<p>PURPOSE:To obtain balance of inductance of a rotary transformer by a method wherein the areas of the mutually facing surfaces of the respective protruding parts between the adjoining circular grooves of a flat board type ferrite core, between the circular groove at the outermost periphery and the outermost periphery, and between the circular groove at the innermost periphery and the innermost periphery are made the same. CONSTITUTION:The coils 3, 5 of a rotor 1 act magnetically with the coils 4, 6 of a stator 2 through the surface of the rotor 1. The areas of the mutually facing surfaces of the respective protruding parts between the channel 1 (CH1) and the channel 2 (CH2) of the rotor 1 and the stator 2 thereof, between the CH1 and the inner periphery, and between the CH2 and the outer periphery are indicated by S5, S4, S6. The areas of the S5, S4, S6 thereof are made as to be the same area, and inductances between the respective CHs are balanced.</p> |
