They are arranged by model and orientation:
- Left Column (Black holders): Standard rectangular plastic housings, likely 5mm x 13.5mm or similar common dimensions. Notice the “L” (Left) and “R” (Right) orientations molded into the plastic casings near the bottom of that row, which ensure proper contact angle with the armature.
- Top Right Column (Black slim holders): A different mounting design, featuring a centered screw tab and a distinct terminal connection layout.
- Bottom Right Column (Green holders): Typically associated with specific motor manufacturers (such as Ceset or Sole motors frequently used in European washing machines).
Common Technical Specifications to Verify
When replacing or cataloging these parts, you generally look for:
| Parameter | Description |
| Dimensions | Thickness $\times$ Width $\times$ Length of the carbon stick (e.g., $5 \times 13.5 \times 35\text{ mm}$ or $5 \times 12.5 \times 36\text{ mm}$). |
| Angle | The bevel angle at the tip of the carbon where it meets the commutator. |
| Casing Type | The configuration of the plastic holder, placement of the mounting pins/holes, and the type of electrical terminal (4.8mm or 6.3mm spade). |
