<p>PURPOSE:To realize a superior small-sized rotary transformer causing an unbalance of a net inductance by a method wherein a winding groove, which is magnetically divided by a short ring, is constructed in such a manner that a groove depth thereof is deep at a division end part and shallow at a central part. CONSTITUTION:Four signal transmission systems (hereinafter called CH) are constructed. Let the respective signal transmission systems called CH1, CH2, CH3, and CH4 in the order from the top system. The combination inductance of the CH2 and CH3 is large, and that of the CH1 and CH4 is small. In addition, the coupling coefficients of the CH2 and CH3 is large, and that of the CH1 and CH4 is small. Since the larger the combination inductances are, the larger the net inductance is, and also the larger the coupling coefficients are, the smaller the net inductance is. Judging from the above-mentioned contents, two factors are generally offset with respect to each other and the net inductance of all the four CHS can coincide with each other.</p> |
