- 摘要：
FIELD: electricity.SUBSTANCE: rotary transformer 5 includes plate-type stator 51 having coil placed at one its surface and plate-type rotor 52 having coil placed at one its surface, wherein the respective surfaces for coils placement are opposed so that signal in the range of 1-10 MHz is transferred between the coils. Stator includes substrate 512 with plurality of single coils are shaped on it as concentric circles and bearing element 513. Rotor includes substrate 522 with the same number of single coils 521 shaped on it as concentric circles and bearing element 523. Air and material M, which is an insulator and has relative magnetic permeability equal in essence to 1, is placed between substrate 512 and bearing element 513 and between substrate 522 and bearing element 523.EFFECT: ensured possibility of effective multichannel transfer of signal without increase of the device dimensions.4 cl, 16 dwg
