Embodiment Construction
[0081] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0082] If the stator power winding and suspension winding are not considered, the cross-section of the bearingless flux switching motor is as follows: figure 1 shown. The stator is composed of 12 U-shaped magnetic cores and 12 pieces of permanent magnets. The permanent magnets are embedded between two adjacent U-shaped magnetic cores. The permanent magnets are alternately magnetized along the tangential direction of the circumference. The excitation directions are 12 as shown in the figure. Indicated by the black arrow. The rotor is a salient pole iron core structure with neither permanent magnets nor windings on it. exist figure 1 Power windings and suspension windings with different structures embedded in the stator core can form bearingless flux switching motors with different performances. However, after deducting the windings, the...
