ABSTRACT:
In a brush motor comprising a stator assembly constituted by a permanent magnet assembly and a cylindrical yoke, a stator provided with coils diametrically opposing to each other and rotatably disposed within the stator assembly, and a brush, the permanent magnet assembly is constituted by two arc segment magnets each having magnetic anisotropy in a radial direction and an arc angle .theta. of 170.degree.-180.degree., so that the permanent magnet assembly has a magnetic flux density distribution having a smooth wave form substantially free from localized deformations in a circumferential direction approximately on an inner surface thereof. Such an arc segment magnet is manufactured by a wet molding method and sintering.
