Description
Overview:
This Genuine Makita Armature Assembly (515619-7) is a 240V motor rotor for compact Makita angle grinders, including the 9553NB and 9554NB. It is built around a laminated steel core with tightly wound copper coils and a precision-machined commutator to deliver smooth, efficient power transfer to the gearbox. A moulded black cooling fan is integrated on the shaft to move air through the motor housing and help manage heat during continuous use. The assembly restores performance where the original armature has worn, burned, or become noisy. Manufactured to Makita's specifications for fit and balance, it is designed to handle the rigours of site, workshop, and DIY work. Key dimensions: overall length 152 mm, body diameter 31.5 mm, fan (black wheel) diameter 56 mm, threaded end diameter 5.9 mm.
