Abstract
Methods of operating a blood pump having a magnetically levitated impeller. A method of operating a blood pump includes controlling 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. Supply of a bearing current to a levitation coil of the blood pump is controlled 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.
