input: [0] 120V Armature [1] 1 [2] 1 [3] Works in conjunction with the 120V field to convert the electric energy input into rotational energy that is utilized by the saw blade. [4] Steel, rubber, copper [5] Steel for its durability, copper wire for its conductivity, and rubber for its unique properties. [7] Cost effective and efficient for the complexity of the part and to get the desired properties. [6] 
output: Steel lathed down and machined to introduce the ridges on sides. Wires were extruded and balled into a sphere using a guided winding process
