Abstract
A rotor telemetry apparatus 60 for providing a data communication link between a rotating member 68 and a stationary member 66 of a rotary machine is disclosed. The rotor telemetry apparatus includes a pair of coils 72 each mounted on an associated member for transferring electrical energy between the stationary member 66 and rotating member 68 of the turbomachine. At least one coil of the pair of coils is held by a first layer 88 of bonding agent and is attached to one of the members by a second layer 90 of bonding agent which is filled with a magnetizable material having a magnetic permeability under operating conditions that is greater than the magnetic permeability of the bonding agent. A method of assembling the coils to the stationary and rotating members is also disclosed. In one embodiment a pair of cooperating antennas 70 are disposed between the cooperating coils and spaced by a portion of the first layer containing the coils away from the second layer of bonding agent filled with a magnetizable material.
