Dewalt n381700 Armature 120 Volts

Product Description

The DEWALT n381700 is a 120-volt replacement armature designed for use in compatible DEWALT power tools. The armature is the rotating electromagnetic component at the core of a universal motor, converting electrical energy into the mechanical rotation that drives the tool. When an armature fails due to winding burnout, commutator wear, or physical damage, the tool loses power or stops running entirely. Replacing the armature restores full motor function without requiring a full tool replacement. This part is installed by power tool repair technicians and experienced service professionals.

This armature is rated for 120-volt AC power, making it suited for standard North American electrical supply. It is intended for bench or field service repairs on DEWALT tools that use a universal motor configuration. Typical applications include restoring saws, grinders, routers, or similar corded tools to operational condition. Refer to the tool model documentation to confirm this armature applies to the specific unit being serviced before ordering.
