<p>PURPOSE:To provide a rotary transformer where crosstalk can be prevented positively and degree of transformer connection can be improved without using a short-circuiting coil. CONSTITUTION:In a rotor part 1 and a stator part 2, end faces 1a and 2b of magnetic substrates 11 and 21 are provided opposingly on a rotary shaft 01 of the rotor part 1. In the rotor part 1, non-magnetic insulation parts 12 and 13 are laid out annularly around the rotary shaft O1 with a spacing G1 within the magnetic substrate 11 and coils 14 and 15 are buried inside the non-magnetic insulation parts 12 and 13. In the stator part 2, non-magnetic insulation parts 22 and 23 are laid out annularly around the rotary shaft O1 with a spacing G2 within the magnetic substrate 2 and coils 24 and 25 are buried inside the non-magnetic insulation parts 22 and 23. A recessed groove 26 is provided so that it is located within the spacing G2 of the coils 21 and 22 on the end face 2a of the magnetic substrate 21 at the opposite side of the end face 2b.</p> |
