Abstract
Described herein is a system and method to enable a wireless power transmission link system. The wireless power transmission link system may comprise a rotatable 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 wrapped coil. The wireless power transmission link system may comprise a second cup located interior to the telemetry unit and/or axle separated by an air gap from the first cup. The second cup may comprise a second channel for housing a second wrapped coil. The first wrapped coil and the second wrapped coil may be inductively coupled. The first cup and/or the second cup may comprise ferromagnetic material properties.
