Abstract

PURPOSE:To contrive miniaturization, air gap enlargment, etc., by allowing the area ratio of the relative surfaces of an iron core to an ootimum value for the best characteristic within the restricted size of the iron core. CONSTITUTION:The first and second iron cores 11, 12 are arranged coaxially with two coaxial grooves formed respectively on rotary surfaces opposed each other, and coils 21-24 are loaded on each grooves. A pair of coils 21-24 opposed each other are electromagnetically coupled between the rotary and fixed sides. When the areas of surfaces formed on the both sides of grooves of the iron cores 11, 12 and opposed each other across a gap between the first and second iron cores 11, 12 are represented by A, B, C respectively from the inside, the area ratio B/A is set in a range 1-1.75 and one B/C in a range B/A+ or -0.25.
