ABSTRACT:
An electrical machine using a plurality of separate teeth that can be axially inserted into a stator ring or armature after receiving a bobbin or form wound coil. Each tooth contains a primary locating structure and a secondary locating structure which respectively set the radial position and the angular position of the teeth in a stator ring. This construction can also be used with internal motor armatures. The primary and secondary locating structures have a size equal to or smaller than the portion of the tooth that holds the coil. This allows insertion of a pre-wound coil over these features without interference. The use of separate stator or armature teeth that are press fitted into the stator ring or armature allows the use of coil types that could not be inserted into a one piece stator or armature and tooth materials with optimum magnetic properties.
