OVERVIEW

Restore Peak Performance with Genuine Walter Parts

The Walter Field Coil Assembly (SKU: 48L377) is a critical OEM replacement component designed specifically for the maintenance and repair of Walter Surface Technologies power tools. As the stationary component of the universal motor system (the stator), the field coil is responsible for generating the strong magnetic field required to spin the armature. Over time, heavy industrial use, excessive heat, and the ingress of conductive abrasive dust can degrade the insulation of the field windings, leading to short circuits, loss of power, or complete motor failure. Replacing a compromised field coil with this genuine Walter part ensures your equipment operates at the efficiency and safety levels intended by the manufacturer.

Constructed with high-grade copper wiring and encapsulated in a durable, heat-resistant resin or varnish, this assembly is built to withstand the rigorous demands of metalworking environments. The insulation is specifically formulated to resist the abrasive particulate matter that often bypasses air filters in angle grinders and finishing tools. By maintaining the correct electrical resistance and magnetic properties, the 48L377 protects other sensitive components in the tool, such as the carbon brushes, commutator, and speed control electronics, from excessive wear or voltage spikes.

Professional repair technicians understand that substituting motor internals with non-OEM parts can lead to imbalances, increased vibration, and reduced torque. This Walter Field Coil Assembly guarantees a precise mechanical fit within the tool housing and correct electrical alignment with the armature. Whether you are performing a routine overhaul or troubleshooting a burnt-out motor, this part provides the reliability professionals expect from Walter Surface Technologies.

Technical Specifications & Compatibility

This assembly includes the wound copper coils, the laminated iron core stack, and the necessary lead wires for connection to the switch and brush holders. It is designed for specific voltage and amperage ratings corresponding to Walter's industrial tool lineup. Please verify your tool's model number and schematic to ensure the 48L377 is the correct part for your specific machine before installation.

FAQ

The field coil assembly, or stator, is the stationary part of the electric motor that creates the magnetic field necessary for the armature to rotate. It is essential for the tool's operation.

Common signs include a strong burning smell, smoke coming from the motor vents, the tool tripping circuit breakers, or the motor humming but not rotating. Excessive sparking around the brushes can also indicate a field coil issue.

Yes, the 48L377 is a genuine OEM (Original Equipment Manufacturer) part from Walter Surface Technologies, ensuring exact fit and specification compliance.

Installation requires disassembling the power tool housing and handling electrical connections. It is recommended for individuals with experience in tool repair or qualified technicians to ensure safety and proper function.

No, this is the field coil assembly (stator) only. The armature (the spinning part) is a separate component. If your motor has failed, it is good practice to inspect both.

No, it is designed for specific models. Please check your tool's parts diagram or manual to confirm that part number 48L377 is listed for your specific machine.

OEM parts like this one are wound to the specific resistance and inductance required by the tool's design. Generic parts may not match these specs, leading to poor performance or damage to the switch and armature.

When replacing the field coil, you should also inspect the carbon brushes, the armature commutator, and the bearings. Replacing worn brushes at the same time is highly recommended.
