<p>PURPOSE: To transfer signals at a signal level and a power level by providing an annular stator where primary and secondary coils are wound around the adjacent leg parts on an U-shaped section and a rotor ferromagnetic member by performing combination in the axial direction of the U-shaped section. CONSTITUTION: An annular ferromagnetic stator 102 whose cross section is in U shape is provided. An annular ferromagnetic rotor 104 with a U-shaped cross section is arranged coaxially with the stator 102, and its leg part is combined with that of the stator 102. An outer leg part 106 of the rotor 104 is arranged close to an outer leg part 108 of the stator 102, and an inner leg part 110 of the rotor 104 is close to the inner periphery of the inner leg part 112 of the stator 102. A primary coil 114 is wound around the inner leg part 108 of the stator 102, and the secondary coil 116 is wound around the inner- periphery surface of the outer leg part 106 of the rotor 104, thus transferring signals at a signal level and a power level.</p> |
