Claims20
A stator iron core of an electric motor comprising:
- plural magnetic pole segments connected and confronted by plural confronting surfaces,
- wherein two of the confronting surfaces respectively include a V-shaped projection and a V-shaped recess, and wherein said V-shaped projection and V-shaped recess form a jut-point portion projecting in a radial direction to an outer circumference side thereof.
A stator core, comprising:
- a first pole segment defining a projection an a first void adjacent the projection;
- and
- a second pole segment defining a recess and a second void adjacent the recess, the recess configured to receive the projection.
A stator core, comprising:
- a first pole segment defining a projection;
- and
- a second pole segment defining a recess configured to receive the projection,
- wherein one of the first and second segments defines a void adjacent the projection or the recess on an outer circumference of the pole segments when the projection is disposed in the recess.
