Description
Overview:
This genuine armature (MPN 647864-03SV) is an OEM DeWalt (Black & Decker) motor component for corded hammer drills such as the DWD522KS and DWD530KS. It is built with a laminated steel core, precision‐wound copper coils, a multi‐segment copper commutator and an integrated cooling fan to deliver smooth, efficient rotation under load. The armature is the rotating part of the motor that drives the chuck and hammer mechanism; replacing a worn or burnt rotor restores power, reduces sparking and helps keep speed and torque consistent. Manufactured to original tolerances for balance and durability, it is suitable for regular trade use and workshop repairs. Supplied as a direct‐fit part, it helps extend tool life and maintain reliable drilling performance in masonry, timber and metal.
