Beschreibung
Zusammenfassung:	A ventricular assist device (100) includes a housing assembly (10) with a pressurized inner chamber (18), an impeller (20), an electric motor (30) and a distance sensor (40). The electric motor (30) includes a controller (33), a stator (31) and a rotor (32). The stator (31) and the controller (33) are located in the housing assembly (10), outside of the pressurized inner chamber (18) and are electrically coupled. The impeller (20) and the rotor (32) are located in the pressurized inner chamber (18) and fixedly coupled. The distance sensor (40) is located in the housing assembly (10), outside of the pressurized inner chamber (18) and electrically coupled to the controller (33). The distance sensor (40) senses a distance value of the rotor (32) to a cavity wall of the pressurized inner chamber (18), and further transmits the distance value to the controller (33). The controller (33) controls a magnetic force between the stator (31) and the rotor (32) according to the distance value, so as to control a suspension and rotation of the rotor (32).
