摘要:
A pump includes an impeller (310), a stator (380), and a plurality of permanent magnets (320) forming bearing poles coupled to a selected one of the stator or the impeller. The pump further includes a plurality of shorted coils (370) coupled to the other of the stator or the impeller. The magnets may be arranged as a Halbach array. The plurality of bearing poles and shorted coils co-operate to form an electrodynamic bearing during rotation of the impeller. The electrodynamic bearing supports the impeller either axially or radially during operation of the pump. Currents induced into each coil by a single bearing pole or by a plurality of bearing poles substantially simultaneously produce an electrodynamically generated magnetic field that repels the inducing bearing pole(s) when the impeller is rotating.
