Abstract
A rotor for a bearingless induction motor is provided. A rotor core defines rotor slots. A rotor winding includes a common connector plate, a plurality of rotor connector plates, and a slot conductor mounted within each rotor slot. The common connector plate is mounted adjacent a first end of the rotor core. The plurality of rotor connector plates is mounted adjacent a second end of the rotor core. Each slot conductor is electrically connected to the common connector plate and to one rotor connector plate of the plurality of rotor connector plates. Each rotor connector plate of the plurality of rotor connector plates is configured to connect a group of slot conductors that includes at least two slot conductors. A number of slot conductors included in the group of slot conductors is defined based on a predefined number of suspension pole pairs selected to provide a radial suspension force.
