Rotor-stator structure for electrodynamic machines

While the rotator * stator structure for an electric machine especially raising the torque and/or efficiency of per a unit size (or unit weight), in order that a manufacturing cost may be lowered, path length of magnetic flux is made into the minimum, and it is indicated in order to delete back iron. Illustration rotator * stator structure can be equipped with the shaft which defines the axis of rotation, and the rotator by which at least two magnets are attached on the shaft in 1 enforcement form. Two magnets may be magnets of the pillar form or cone which has the magneto surface which faces an air gap. In some enforcement forms, a straight line-like field pole component can be substantially arranged on the same axle, and these field pole component can have the magnetic flux interaction surface formed in the both ends of these field poles. These surfaces were adjoined and located in the faced magneto surface, and the functioning air gap which is the form curved in general is defined. [Selection figure] Fig. 2B
