    Abstract: The present invention relates to a magnetic gear comprising a first magnetic rotor with a first shaft; and a second magnetic rotor with a second shaft; a support structure, with a first end shield and a second end shield connected by a stat or support element. A first bearing attached to the first end shield supports the first shaft and a second bearing supports the second shaft. The first and second magnetic rotors are displaced in axial direction from each other in an axial gap; and the first shaft and shaft are approximately aligned in opposite axial directions; and a plurality of magnetic flux conductors encircles the first and second magnetic rotors, thereby conducting magnetic flux from the first magnetic rotor to the second magnetic rotor. The magnetic gear comprises a dividing wall arranged in the axial gap between the first magnetic rotor and the magnetic second rotor, to separate a first chamber from a second chamber.

    Abstract: A centrifugal blood pump without a mechanical bearing comprises a pump casing (1), an impeller (9) arranged in the pump casing rotatably about the central axis and freely movable axially and radially within a limited clearance. The impeller has permanent magnets or permanently magnetized magnetic regions (N/S) which cooperate with an electromagnetic drive to set the impeller rotating. A circular wall (12) or circularly arranged wall sections are provided within the pump casing, their inner surfaces defining a radial clearance together with the outer circumference of the impeller to form a hydrodynamic radial bearing for the impeller.

    Abstract: An impeller 31 is provided with a rotating shaft rotatably supported at the upper and lower ends thereof by an upper bearing 9 and a lower bearing 10, a plurality of vanes 32 connected to the rotating shaft on the inner circumferential edge side thereof, an annular coupling portion 8 connecting outer circumferential edges of the vanes, and driven magnet portions 12 provided in a lower portion of the annular coupling portion. The rotation of a rotor is transmitted to the impeller through magnetic coupling between the driven magnets 12 and drive magnets 16 provided to the rotor 13. The upper edge of each of the vanes has a bend point, and an angle ± formed by a peripheral upper vane edge 33a and an angle ² formed by a central upper vane edge relative to the downward direction of the rotating shaft are both acute angles and have a relationship of ±

    Abstract: A centrifugal fluid pump assembly (200) comprises a centrifugal fluid pump (205) and a control device (206). The centrifugal fluid pump (205) comprises a centrifugal fluid pump section including a housing and an impeller having a first magnetic material and a second magnetic material disposed thereof and accommodated for rotation in the housing and without contacting the housing, an impeller rotational torque generating section including a rotor having a magnet for attracting the first magnetic material and a motor for rotating the rotor, and an impeller position control section having an electromagnet for attracting the second magnetic material. The control device (206) includes a monitoring function of monitoring electric current flowing through the electromagnet; a monitoring function of monitoring motor-driving current; a monitoring function of monitoring the number of rotations of the motor; and a function of determining whether or not the impeller has a power swing by utilizing a current value monitored by the electric current monitoring function, a value of the motor-driving current monitored by the motor-driving current monitoring function, and the number of rotations of the motor monitored by the monitoring function of monitoring the number of rotations thereof.
