[Part Name] Field Assembly [Description] Components providing power for the motor to rotate and consists of a stationary coil housing and stationary coil [Manufacturing] The housing is machined for maximizing cost and time efficiency and the coil is shaped to fit inside the housing. [Reason for Using Materials] Steel is used to steadily hold the coil in place and copper is used because of its efficiency in conducting electricity. [Forces Applied] none [Functional/Cosmetic] This part is purely functional as it houses the armature as well and provides power to the blade. [Quantity] 1 [Complexity] 4 [Reason for Shape] 
The housing is fairly cubical in shape which has a cylindrical hole in its center to properly house the armature and deliver a magnetic field.
