Abstract
An artificial heart pump comprises a cylindrical stator provided between the inner surface of a casing and a rotor so as to establish a blood flow channel between the outer surface of the stator and the inner surface of the casing, and a rotating magnet and a stationary magnet 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 between the N and S poles of the rotating magnet being positioned closer to a pivot than the boundary between the N and S poles of the stationary magnet.
