Abstract
A motor and fan structure includes direct current motor assembly having a stator assembly including a flux plate and permanent magnet structure mounted on the flux plate . The flux plate defines one end of the motor assembly and define a magnetic flux path of the motor assembly. The motor assembly also includes a generally cylindrical armature assembly defining another end of the motor assembly. The armature assembly is radially wound with windings , 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 having a generally cylindrical hub receiving and covering the outermost part and the portion of the windings of the armature assembly. The hub has a plurality of blades 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.
