One atmospheric implantable axial-gap whole blood pump of the magnetic drive and a control method

The present invention discloses a whole is formed between the axial-flow implantable blood pump and a control method, the stator and the permanent magnet magnetically driven one atmospheric nip air gap; a stator including a stator core, stator windings and the insulating layer; a stator core three symmetrically cogging circumferential direction of the stator; a stator winding of three sets of coils, stacked in full pitch on the stator teeth; opened upper surface of each of the stator teeth and the relative position of the same shape as the chute, the insulating layer is made of a resin into; TI4 fixing sleeve is made of a material. The present invention, by optimizing the design of the stator structure, so that the overall light weight, small size, high torque, low temperature, the control circuit making the alternating current of three sets of coils, realized on the stator teeth N, S, and the state of the permanent magnet N, S poles coupled; system startup does not start winding, a simple structure, the motor is started and the electromagnetic implantable pump based on a mechanical - hydrodynamic design characteristics, with smooth acceleration, rapid, applicability characteristics.
