Abstract
An axially turnable rotor for an electric generator. In one embodiment, a rotor coil is encased within two pole piece members each having a plurality of flanged magnetic poles extending from a flat base face. Each of these flanged magnetic poles has a retaining structure on the opposite end from the flat base face. In the preferred embodiment of the invention, this retaining structure takes the form of a subflange. When the two pole piece members are meshed together around the rotor coil, the subflanges of each pole piece member extend beyond the flat base face of the opposing pole piece member, allowing for the introduction of a ring or other securing means upon the subflanges.
Claims23
An axially turnable rotor for an electric generator, said rotor comprising:
- a rotor coil;
- a pole piece assembly made up of a first pole piece member and a second pole piece member, each of said members having flanged magnetic poles alternatively meshed with each other and encasing said rotor coil, at least two of said flanged magnetic poles including a distal end defining a retaining structure thereon, said pole piece members including a base face axially opposite said distal ends;
- and
- means for securing said flanged magnetic poles via said retaining structures, wherein one of said retaining structures contacts only the first pole piece member and a second of said retaining structures contacts only the second pole piece member.
A rotor for an electric generator, said rotor comprising:
- a rotor coil;
- a pole piece having flanged magnetic poles encasing said rotor coil, said pole piece member including a base face axially opposite said distal ends;
- at least two of said flanged magnetic poles including a distal end defining a retaining structure thereon;
- and
- means for securing said flanged magnetic poles via said retaining structures by contacting only one pole piece member.
An axially turnable rotor assembly for an electric generator, said rotor comprising;
- a rotor coil;
- a pole piece assembly made up of a first pole piece member and a second pole piece member, each of said members having flanged magnetic poles alternatively meshed with each other and encasing said rotor coil;
- and
- a plurality of magnetic poles on each of said pole piece members rigidly secured to each other with retaining structures at distal ends thereof to prevent radial deformation of said poles during rotation of said rotor, wherein one of said securing retaining contacts only the first pole piece member and a second of said securing retaining contacts only the second pole piece member.
An axially turnable rotor for an electric generator, said rotor comprising:
- a rotor coil;
- a pole piece assembly made up of a first pole piece member and a second pole piece member, each of said members having flanged magnetic poles alternatively meshed with each other and encasing said rotor coil, said pole piece members including a base face axially opposite said distal ends;
- at least two of said flanged magnetic poles including a distal end defining a subflange on said distal end, said subflange defining radially facing stepped portions;
- and
- a plurality of rigid metal rings adapted to fit said subflanges on at least two distal ends, each contacting at least two of said distal ends of only one pole piece member and not in contact with said flanged magnetic poles of said other pole piece member.
