Original Makita armature assembly (part no. 516214-6) designed to restore motor performance in Makita sheet/orbital sanders. This replacement rotor assembly includes copper windings on a laminated steel core, a precision-machined commutator and integral cooling fan so the motor runs smoothly with reduced sparking and vibration — a direct-fit swap for the 9046 orbital sander (240 V variant).
Key details
- Part number: 516214-6 (armature assembly / rotor).
- Intended fit: Makita 9046 orbital (sheet) sander — specifically the 240 V configuration listed for that model.
- Construction: copper-wound rotor, laminated steel core, machined commutator, integrated fan and precision balancing for steady operation under load.
- Sold as a single complete armature assembly ready to install in the correct model.
Fitment note
- This part number is the 240 V armature for the 9046; the 110/120 V version for the same model uses a different Makita armature part number (for example, 516211‑2 is listed as the 110 V variant). Confirm your tool’s model and voltage before ordering.
Why it’s useful
- If your 9046 is showing heavy sparking, low power, or excessive vibration, replacing the armature with this original Makita assembly returns the motor to factory spec and lets the sander perform as designed.
What’s included
- One original Makita armature assembly (516214-6), ready for direct replacement where specified.
(Please ensure the 9046 model and voltage match your tool before fitting.)
