Kollmorgen Introduces Robot-Ready Frameless Servo Motors

Kollmorgen, a provider of motion control systems, has announced the TBM2G series of frameless servo motors to simplify the design of collaborative, surgical, aerospace, defence and other robots.

Kollmorgen is a provider of motors, drives, linear actuators, gearheads, AGV control solutions and automation platforms. The company operates as part of Altra Industrial Motion Corp., a designer and producer of a wide range of motion control and power transmission solutions.

The TBM2G series joins Kollmorgen’s existing TBM and KBM series of frameless motors. The TBM2G series offers torque in a compact electromagnetics package that enables robots with lower joint weight, higher load-carrying capacity, improved energy efficiency, lower thermal rise, and faster, smoother movements.

“We’re excited to introduce new servo motors that significantly increase overall performance while reducing size in a wide range of frameless applications”, said Jeff Czarnecki, Vice President, Global Marketing at Kollmorgen. “And we’re particularly excited at the possibilities the TBM2G series opens up for robotics. TBM2G motors are a perfect fit for a new generation of high-performance cobots. They are truly robot ready”.

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 power, torque and efficiency consistently across a wide speed range, says Kollmorgen. TBM2G motors also remove the sizing limitation that engineers often face when using off-the-shelf strain wave gearing, also known in the robotics market as harmonic gearing. The new TBM2G series motors are sized to fit with readily available strain wave systems, eliminating the need for customizations.

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.

These motors are designed to perform at high speeds without exceeding the 80°C limit typically needed to safeguard humans working in proximity to cobots and to prevent degradation of grease and electronic components. They’re also available with thermal sensor options to meet the requirements of drives and control systems used in the cobot market.
