Claims27
A rotor of a rotating electric machine comprising:
- a support having a generally discoid shape for mounting the rotor on a shaft, and
- a plurality of magnetic segments that are fastened onto the support such that the segments are disposed on two axially opposite faces of the support,
- wherein an outer periphery of the support has notches that are superposed axially with notches of the segments.
A rotor of an alternator exciter, comprising:
- a support for mounting the rotor on a shaft, and
- a plurality of magnetic segments that are fastened onto the support such that the segments are disposed on two axially opposite faces of the support,
- wherein an outer periphery of the support has notches that are superposed axially with notches of the segments.
A method for manufacturing a rotor, the rotor including:
- a support having a generally discoid shape for mounting the rotor on a shaft, and
- a plurality of magnetic segments that are fastened onto the support such that the segments are disposed on two axially opposite faces of the support,
- wherein an outer periphery of the support has notches that are superposed axially with notches of the segments,
- the method comprising:
- cutting a strip of segments from a magnetic plate,
- bending the strip, and
- fastening the strip onto the support.
