Abstract
To improve resistance of a motor device against an organic solvent and to suppress degradation in performance of the motor device with time. In a motor device, an excitation magnet is formed using a hollow-cylinder shaped anisotropic bonded magnet. This bonded magnetis press-fitted in a housingand is held. The bonded magnetis formed of a hollow-cylinder shaped anisotropic rare earth bonded magnet which is obtained by compounding an anisotropic rare earth magnet powder with a phenol-novolac type epoxy resin, followed by molding. The anisotropic rare earth bonded magnetis press-fitted along an inner peripheral portion of the housing, and on an exposed surface layer of the anisotropic rare earth bonded magnet press-fitted in the housing, a coating layer is formed by an infiltration treatment using a polyamide-imide-based resin.
