Abstract: A motor and fan structure 10 includes direct current motor assembly 18 having a stator assembly 20 including a flux plate 22 and permanent magnet structure 24 mounted on the flux plate 22. The flux plate 22 defines one end of the motor assembly and defines a magnetic flux path of the motor assembly. The motor assembly also includes a generally cylindrical armature assembly 32 defining another end of the motor assembly. The armature assembly is radially wound with windings 40, and an outermost part of the armature assembly and at least a portion of the windings is exposed to the environment. The structure includes a fan 12 having a generally cylindrical hub 14 receiving and covering the outermost part and the portion of the windings of the armature assembly. The hub 14 has a plurality of blades 16 extending therefrom. Thus, the weight and axial length of the motor assembly can be reduced since no case is required to cover the armature assembly yet the armature assembly is protected by the fan hub.

Abstract: A stator assembly (16) for a brush-type permanent magnet DC motor includes a stator body (17) having a central axis A and an annular inner wall (20) disposed about the central axis. The inner wall has at least one raised portion (21) and at least one recess (22) adjacent to the at least one raised portion. The raised portion defines a flux recovery feature. At least one permanent magnet (18) is disposed within the recess (22) such that an inside radius IRM of the magnet is substantially the same as, and concentric with, an inside radius IRF of the raised portion as measured from the central axis, with the flux recovery feature (21) and magnet (18) defining a magnetic circuit. In section, the at least one raised portion is joined with a surface defining the at least one recess by a generally S-shaped structure thereby defining a curved transition there-between. Thus, in a motor having N poles, only N/2 magnets are required.
