Document Type and Number:
WIPO Patent Application WO/2006/051934
Kind Code:
A1
Abstract:
A surface magnet type motor (10) has a magnet (16) on the surface of a rotor (15). The motor has an anti-scattering tube (17) of a cylindrical shape having a length greater than the axial direction length of the magnet (16) arranged on the rotor (15) and containing the magnet with a pressure so as to prevent scattering of the magnet. The motor also has a stress mitigation unit for mitigating the stress caused at the end portion of the magnet (16) contained in the anti-scattering tube (17) with a pressure.
