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

Abstract: In a centrifuge having a central stator with a peripheral rotor, an improved suspension for the rotor is disclosed. The central stator is provided with a bore coaxial to the axis of rotation of the rotor. The rotor of the centrifuge motor has a quill shaft support member extending into and rotating within the coaxial bore of the stator. A quill shaft attaches at the bottom of the quill shaft support member and extends upward above the rotor of the centrifuge motor to support a fastening hub for the centrifuge rotor. The rotor of the centrifuge is detached from the rotor of the centrifuge motor so as to define a spatial interval between the supported spinning rotor and the rotor of the motor driving the centrifuge. The centrifuge rotor attaches at the hub and depends downward from the hub with the spatial interval being defined between the rotor of the motor and the rotor of the centrifuge. It is noted that the center of gravity of the attached centrifuge rotor is well below the hub so that support of the rotor is inherently stable. In the preferred embodiment, heat transfer shielding material is placed over the rotor of the motor. Operation is quite and smooth with the inevitable rotor imbalances being absorbed by quill shaft flexure.

Abstract: A swinging bucket rotor constructed of composite material has a central rotor body including strap retaining surfaces. Wound endless composite fiber straps are provided having central portions which are attached to the respective top and bottom of the central rotor body and loop portions remote from the central rotor body for mounting the swinging buckets. These wound endless straps attach centrally to the central rotor body at the strap retaining surfaces and define bucket retaining loops symmetrically spaced from the spin axis of the rotor at the central rotor body. In the preferred embodiment, each bucket retaining loop holds spaced apart bushings for receiving a trunion shaft. Paired trunions on either side of a central sample tube receiving ring are provided. The trunions fit to the composite loop portions of the endless composite material straps. Typically, four sample receiving buckets are placed within and held by the central sample tube receiving rings. Such loading of the buckets occur by the bucket being lowered into the sample tube receiving rings until they are pendulously supported through the rings by the trunions. There results a swinging bucket rotor having top loading sample tube apertures constructed at its sample retaining loops from composite material disposed in tension with the benefit of reduced construction cost and operational complication.

Abstract: An improved rotor suspension for a centrifuge (C) having a central stator (S) with a rotor (RC) is disclosed. The stator (S) is provided with a bore (114) coaxial to the axis of rotation of the rotor (RC). The rotor (RM) of the centrifuge motor has a quill shaft support member (118) extending into and rotating within the bore (114) of the stator (S). A quill shaft (Q) attaches at the bottom (120) of the quill shaft support member (118) and extends upward above the rotor (RM) of the centrifuge motor to support a fastening hub (H) for the centrifuge rotor (RC). The rotor (RC) of the centrifuge is detached from the rotor (RM) of the centrifuge motor so as to define a spatial interval between the supported spinning rotor (RC) and the rotor (RM) of the motor driving the centrifuge. The center of gravity of the centrifuge rotor (RC) is well below the hub (H) so that support of the rotor (RC) is stable. Rotor imbalances are absorbed by quill shaft flexure.
