The Husqvarna 531073878 Field Coil 110V is a genuine OEM motor component designed for the DM225 and DM225D concrete core drills. As a direct Husqvarna replacement, this coil is wound and rated to the exact electrical specifications of the original, ensuring the drill motor performs the way it was built to. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- OEM-Spec Winding and Voltage Rating — Manufactured to Husqvarna's original 110V specification, delivering the correct electromagnetic output for consistent motor torque and speed control.
- Drop-In Motor Replacement — Engineered to the same dimensions and terminal configuration as the original, allowing straightforward installation in DM225 and DM225D drill motors without modification.
- Confirmed Fitment for DM225 and DM225D Core Drills — Cross-reference part number 531073878 against your parts diagram to verify compatibility with your specific concrete core drill model.
- Restores Full Motor Output — A correctly functioning field coil sustains the magnetic field that drives rotor rotation; replacing a failed coil brings the motor back to its rated power and prevents overheating caused by an open or shorted winding.
- Electrical Safety Compliance — Genuine OEM construction ensures the coil meets the original insulation class and dielectric ratings, supporting safe operation in demanding wet-core drilling environments.
The field coil is the stationary winding inside an electric motor that generates the magnetic field responsible for driving the rotor. In a core drill motor like those found in the DM225 and DM225D, the field coil must maintain a precise and consistent electromagnetic field to deliver stable torque through demanding concrete and masonry applications. When a field coil begins to fail — through insulation breakdown, a shorted turn, or an open winding — the motor loses power, runs hot, draws excessive current, or stops entirely. Replacing the field coil with a genuine OEM unit restores the motor to its original performance specification and protects downstream components from the stress caused by an underperforming winding.
