Abstract
The alternator rotor includes a polygonal shaped rotating core defining a plurality of flat faces. A plurality of polygonal shaped permanent magnets cooperate with the flat faces of the core. The permanent magnets form voids between adjacent permanent magnets. A plurality of titanium or titanium alloy filler pieces is positioned, respectively, in the voids created between adjacent permanent magnets. A compressive outer sleeve encloses the core, permanent magnets, and titanium filler pieces to form the alternator rotor.
Claims16
An alternator rotor, comprising:
- a rotating core defining a plurality of core faces;
- a plurality of permanent magnets cooperating with the core faces, with the permanent magnets defining voids between adjacent permanent magnets each of said permanent magnets have a plurality of permanent magnet faces, a respective permanent magnet face of each of the permanent magnets cooperating with a respective core face;
- a plurality of titanium filler pieces positioned, respectively, in the voids defined between adjacent permanent magnets;
- and
- a compressive outer sleeve enclosing the core, permanent magnets, and titanium filler pieces.
A method of assembling an alternator rotor, comprising the steps of:
- providing a rotating core defining a plurality of flat faces;
- arranging a plurality of permanent magnets around the core, with the permanent magnets having flat faces cooperating with the flat faces of the core, and with the permanent magnets defining voids between adjacent permanent magnets;
- positioning a plurality of titanium filler pieces in the voids defined between adjacent permanent magnets;
- and
- enclosing the core, permanent magnets, and titanium filler pieces with a compressive outer sleeve.
A method of retrofitting corner filler pieces in an existing alternator rotor, comprising the steps of:
- providing an existing alternator rotor having a central core, permanent magnets arranged around the central core, corner filler pieces separating adjacent permanent magnets, and an outer sleeve, with the outer sleeve enclosing the central core, permanent magnets, and corner filler pieces;
- and
- removing the existing corner filler pieces and replacing the existing corner filler pieces with titanium filler pieces.
