<p>PURPOSE:To provide a rotary transformer in which the distributed capacitance is reduced significantly between the turns of coil while increasing the self resonance frequency and enlarging the frequency bandwidth. CONSTITUTION:The rotor section 1 and the stator section 2 comprise, respectively, base bodies 10, 20 and coils 11-17, 21-27. The base bodies 10, 20 have at least one faces 100, 200 opposing each other through a gap G. The coils 11-17, 21-27 are embedded closely to the opposing faces 100, 200 of the base bodies 10, 20 so that the coils rotate around a rotational axis. At least one of the rotor section 1 or the stator section 2 belongs to identical channel and includes predetermined number of turns of coils (11, 13, 14, 16, 17) and (21, 23, 24, 26, 27) and air gap grooves 41, 51, 52 provided between the turns of coils (11, 13, 14, 16, 17) and (21, 23, 24, 26, 27).</p> |
