Kollmorgen TBM2G Frameless Servo Motors

Kollmorgen TBM2G is a frameless brushless servo-motor family for embedding into robotic joints and other custom mechanisms. Seven frame diameters and three stack lengths provide a selection of electromagnetic packages; the finished axis still needs its own bearings, structure, feedback and drive.
Key Specifications
Specification | Details |
Construction | Frameless rotor/stator motor components for embedded integration |
Frame sizes | 050, 060, 068, 076, 085, 094 and 115; nominal outer diameters 50–115 mm |
Stack selection | Three stack lengths per frame; multiple winding options |
Design voltage context | Designed for operation at 48 VDC and below |
Thermal sensing | PT1000 and PTC options in the documented family |
Commutation sensing | Optional integrated Hall sensors |
Mechanical integration | Machine designer supplies final bearing, housing and rotor/stator retention arrangement |
Thermal interpretation | Current literature discusses performance below 85°C and continuous winding capability up to 155°C; these are not allowable human-contact temperatures |
Engineering Assessment
TBM2G is relevant when a joint designer needs to integrate the motor around the mechanism rather than adapt a housed servo motor. Its selection range supports packaging tradeoffs, but torque, temperature and accuracy must be qualified in the final assembly. The motor alone does not establish collaborative-robot safety or an environmental protection rating.
Applications
Embedded robotic joints, medical mechanisms and other compact custom axes where the designer can engineer the mechanical support, thermal path and control integration.
Industries: Robotics and automation; medical equipment; aerospace and defense; embedded motion equipment
