Abstract: A system and a method for starting a rotor of an implantable blood pump are described. For example, a blood pump system includes a rotary motor having a stator and a rotor. The rotor has permanent magnetic poles for magnetic levitation of the rotor, and the stator has a plurality of pole pieces arranged circumferentially at intervals. The blood pump system includes a controller configured to control a start phase of the rotor, wherein the start phase is prior to the rotor being positioned in a predefined geometric volume for pumping blood and wherein the start phase includes performing a rotation of the rotor by an angle larger than an angle corresponding to a quarter of an angular distance between two neighboring magnetic poles of the rotor.
