2338S012S - Faulhaber dc-micromotor. 3VDC-- 12VDC/50mA. Mitat 23X38mm. Made in Germany

The main difference between FAULHABER DC micro motors and conventional DC motors is in the rotor. The rotor does not have an iron core but consists of a self-supporting skew-wound copper winding. This featherweight rotor has an extremely low moment of inertia, and it rotates without cogging. The result is the outstanding dynamics of FAULHABER motors. For low power micro motors, commutation systems using precious metals are the optimum solution because of their low contact resistance.
