Winding Technology
A Heart of Copper

A guest contribution by Dr. Fritz Faulhaber | Translated by AI 6 min Reading Time

The winding of an electric motor is essential for its efficiency and power density. At Faulhaber, it is continuously optimized, allowing for increasing miniaturization. The focus of development is on the copper filling factor, winding symmetry, and space requirements.

The Faulhaber portfolio today encompasses around 25 motor families—from brushed and brushless DC motors to stepper and linear motors, as well as integrated drive systems. Various lengths, diameters, and numerous combination possibilities ensure that these drives can reliably perform their tasks in a wide range of environments. The fields of application range from A for automated agricultural robotics to Z for reliable medical technology. As diverse as the applications may be, they are all united by one key element at their core: an advanced winding that significantly determines the performance of the motors.
