<p>PURPOSE:To obtain a compact and rotary type transformer device which is suited for multiple channels by changing the groove width of inner diameter and that of outer diameter of a rotary member. CONSTITUTION:Inductance and connection coefficient become nearly the same value by making smaller a groove width W1 of a central rotary transformer 2 and by making larger a groove width W2 to constitute a rotary transformer without any difference in electromagnetic conversion characteristics. A shield plate 4 is provided at the center of a central rotary transformer 2 to prevent crosstalk at outside and inside of the central rotary transformer 2. It eliminates the difference in inductance at the inner and outer channels and the connection coefficient to be nearly the same value to obtain a compact and multi-channel rotary transformer device without any crosstalk.</p> |
