Frequently Asked Questions

Q: How do I know which carbon brush size I need for my power tool motor?

A: Carbon brushes are specified by their three dimensions (width × thickness × length), such as 3×3×4.5mm or 5×5×10mm. Check your tool's original manual, the worn brush itself, or the manufacturer's parts list for the correct size. Using the wrong dimensions can cause poor contact, excessive sparking, and accelerated motor wear.

Q: What is the difference between a brushed and a brushless motor in power tools?

A: Brushed motors use carbon brushes and an armature (rotor) to transfer electrical current, making them straightforward to repair by replacing worn brushes or armatures. Brushless motors use electronic commutation via a stator coil assembly, offering higher efficiency, longer runtime, and less maintenance — but require replacing the entire stator or rotor assembly when damaged.

Q: Can I replace an armature rotor myself, or do I need a professional?

A: Many armature rotor replacements are DIY-friendly if you have basic mechanical skills and the correct tools. Always disconnect the tool from power before disassembly, take photos of the wiring before removal, and ensure the replacement armature matches the original's tooth count, shaft diameter, and bearing specifications (e.g., 608 or 626 bearings) for a proper fit.

Q: Are these motor parts compatible with major power tool brands?

A: Yes — our collection includes parts cross-referenced to popular brands such as Makita, Saeyang, and others. Always verify compatibility by matching part numbers, voltage ratings, and physical dimensions listed in each product description before purchasing.
