1. A system controller for driving a blood pump comprising an impeller sealed within a pump housing and hydrodynamically suspended in the pump housing, wherein the impeller comprises a plurality of magnets, the blood pump comprising a plurality of stator coils in a brushless direct current (DC) motor that, when driven by a plurality of drive signals, make the impeller rotate within the pump housing, wherein the system controller comprises:
an electrical connector for electrically connecting the system controller to the blood pump to provide the plurality of drive signals from the system controller to the plurality of stator coils in the brushless DC motor in the blood pump;
a display;
a control processor that provides management functions for the system controller and that displays at least one message on the display; and
a programmable logic device that provides field-oriented control of the brushless DC motor in the blood pump by providing the plurality of drive signals to the plurality of stator coils in the brushless DC motor in the blood pump via the electrical connector, wherein the programmable logic device is configured to continue providing the plurality of drive signals when the control processor stops working.
