Abstract: A centrifugal blood pump for circulating blood is provided, wherein an impeller makes no contact at all with a housing and a rotating shaft and moves in a rotating manner with the impeller in a stably levitating state. Also provided is a blood pump in which the impeller rotates at high speed even when the blood pump is reduced in scale. The blood pump contains a magnet of enhanced magnetic force at the inside of a housing and at an outer peripheral surface of an impeller and providing a fixed-interval spacing on the periphery of a bearing section makes it possible to ensure a state where no contact at all is made between the housing, a shaft, and the impeller, and makes it possible to cause the impeller to rotate stably over a long period of time.

Abstract: A magnetic thrust bearing for use in a device for relatively free rotational movement of a first part relative to a second part includes axial and laterally spaced magnets. Each magnet has a magnetic field of force with opposing poles and a transition section which converges to a transition line. Axial magnets are spaced on an axis of the first part of the device and lateral magnets are arranged on the second part of the device. The lateral magnets operating in units, having paired lateral magnets positioned on opposite sides of the axis with each of the paired magnets having an equal length and equal gap or space from the axis. Axial magnets have an alternating polar orientation such that the nearest magnetic poles of adjacent axial magnets are repelling, and the distance between transition lines of the axial magnets is substantially equal to the length of the lateral magnets. Accordingly, the magnetic field of force of each lateral magnetic unit is perpendicular and attracting to the repelling fields of force between adjacent axial magnets for lateral displacement of the first part relative to the second part by a fixed gap, so that, with this arrangement, the permanent-magnet bearing enables non-contact, relative motion between the two parts of the device using both attractive and repelling forces generated by magnets.

Abstract: Apparatus and methods for providing a pre-determined axial thrust force profile for use in a rotating machine that includes a magnetically permeable rotor with first and second surfaces and a generally perpendicular shaft is disclosed. One or more bearings support the shaft and a coil induces flux in the rotor. First and second pole pieces disposed adjacent to the first and second surfaces define first and second gaps. A series magnetic circuit including the pole pieces, the gaps and the rotor carries flux generated by current flowing in the coil. Pole pieces and gaps provide substantially similar reluctance in both gaps. Magnetic saturation characteristics of a series magnetic circuit may provide a pre-determined axial force profile as a function of coil current. A first magnetic saturation characteristic may provide a maximum axial force at a first current magnitude. A second magnetic saturation characteristic may provide a lower axial force at a current greater than the first current. The saturation characteristic may be formed by configuring the geometry and dimensions of the poles. The axial force profile may be formed to reduce the net axial thrust load on the bearings.
