critical. Using the host machine’s own bearings and housing, these motors integrate seamlessly and can even be protected from harsh environments, enabling lighter, more durable, and maintenance-friendly systems.
Kollmorgen’s latest TBM2G Series represents the next generation of frameless servo technology. Optimized for voltages up to 48 VDC, the TBM2G offers seven frame sizes and multiple stack lengths and windings for unmatched design flexibility. Its innovative torquer (pancake) architecture provides exceptional torque output in a compact, thermally efficient package that performs at just 85 °C winding temperature, ideal for confined spaces and sensitive components.
With proven performance, scalability, and rapid prototyping capabilities, Kollmorgen’s frameless motors empower engineers to create more compact, efficient, and reliable motion systems tailored to advanced unmanned and robotic applications.
