FAULHABER brushed motor differ from conventional iron core DC motors in that the rotor consists of a self-supporting, skew wound copper coil. Among the inherent properties of this pioneering design are an extremely low rotor inertia and zero cogging or preferred rotor position. These factors help to define the uniquely high, power to volume ratio of the motors as well as their extremely dynamic performance characteristics.
Originally invented by Dr. Fritz Faulhaber Sr. and patented in 1958, the System FAULHABER coreless (or ironless) progressive, self-supporting, skew-wound rotor winding is at the heart of every System FAULHABER DC Motor. This revolutionary technology changed the industry and created new possibilities for customer application of brushed motor where the highest power, best dynamic performance, in the smallest possible size and weight are required.
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.
