EC Motor parts and their functions
8 top-level parts · 128 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 | Neodymium Magnet | 8× | Rotor magnets |
| 4 | Motor Shaft | 1× | A hardened steel shaft, typically 8–12 mm, carrying the impeller on one end and riding in sealed deep-groove bearings. |
| 5 | Ball Bearing | 2× | Sealed for life |
| 6 | Motor Housing | 1× | Cast or extruded aluminium shell that carries the stator, locates the bearings, and conducts heat away from an electric motor. |
| 7 | Hall Sensor | 3× | Commutation feedback |
| 8 | Integrated Drive Electronics 5 parts | 1× | Integrated inverter |
