1. A method of operating a blood pump, the method comprising:
controlling, via a controller, supply of drive currents to drive coils of the blood pump to magnetically rotate an impeller around an impeller axis of rotation within a blood flow channel of a blood pump, wherein rotation of the impeller pumps a flow of blood through the blood pump; and
controlling, via the controller, supply of a bearing current to a levitation coil of the blood pump to magnetically levitate the impeller in a direction transverse to the impeller axis of rotation so as to minimize power consumption of the blood pump during operation of the blood pump.
