Claim 12:
13. A total artificial heart system comprising:
at least one artificial ventricle configured to be coupled to at least one of a pulmonary artery, a vessel of a heart, and a chamber of a heart;
at least one drive system coupled to the at least one artificial ventricle and configured to cause a volume of the at least one artificial ventricle to contract and expand, the at least one drive system comprising at least one electric motor; and
at least one power supply electrically coupled to the at least one electric motor;
wherein the at least one artificial ventricle and the at least one drive system are configured to be implanted in a chest cavity of a patient,
wherein the at least one electric motor includes:
a stator assembly comprising (i) a circular base, (ii) at least one housing longitudinally extending from the circular base, and (iii) a plurality of winding groups disposed radially inward of and/or radially outward of the at least one housing; and
at least one rotor disposed radially outward of the at least one housing, and

wherein at least one of the following conditions is satisfied:
(16A) wherein the at least one housing includes a hexagonal housing disposed radially inward of the plurality of winding groups and further comprises a cylindrical housing disposed radially outward of the plurality of winding groups;
(16B) wherein the at least one rotor comprises a cam;
(16C) wherein the at least one power supply is electrically coupled to the circular base, and wherein the at least one mobile power supply comprises an integral control interface operatively coupled to the at least one stator assembly,
wherein the at least one mobile power supply comprises at least one battery disposed within the circular base,
wherein the circular base comprises a cylindrical shape, wherein the integral control interface is configured to control a rotational speed of the at least one rotor and is configured to selectively control the rotational speed of the at least one rotor within each rotation of the at least one rotor, wherein the integral control interface is configured to selectively adjust the rotational speed of the at least one rotor within each rotation of the at least one rotor based on a circumferential orientation of the at least one rotor;
wherein the integral control interface is configured to selectively adjust the rotational speed of the at least one rotor from the first rotational speed at a first range of circumferential orientations of the at least one rotor to a second rotational speed at a second range of circumferential orientations of the at least one rotor; and
wherein the integral control interface is configured to selectively adjust the rotational speed of the at least one rotor from the first rotational speed corresponding to a first range of rotor angles to the second rotational speed corresponding to a second range of rotor angles.
