Latest Patents

Frank Drautz's latest patents focus on spindle motors equipped with fluid dynamic bearing systems. One of his notable inventions describes a spindle motor featuring a fluid dynamic bearing system with several unique components. The motor consists of a base, a stationary shaft connected to the base, and a hub that is rotatably supported relative to the shaft. This design includes two bearing plates arranged around the shaft, separated by a gap that is partially filled with a bearing fluid. The inclusion of stopper plates connected to the shaft, which abut each bearing plate, creates independent fluid dynamic bearing systems. This innovative arrangement is powered by an electromagnetic drive system.

Another significant patent by Drautz details a spindle motor that includes a rotor component designed as an integrated hub/bearing bush configuration. This rotor encloses a straight, stationary shaft, which is connected to axially aligned bearing components that effectively seal the fluid dynamic bearing system formed between the rotor and the shaft. The inventive use of capillary and pumping seals at the open ends of the bearing gap exemplifies Drautz's ingenuity in enhancing motor performance.
