Patent ID: 7053508

Claim:
A rotor for a rotary electric machine, comprising: a predetermined number of main pole magnets, wherein each of the main pole magnets is magnetized so that its radial inside portion and its radial outside portion have opposite polarity of north pole and south pole from each other, and the main pole magnets are arranged in a circumferential direction so that each main pole magnet has its radial inside and radial outside polarities reversed from its closest main pole magnets; a predetermined number of yoke magnets disposed to allow magnetic flux to flow through circumferential surfaces of the main pole magnets; and a metal heat radiating member having heat conductivity, wherein the main pole magnets and yoke magnets are fixed in contact with the metal heat radiating member, and the heat radiating member includes a cylindrical portion surrounding outer peripheries of the main pole magnets and yoke magnets.
