Description
Overview:
This Genuine Makita armature assembly is a 110 V rotor for the JR3050T reciprocating saw, supplied under manufacturer part number 518646-3. The armature is the rotating core of the motor and is built around a laminated steel stack with tightly wound copper coils and a precision-machined commutator. Its job is to convert electrical energy into the torque that drives the saw, restoring smooth running and full power when the original part is worn or damaged. Designed for 110 V tools commonly used with site transformers in the UK, this OEM component maintains the correct clearances and balance required for reliable operation. If your JR3050T is showing reduced power, excessive sparking, or rough running, replacing the armature can return the tool to dependable service.
