Abstract
Described herein is a system and method to enable a wireless power transmission link system. The wireless power transmission link system may comprise an axle and an optional telemetry unit interior to the axle. The wireless power transmission link system may comprise a first cup located interior to the telemetry unit and/or the axle. The first cup may comprise a first channel for housing a first wound coil. The wireless power transmission link system may comprise a second cup separated by an air gap from the first cup. The second cup may comprise a second channel for housing a second wound coil. The first wound coil and the second wound coil may form a portion of an inductively coupled, resonant, air-core transformer. The first cup and/or the second cup may comprise ferromagnetic material properties.
