Makita Genuine 515616-3 Armature Assembly (110V) for Makita 9553NB. 9554NB, 9555NB Angle Grinder

The Makita 515616-3 Armature Assembly is a genuine OEM spare part designed to restore motor performance in Makita 9553NB, 9554NB, and 9555NB compact angle grinders operating on 110V site power supplies. As the rotating core of the motor, the armature is subject to heat, load, and mechanical wear over time. This replacement assembly features copper windings on a laminated steel core, a precision-machined commutator, and an integral cooling fan — the same configuration as the original component it replaces. When the existing armature shows signs of wear, arcing, or reduced power output, fitting a genuine replacement helps restore smooth, consistent performance across cutting, grinding, and deburring applications. Specified for 110V use only, this armature is wound for tools running from UK site transformers and is not compatible with 240V variants. Contractors and maintenance technicians working on-site will find this an essential stocking part for minimising grinder downtime. Installation is straightforward using standard workshop tools, and service life is further extended when the part is fitted alongside serviceable brushes and a clean motor housing.
