Anisotropic magnet brushless motor having a rotor with elastic insulating support structure

1. Field of the Invention A permanent-magnet type brushless motor has a rotor which is made by integrally forming a rotating magnetic pole comprising a cylindrical multi-pole anisotropic magnet, a shaft and an elastic insulating supporting member having rigidity lower than at least that of the shaft. The multi-pole anisotropic magnet causes its magnetic flux to flow to form the closed magnetic circuit, thereby eliminating the necessity of forming the closed magnetic circuit using an inner stator core in the magnet required for the radial anisotropic magnet. A cylindrical casing holding therein a stator core.
