Abstract
A magnetic gear having first and second carrier each having a plurality of magnetic poles arranged in a circle and separated by a distance, with the north and south poles arranged in alternation. Flux-carrying connecting pieces are provided on a third carrier to magnetically couple the first and second carriers. A centrifuge for centrifuging biological fluids, especially blood, having such a magnetic gear includes a first carrier in a stationary mount on a frame, while the third carrier is a rotating frame in a rotating mount on the frame. The second carrier is a separation unit mounted on the rotating frame. The centrifuge using the magnetic gear allows maintenance-free operation at a high rpm and with low noise, requiring a relatively low driving power.
