ABSTRACT:
An artificial heart assembly, designed for implantation into a subject, which may be a total artificial heart or a ventricular assist device. The artificial heart assembly has a blood inlet conduit, a blood outlet conduit, a pumping mechanism for pumping blood from the blood inlet conduit to the blood outlet conduit, and a sensorless, DC brushless motor operatively connected to the pumping mechanism. The motor is reversibly driven in a first direction and a second direction, the motor changing between the first and second directions at a rate of at least 30 times per minute. The artificial heart assembly has means for periodically applying electrical signals to a plurality of the motor terminals while leaving at least one of the motor terminals unenergized, means for detecting a voltage at the unenergized motor terminal, and means for determining, based upon the voltage at the unenergized terminal, the angular position of the rotor with respect to the stator.
