setting a first initial location of a first Hall sensor within an electric motor of a drive system that is configured to drive the total artificial heart;
setting a second initial location of a second Hall sensor within the electric motor of said drive system that is configured to drive the total artificial heart system;
establishing an initial offset between the first and second initial locations of the first and second Hall sensors;
initiating operation of the electric motor;
monitoring locations of the first and second Hall sensors;
identifying when an offset between said locations has altered from the initial offset; and
at least one of increasing and decreasing an electrical current to the electric motor in order to adjust a value of the offset to a desired value.
