Abstract
An improved yet relatively inexpensive motor is provided by mounting commercially-available magnets together with pole pieces to the interior surfaces of the housing of a motor. The pole pieces are then shaped in part, in situ, so as to form a cylindrical space between the pole pieces. A rotatable armature assembly and a stationary, magnetically-conductive core member are mounted within the cylindrical space formed by the shaped pole pieces with the armature assembly being radially-spaced from and disposed between the pole pieces on the one hand and the core member on the other hand.
