Abstract
A bearingless split tooth flux-reversal motor (FRM) for use with a pump, such as a centrifugal blood pump. In some embodiments, the motor has a magnet-free rotor and a magnetic configuration wherein the force generation is independent of the rotor angle, allowing for simple radial force generation using stator-fixed currents. The motor torque can be generated using commutated two-phase currents.
