Claim Text:
1. A permanent magnet rotor comprising: a substantially cylindrical rotor core comprising an outer edge, an inner edge, and opposed first and second ends, said rotor further comprising a first wall and a second wall defining at least one radial aperture extending radially through said rotor core; at least one permanent magnet positioned within said at least one radial aperture; a first indentation formed in one of said at least one permanent magnet and said first wall, and a second indentation formed in the other one of said at least one permanent magnet and said first wall, wherein said first indentation is defined entirely between said inner edge and said outer edge, said first indentation defining a first space between said at least one permanent magnet and said radial aperture first wall, the first space extending between a radially inner end and a radially outer end, said first indentation including a first radius of curvature and said second indentation including a second radius of curvature larger than the first radius of curvature; and a first material located within said first space such that said first material is located entirely between said radially inner end and said radially outer end, said material configured to substantially prevent movement of said at least one permanent magnet relative to said at least one radial aperture.
