<p>An artificial heart pump includes a cylindrical stator (11) provided between the inner surface of a casing (1) and a rotor (2) so as to establish a blood flow channel (46) between the outer surface of the stator and the inner surface of the casing, and a rotating magnet (6) and a stationary magnet (7) differing in length in their N-S pole directions provided on the rotor and the stator with their N-S pole directions aligned parallel with the axis of rotation. The boundary (6') between the N and S poles of the rotating magnet (6) is positioned closer to a pivot (8) than the boundary (7') between the N and S poles of the stationary magnet (7). <IMAGE></p> |
