<p>The apparatus comprises two members that are placed adjacent and opposing one another, and on the opposing surface of which a number of electrical paths are provided. The closed electrical paths do not enclose the rotational axis. At least one of the loops is energised with a carrier high frequency oscillating signal to create a flux that threads the loop on the opposing member. Modulation of the carrier frequency allows signals to be transmitted between the members. By using smaller current loops to increase the magnetic flux density, a data or control signal can be transmitted more efficiently between a turbine drive shaft and a stationary part of the turbine, such as nacelle gearbox.</p> |
