1 channel and 2,000 channels ■Coil (chl) (C
R2)'&-groove fGl ... formed on a flat plate with +11 peaks,
A magnetic circuit is formed between both flat plates 111111 by facing each other as a rotor and the other as a stator, and the excitation magnetic flux from one coil induces an electric current in the other 17 coils. However, in both flat piles (1), the 1,000-channel and 2-channel channels are close to each other on the magnetic circuit.
When v-crosstalk occurs and a small signal M is required, this crosstalk is considered to be a major problem. In the case of Figure 9, the path of the solid line q) of the magnetic flux of the 1-handed Yannel coil (chi) is valid, and the path of the dotted line (ciI) disturbs the effective magnetic flux due to the 2-handed Yannel coil (CR2) and is invalid. h
In particular, the dotted line &-1 spanning part 0 of the 2-channel coil (CR2) corresponds to the crosst -/). The same can be said about the 2,000-yam coil (CR2) side. Even if the shape is made ten times larger, it is still difficult to suppress the crosstalk to a level lower than that of a flute. What has yet to be invented is a rotary transformer that eliminates the above-mentioned drawbacks, prevents crosstalk between both channels, is easy to install, and can be provided at low cost? It is something that is offered as a donation.

Therefore, the image portions (1a) and (Ib) can be provided as an integral +I-shaped object supported by the non-magnetic plate (3), and the dividing portion (2)
Crosstalk can be prevented by reducing the magnetic permeability between the two channel coils (chl) (CR2).

(5bM5c). The coil forming portions of the support portions are each cut out, and only the bottom portions are made of the same material and connected together. Practically speaking, it is desirable that the number of supports be 3 to 4. Although it is possible to use a combination in which the numbers of support parts are different for the rotor side and the stator side after cutting, two molds are required, which is uneconomical. In short, both channel coils (ch

This reduces the mutual magnetic permeability of both coils and reduces crosstalk. At the same time, it is possible to obtain a rotating transformer that is lightweight and inexpensive.

Therefore, since all of the opposing support parts on the rotor side and the stator side do not coincide at the same position, there is little change in magnetic permeability.
