A winding design approach is proposed for the bearingless ac homopolar and consequent pole motors that utilizes the same coils for both suspension force and torque production. This enables a “pure” bearingless motor design, where the same iron and copper are used for both magnetic bearing operation and torque production, and can result in more optimal machine performance. Separate terminal connections...
Winding layouts for the bearingless ac homopolar and consequent pole motors that allow the same coils to be used for both radial force and torque production are investigated. This concept enables a “pure” bearingless motor where the same iron and copper are used for both magnetic bearing operation and torque production. For three phase windings, it is shown that these schemes limit 6-pole machines...
