Original Makita armature / rotor assembly, part no. 517649-4 — a direct replacement rotor (armature assy) for Makita mains grinders and related models.
The armature is specified for the 240 V versions and is used in several compact Makita angle grinders — commonly listed for GA4030, GA4530 and GA5030 / GA4534 / GA5034 and the plate joiner PJ7000.
Fits the standard wheel sizes for those models (100 mm, 115 mm and 125 mm depending on model), so it replaces the worn or damaged rotor inside the motor assembly and restores proper commutation and shaft rotation when the original armature has failed.
Supplied as the assembled armature (shaft, commutator and fan/rotor assembly), ready for installation following the service/disassembly steps in the Makita parts manual — a straightforward swap if your grinder shows burned windings, heavy sparking at the commutator, or loss of power.
Part number: 517649-4 — genuine Makita armature/rotor assembly for the models listed above.
