摘要： PCT No. PCT/CH96/00117 Sec. 371 Date Oct. 1, 1997 Sec. 102(e) Date Oct. 1, 1997 PCT Filed Apr. 2, 1996 PCT Pub. No. WO96/31934 PCT Pub. Date Oct. 10, 1996The rotary machine comprises a driven rotor and an electric motor having a stator and a driving rotor. The stator is also executed as an electromagnetic bearing for the driving rotor, and the driving rotor of the electric motor together with the driven rotor of the rotary machine forms a rotor unit, i.e. the two rotors form an integral rotor. The rotary machine can for example be a rotary pump, a centrifugal pump, a centrifuge or a stirring apparatus. The rotor can be constructed so as to be easily removable from the stator.

摘要： PROBLEM TO BE SOLVED: To provide an artificial heart pump having a constitution for rotating an impeller while being supported in a noncontact state, restraining a mechanical loss, and improving pump efficiency.
SOLUTION: This artificial heart pump has the impeller 3 rotatably supported to a fixed shaft body 2 in a housing 1, and a driving mechanism for rotating this impeller, and forcibly sends blood backward by taking in from the front by rotation of the impeller 3. The shaft body 2 is connected between a front side fixed body 5 fixed to a straightening plate 4 joined to the housing 1 in front of the impeller 3, and a rear side fixed body 7 fixed to a diffuser 6 joined to the housing 1 in the rear of the impeller 3. The impeller 3 is composed of a sleeve 8 having front-rear end surfaces opposed in microscopic clearance to a rear end surface of the front side fixed body 5 and a front end surface of the rear side fixed body 7, together with an inner peripheral surface opposed in microscopic clearance to an outer peripheral surface of the shaft body 2, and an impeller 9 joined to an outer peripheral surface of the sleeve 8. The driving mechanism is composed of a polar anisotropic permanent magnet 10 contained in the sleeve 8, and a rotating magnetic field generator 11 contained in the housing 1.

摘要： PROBLEM TO BE SOLVED: To provide a blood pump apparatus having a form of substantially preventing blood reverse flow through the blood pump apparatus and allowing a limited amount of the blood reverse flow for preventing the formation of blood clot when the blood pump apparatus breaks down. SOLUTION: The blood pump 301 having a single clearance is provided with a rotor 322 and a stator 323, and the rotor 322 imperfectly closes a blood channel by the axial movement in the stator. The rotor 322 magnetically supported inside the stator 323 pumps the blood in the direction of an arrow 304 from a pump entrance 302 to a pump exit 303. The rotor 322 is magnetically supported to stator magnetic force bearing parts 308 and 310 and rotor magnetic force bearing parts 309 and 311. The magnetic bearing parts radially center the rotor in a housing but has a passive centering stiffness to the radial centering so as not to axially stabilize inside the stator 323.
