Frameless Servo Motors

Kollmorgen TBM2G series simplifies design of collaborative, surgical, and aerospace robots.
Kollmorgen has introduced its TBM2G series of frameless servo motors that offer high-performance torque in a compact electromagnetics package. The company says the line eliminates the limitations of traditional frameless motors – low speeds and sizing issues – due to its advanced windings and materials and the fact that they are sized to fit off-the-shelf strain wave systems. The series is available in seven frame sizes with three stack lengths each—a total of 21 standard motors. Typical applications are collaborative robots in the 3 to 15 kg range, powered at 48VDC and below. These motors are designed to perform at high speeds without exceeding the 80°C cobot limit. They’re also available with thermal sensor options to meet the requirements of drives and control systems used in the cobot market.
