DC-Micromotors with graphite commutation

Highly stable and low-wear graphite commutation, extremely powerful neodymium magnets and a particularly high copper content in the winding of the FAULHABER rotor give the CR series its enormous power. The impressive power range of 19 to 224 mNm is ideal for high-performance applications with fast start/stop operation or periodic overload conditions.

Thanks to the extremely high power density as well as the outstanding dynamics with minimal rotor inertia, the CR family is the most powerful product family of the entire FAULHABER DC range. The standard drive can be combined with highresolution optical or magnetic encoders for applications with precise speed control or positioning tasks. A broad and optimally matched selection of precision gearheads is available to extend the range of requirements that this series is able to fulfil.

While electric mobility is becoming ever more popular, there is still room for developing functional standard technologies in some areas. One such example is the way cars are charged: nobody wants to see streets littered with charging stations. And while inductive charging is largely hidden from…
