Abstract
A structure of an armature of a toroidal winding type rotating electric machine, such as a motor or generator, which constitutes at least a member of a stator or a rotor is disclosed. The structure comprises a laminated core having an annular core portion and a facing core portion that extends from the annular core portion toward an opposing machine member. A coil is wound with a toroidal winding about the annular core portion of the laminated core. A partial laminating core is laminated on the facing core portion of the armature to enlarge the facing surface opposite the opposing machine member. The total lamination thickness of the facing core portion and partial laminating core portion is larger than the thickness of the annular core portion.
Claims26
A structure of an armature of a rotating electric machine, which constitutes at least a member of a stator or a rotor, comprising:
- a laminated core having an annular core portion and a facing core portion that extends from said annular core portion toward an opposing machine member, said annular core portion and said facing core portion being integrally formed;
- a coil being wound with a toroidal winding about said annular core portion of said laminated core;
- a partial laminating core being laminated on said facing core portion of said armature to enlarge a facing surface opposite said opposing machine member, said partial laminating core being laminated in a shape that continuously extends from said facing core portion to at least said annular core portion;
- and
- wherein a total lamination thickness of said facing core portion and said partial laminating core is larger than a thickness of said annular core portion, and a thickness of said facing core portion and said partial laminating core being the same.
The structure of an armature of a rotating electric machine wherein a partial laminating core is laminated in layer over core portions other than winding portions of a lamination core in which a coil is wound around an annular core portion with a toroidal winding, a topmost surface of said partial laminating core is made to be a magnetic-facing surface which axially faces a secondary member constituting an opposing machine said partial laminating core being laminated in a shape that continuously extends from the topmost surface of said partial laminating core to at least said annular core portion, said annular core portion and said partial laminating core being integrally formed, and a thickness of a facing core portion and said partial laminating core being the same.
