"To provide a field magnet with permanent magnets capable of preventing surplus adhesive from being forced out and dropping from the peripheral edges of the permanent magnets when permanent magnets are bonded on the inside circumferential surface of the stator case (yoke), and the forced out adhesive from projecting radially inwardly from the permanent magnets, and suitable for using thin permanent magnets of high magnetic flux density in particular. A field magnet motor with permanent magnets bonded fixedly on the inside circumferential surface of a stator case of approximately a cylindrical shape, wherein there are provided the stator case formed, in its inside circumferential surface, with a first annular groove, and the permanent magnets bonded fixedly on the inside surface of said stator case with adhesive supplied from said first groove, with their edges parallel to and partly covering said first groove."
