This paper deals with the validation and implementation of a bearingless drive for high speed applications up to 100krpm. To achieve the bearing forces and the drive torque this motor is equipped with 6 toroidal coils that promised, based on previous optimizations, higher power densities than an earlier implemented 5-phase configuration. The rotor of the… CONTINUE READING
