Rectangular Coil — educational diagram — Fig.: Diagrama educativo de “Rectangular Coil”.

Rectangular coils fill oblong pad openings common on narrow AGV paths and slot-shaped receiver bays. A racetrack (rounded rectangle) reduces sharp corner field crowding compared to a sharp-edged rectangle while still matching the vehicle geometry.

Inductance and field uniformity depend on aspect ratio. Long thin rectangles concentrate flux along the long edges; corners contribute less usefully to central coupling unless ferrite guides the path.

01Applications

Floor strips or narrow charging bays in warehouse aisles.
Receiver packs aligned with the vehicle frame rails.
Multi-pad lanes where several rectangular segments tile a lane.

02Design guidance

Use rounded corners or filleted traces on PCB coils to reduce high current density spots. Place ferrite tiles to close the flux path behind the straight sections first — corners are where leakage and mechanical stress concentrate. Measure k for offset along both long and short axes; rectangular coils are inherently anisotropic.

03Watchouts

Higher inter-turn capacitance on long outer legs can lower self-resonance.
Mechanical winding tension varies on straight vs curved sections — consistency affects L repeatability.
Asymmetric misalignment can excite different eddy-current patterns in nearby steel.
