Original Makita armature (rotor) 619225-1 — the rotating motor assembly designed for Makita LXCU01 — restores the motor’s electrical and mechanical drive when the rotor commutator or windings are damaged.
This genuine Makita rotor is the correct replacement for the 18 V LXT handheld chainsaw family (commonly listed for BUC122 and DUC122 models) and installs in the existing motor housing to re-establish smooth commutation and shaft drive.
Bought as a single, serviceable component for a quick repair, the part is supplied as the complete armature assembly so you don’t need to swap individual windings — it mates with the tool’s original bearings and brush/commutator interfaces. Makita parts like this are intended to match the original fit and function.
If you need a reliable replacement rotor to get a BUC122/DUC122/LXCU01 back into service, this 619225-1 armature is the direct-fit power tool parts choice to restore motor rotation and cutting performance.
