Centrifuge construction having central stator

摘要: A centrifuge construction is disclosed in which a centrally located stator directly drives peripheral ring shaped rotor. In the preferred embodiment, drive includes stationary, central and usually cylindrical having stationary electrical windings for generating rotating driving magnetic field. The rotor supported by at least one bearing relative to large aperture defined inside of enables fit over rotate about stator. At portions adjoining stator, constructed from materials are entrained containing samples undergoing centrifugation driven entrainment with field generated usual case, this requires use composite resist radial centrifugal forces during hoop stress resistance wound material fibers.
