When the Motor Becomes Part of the Joint – Frameless Torque Motors in Medical Robotics
Learn how frameless torque motors are becoming an integral part of robot joints. Maximise torque density and system stiffness in medical robotics for superior performance and compact designs.
Anyone developing robot joints today can no longer ignore frameless torque motors. The requirements for size and weight, torque density, system stiffness, and control bandwidth are often no longer achievable with classic servomotors.
The motor as an integral part of the joint
In modern robot joints, the motor is no longer simply attached but becomes an integral part of the overall system. These so-called frameless motors open up completely new design possibilities for engineers while simultaneously increasing their own value creation.
Design freedom vs. engineering challenge
Using frameless motors requires developers to solve issues such as bearings and sensors themselves. In return, however, you get a system that is perfectly optimised for the application – whether in surgical robotics, precise positioning systems, or particularly compact handpieces.
Advantages for medical technology
- Compactness: Minimal size with maximum performance.
- Lightweight construction: Significant weight reduction by eliminating the motor housing.
- Performance: Higher system stiffness and improved control bandwidth.
Rely on the next generation of drive technology for your medical applications.
