Kollmorgen Introduces a New Generation of Robot-ready Frameless Servo Motors

Radford, US – Kollmorgen, a global leader in motion control systems, recently announced the new TBM2G series of frameless servo motors, which include features that simplify the design of collaborative, surgical, aerospace and defense, and other robots while providing optimal performance in a lighter, more compact package. These new motors will be used in conjunction with company’s existing TBM and KBM series of frameless motors.

The TBM2G series, the result of years of research, testing, and customer feedback, provides high-performance torque in an extremely compact electromagnetics package. These next-generation motors enable robots with lower joint weight, greater load carrying capacity, higher energy efficiency, lower thermal rise, and faster, smoother movements.

Frameless torque motors typically perform best at low speeds but suffer at higher speeds. TBM2G motors overcome this limitation with advanced windings and materials that consistently deliver industry-leading power, torque, and efficiency across a wide speed range.

TBM2G motors also eliminate the sizing constraint that engineers frequently face when using off-the-shelf strain wave gearing, also known as harmonic gearing in the robotics market. The new TBM2G series motors are sized to perfectly fit with readily available strain wave systems, eliminating the need for extensive customizations, which can increase engineering time and cost while potentially causing supply and quality issues when robots enter full production.

The TBM2G series is available in seven frame sizes with three stack lengths each—a total of 21 standard motors that can be directly integrated into robotic joints and other embedded equipment. Collaborative robots weighing 3–15 kg and powered by 48 VDC or less are typical applications. These motors are designed to operate at high speeds while not exceeding the 80°C limit typically required to protect humans working in close proximity to cobots and to prevent grease and electronic component degradation. They’re also available with thermal sensor options to meet the needs of drives and control systems used in the cobot market.

The company is well-equipped to deliver TBM2G motors in any volume, anywhere in the world, with quick production times, reliable quality, and local co-engineering support.

Jeff Czarnecki, Vice President, Global Marketing, Kollmorgen, commented, “We’re excited to introduce new servo motors that significantly increase overall performance while reducing size in a wide range of frameless applications. 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.”
