48H561 - Walter 110V Replacement Field Coil Stator

Technical Overview of the Walter 48H561 Field Coil

The Walter 48H561 is a precision-engineered field coil (stator) designed for specific 110V electric power tools manufactured by Walter Surface Technologies. As a critical component of the universal motor assembly, this field coil is responsible for generating the stationary magnetic field required for the armature to rotate. It is constructed with high-purity copper windings to minimize electrical resistance and maximize magnetic flux density, ensuring the tool operates at its rated efficiency.

Over time, field coils can degrade due to thermal cycling, vibration, or abrasive dust ingress, leading to short circuits or open windings. This OEM replacement part is built to meet the exact electrical and physical specifications of the original equipment, ensuring proper fitment within the motor housing and correct alignment with the armature. The insulation system is designed to withstand the high operating temperatures and mechanical stresses typical of industrial grinding and finishing applications.

Technicians replacing this component should verify the tool's voltage rating matches the 110V specification of this coil. Installation requires disassembly of the tool housing and proper connection of the field leads to the switch and brush holders. Using genuine Walter parts like the 48H561 ensures that the tool retains its safety certifications and performance characteristics.
