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.

Abstract: A swinging bucket rotor (R1) constructed of composite material having a central rotor body (B1) is disclosed. This central rotor body (B1) includes strap retaining surfaces (30, 31, 32). Wound endless composite fiber straps (S1, S2, S3, S4) having central portions (14) are attached to the respective top and bottom of the central rotor body (B1) and loop portions (16) remote from the central rotor body (B1) for mounting the swinging buckets (K1). These wound endless straps (S1, S2, S3, S4) attach centrally to the central rotor body (B1) at the strap retaining surfaces (30, 31, 32) and define bucket retaining loops (16) symmetrically spaced from the spin axis (20) of the rotor (R1). Each bucket retaining loop (16) holds spaced apart bushings (22) for receiving a trunion shaft (24). Paired trunions (24) on either side of a central sample tube receiving ring (26) are provided. The trunions (24) fit to the composite loop portions (16) of the endless composite material straps (S1, S2, S3, S4).

Abstract: A method and apparatus for compression molding of fiber fixed angle rotors. Female mold (F) defines cylindrical bore (14) for molding the bottom of the rotor. Bore (14) defining frustum shaped central cavity (C) complementary to and concentric with the spin axis of the rotor. Male mold (M) contains frustum shaped inner cavity (C) with the apex of frustrum (18) disposed to the inner portion of bore (14) and the base of frustum (18) exposed to the cylindrical opening of mold (F). Inner cavity (C) defines the exterior shape of the rotor and defines between the exterior profile and the inner cavity (C) a rotor body wall. At the apex of inner cavity (C) there is a lock system for maintaining cores (K) in alignment with sample tubes of the rotor. Loading with resin pre-impregnated fiber occurs in inner cavity (C) and at the bottom of mold (F).

Abstract: A centrifuge construction is disclosed in which a centrally located stator (S) directly drives a peripheral ring shaped centrifuge rotor (R). In the preferred embodiment, a centrifuge drive is disclosed which includes a stationary, central and usually cylindrical stator (S) having stationary electrical windings (40A-40D) for generating a rotating and driving magnetic field. The ring shaped centrifuge rotor (R) is supported by at least one bearing (G1, G2) relative to the stator (S) and includes a large central aperture (A) defined by the inside of the ring which enables the rotor (R) to fit over and rotate about the stator (S). At portions of the rotor (R) adjoining the stator (S), the rotor (R) is constructed from materials which are entrained by the rotating magnetic field. The centrifuge rotor (R) containing samples (28) undergoing centrifugation is directly driven from the stator (S) by entrainment of the rotor (R) with the rotating and driving magnetic field generated from the electrical windings (40A-40D) of the stator (S).
