Description
Dewalt Ring 60325-01D
Technical Specifications Precision stamped laminated silicon steel stator core; matched field coil winding; designed for Dewalt motor voltage and power rating; mechanical mounting features matching Dewalt tool housings; insulation rated for power tool cyclic operation.
Functional Features Generates stationary magnetic flux when electric current passes through the field windings. Interacts with the rotating armature magnetic field to produce mechanical torque. Supports the high transient current loads encountered during power tool startup and heavy cutting operation. Provides mechanical mounting structure for brush holder assemblies in brushed motor variants.
Application Scenarios Dewalt portable electric power tools including angle grinders, hammer drills, rotary hammers and corded impact wrenches matching this part number.
Performance Parameters Low core magnetic loss; high winding insulation breakdown voltage; stable magnetic output under rapid thermal cycling; mechanical rigidity under high speed motor vibration.
Material Composition Stator core uses grain oriented silicon steel laminations; field winding wire is high temperature magnet wire; coil insulation is thermosetting varnish; mounting brackets are stamped carbon steel; insulating spacers are heat resistant thermoset plastic.
Structural Characteristics Annular ring shaped laminated stator core with integrated winding bobbins; molded coil assemblies secured within the core stack; mounting holes and registration features for positioning inside the power tool motor housing.
Working Principle When current flows into the field ring windings, the laminated iron core concentrates magnetic flux and creates a stationary magnetic field. The magnetic field interacts with the energized armature conductors to produce torque and drive rotor rotation. Commutation via carbon brushes switches armature current direction to maintain consistent rotation direction.
Installation Requirements Disassemble the power tool motor housing following Dewalt service procedures. Align the field ring registration features to the motor housing locators. Route field lead wires through designated strain relief channels. Reassemble brush holder and armature components and verify free rotation before power testing.
Precautions for Use Do not scratch or nick the enamel insulation on field coil wires during installation. Confirm the replacement part matches the exact Dewalt tool model. Check for short circuits between winding and stator core with an ohmmeter before reassembly.
