Abstract: Radially oriented ring-shaped preliminarily molded pieces of a ring magnet are stacked in an axial direction to form a ring-shaped molded body, in which end faces of the ring-shaped preliminarily molded pieces are bonded together. This ring-shaped molded body is sintered and heat-treated to produce the ring magnet. Ring magnets which are less susceptible to deterioration of magnetic properties due to a disturbance of magnetic orientation near lamination boundary surfaces are produced. The invention provides a method of manufacturing such ring magnets with high efficiency.

Abstract: A sintered ring magnet (10) is produced through processes of magnetically orienting magnetic powder by applying a magnetic field, pressing the magnetic powder and sintering a ring-shaped powder compact (30) thus formed. The sintered ring magnet (10) has a generally cylindrical outer surface with surface corrugations formed by alternating hollows (11) and protrusions (12) at regular intervals around the sintered ring magnet (10) at least in part along an axial direction thereof, wherein the sintered ring magnet (10) varies in cross-sectional shape from one position to next along the axial direction, and magnetic poles are formed along the surface corrugations with boundaries of the magnetic poles located in the hollows (11). The hollows (11) and the protrusions (12) are skewed about a longitudinal axis of the sintered ring magnet (10). The surface corrugations are shaped into a wavy pattern expressed approximately by absolute values of a sine wave.
