surface 32 and an interior annular surface 34 see fig2 is created as illustrated in fig2 the interior annular surface 34 also includes a first hook like protrusion 35 and a second hook like protrusion 37 each of which project inwardly towards the center of shaft 17 supporting armature windings 19 the first protrusion 35 is used to support the first coil 20 while the second protrusion 37 is used to support the second coil 22 as is commonly known each of the first protrusion 35 and the second protrusion 37 include pole tips 39 that define kidneys 41 the lower housing 16 best seen in fig1 and 3 may be coupled to the upper housing 24 using a bracket 19 partially shown in fig3 and includes structure to receive current from the coils 20 22 and carry it to and from the armature 26 the lower housing 16 may be made of a non conductive material for example a thermoplastic such as a glass filled polyester the lower housing includes a first brush housing 64 and a second brush housing 66 disposed within each brush housing 64 66 is an electrically conductive brush 65 67 which is urged usually by a spring loaded member 69 radially inward toward shaft 17 and the armature 26 as is known in the art the brushes 65 67 transmit current to the rotating armature 26 through the commutator 28.
