Kollmorgen has announced the new TBM2G series of frameless servo motors, introducing features to simplify the design of collaborative, surgical, aerospace and defence and other robots while delivering optimal performance in a lighter, more compact package, the company writes in a press release. The new motors complement Kollmorgen’s existing TBM and KBM series of frameless motors. According to Kollmorgen, the TBM2G series offershigh-performance torque in an extremely compact electromagnetics package, allowing robots with:
- lower joint weight
- higher load-carrying capacity
- improved energy efficiency
- lower thermal rise
- faster, smoother movements
Frameless torque motors typically deliver their best performance at low speeds but suffer at higher speeds. TBM2G motors remove this limitation through advanced windings and materials that deliver industry-leading power, torque and efficiency consistently across a wide speed range, Kollmorgen emphasises. TBM2G motors are also said to remove the sizing limitation that engineers often face when using off-the-shelf strain wave gearing. The TBM2G series is available in seven frame sizes with three stack lengths each. A total of 21 standard motors that can be integrated directly into robotic joints and similar embedded equipment. Typical applications are collaborative robots in the 3–15 kg range, powered at 48 VDC and below.
