OVERVIEW

Genuine OEM Field Coil for Walter Power Tools

The Walter 48L452 Field Coil Assembly is a precision-engineered electrical component designed to serve as the stator in specific Walter Surface Technologies power tool motors. As the stationary part of the universal motor system, the field coil is responsible for generating the strong magnetic field required for the armature to rotate and produce torque. This assembly is constructed using high-grade copper wire wound around a laminated iron core, designed to minimize energy loss and maximize magnetic flux density.

Over time, the harsh conditions of industrial environments—including excessive heat, dust ingress, and vibration—can degrade the insulation of a field coil, leading to short circuits or open windings. A compromised field coil often results in a significant loss of power, excessive sparking at the commutator, or complete motor failure. Replacing a damaged unit with the genuine 48L452 assembly ensures that the electrical characteristics of the motor remain balanced. This part is manufactured to Walter's exact specifications, ensuring the correct impedance and physical fitment within the tool housing.

Professional repair technicians understand the importance of using OEM parts for electrical repairs. The 48L452 features robust insulation varnish and secure termination points to handle the high currents typical of heavy-duty grinding and finishing applications. By restoring the magnetic integrity of the motor, this field coil helps maintain the tool's RPM under load and prevents damage to other components like the armature and carbon brushes. It is an essential spare part for maintenance departments and repair shops servicing Walter equipment.

Key Technical Aspects:

  • Core Construction: Laminated steel to reduce eddy currents and heat buildup.
  • Winding Quality: High-conductivity copper with thermal-resistant enamel.
  • Fitment: Direct replacement for specific Walter tool models (verify via parts diagram).
  • Function: Generates the stationary magnetic field for motor rotation.

FAQ

The field coil acts as the stator in the electric motor, creating the magnetic field necessary for the armature to spin and power the tool.

Symptoms include the motor humming but not turning, excessive sparking at the brushes, the tool running very hot, smoke, or a burning smell.

Yes, the 48L452 is a genuine OEM replacement part manufactured by Walter, ensuring exact fit and performance.

No, it is designed for specific models. Please check your tool's parts diagram or manual to confirm the part number 48L452 matches your machine.

Installation requires disassembling the tool's motor housing. If you are comfortable with tool repair and electrical safety, it can be done; otherwise, professional service is recommended.

No, this is only the field coil (stator). The armature (rotor) is a separate component.

Common causes include overheating from overloading the tool, abrasive dust damaging the insulation, or general wear and tear over time.

Typically, you will need screwdrivers (Phillips or Torx), possibly a wrench for the spindle, and pliers for wire connections.
