Original Makita magnet-field (stator) assembly — part number 632J71-5 — designed for 18 V Makita cordless drills and impact drivers. This unit is the stationary magnetic field component that sits around the armature and provides the motor’s field; the listed weight is about 138 g and it’s supplied as the complete stator/magnet field assembly for direct replacement.
Fits a range of Makita 18 V models, for example: BDF441, BDF442, BDF446, BDF451, BDF452, BDF456, DDF446, DDF451, DDF456 and the BHP series BHP441, BHP446, BHP451, BHP456. Use this original Makita stator when restoring proper motor function in the compatible model list.
If your tool’s motor shows intermittent power, burning smell, or no rotation while the armature spins freely, replacing the 632J71-5 magnet field (stator) is a straightforward repair — the part is made to match Makita’s original fit and connectors so it installs in the same cavity without machining. This genuine Makita component is the right choice when you want a reliable replacement among parts for power tools.
