Gearless Traction Machine parts diagram: 1 stator assembly, 2 rotor assembly, 3 copper winding, 4 motor housing, 5 neodymium magnet, 6 ball bearing, 7 oil seal, 8 traction sheave, 9 disc brake. 65 parts in 9 top-level items. — Gearless Traction Machine parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	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	6×	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	Neodymium Magnet	24×	PM rotor poles
6	Ball Bearing	2×	Shaft support
7	Oil Seal	2×	Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
8	Traction Sheave	1×	Grooved drive sheave
9	Disc Brake 3 parts	1×	Fail-safe disc brake
