Abstract:
A motor system can include a bearingless stator having a plurality of magnetic windings including rotation windings and suspension windings; a dipole interior permanent magnet (IPM) rotor positioned within the stator, the rotor having a plurality of permanent magnets disposed within a cylindrical structure; one or more position sensors to measure radial and angular position of the rotor; and a controller configured to receive measurements from the one or more position sensors and to generate current commands for the stator to excite the rotation windings to generate torque and to excite the suspension windings to stabilize the rotor within the stator.
