Abstract

PURPOSE:To easily perform connecting operations by minimizing a magnetic loss sith a space between a plane coil and a magnet made small by a method wherein a coil end inside the plane coil is connected to a lead for connecting a substrate within the inside of the plane coil. CONSTITUTION:A rotor 7 is composed of a rotating disc 8 formed of a magnetic material and a disc on which a magnet 9 facing to the rotating disc 8 is mounted, and the substrate 12 to which a plurality of the plane coils 11 are fixed so as to be situated in the space between the rotating disc 8 and the magnet 9, is installed in a case 5. Moreover, the substrate 12 is provided with a control circuit in which the plane coils 11 are excited according to a position of the magnet 9. Each plane coil 11 is fixed on the substrate surface facing toward the magnet 9, and the coil end 16 inside the plane coil 11 is connected to the lead wire for connecting the substrate 12 within the inside of the plane coil 11. In such a manner, all of the coil ends also are not permitted to pass through the side on which the plane coil 11 to the magnet 9, and the space formed between the magnet 9 and the plane coil 11 is possible to be reduced.
