Traction Motor parts and their functions

5 top-level parts · 28 parts in total · full bill of materials below

#	Part	Qty	What it does
1	Stator Assembly 3 parts	1×	Stationary part of an electric motor: a slotted laminated core wound with copper coils that produce the rotating magnetic field.
2	Rotor Assembly 4 parts	1×	Rotating member of an electric motor: a laminated steel core carrying permanent magnets or conductor bars, pressed onto a shaft that delivers the torque.
3	Copper Winding	3×	Insulated copper conductor wound into coils that carry the phase current and create the magnetic field in a motor, generator, or transformer.
4	Motor Housing	1×	Cast or extruded aluminium shell that carries the stator, locates the bearings, and conducts heat away from an electric motor.
5	Ball Bearing	2×	Deep-groove radial ball bearing.
