A laminated core for a rotating electric machine comprising a plurality of single sheet cores, each single-sheet core being formed by arranging a plurality of salient poles continuously on a beltlike yoke plate and winding the beltlike yoke plate so as to be cylindrical while joining both ends of the beltlike yoke plate, wherein the laminated core is cylindrical and has a plurality of salient poles confronting a magnet, each salient pole having a winding and the laminated core is formed by laminating a plurality of the single-sheet cores.

Laminated core of rotating electric machine

An object of this invention is to provide a circuit board low in manufacturing cost in which aimed circuit patterns having a circuit gap therebetween can be short-circuited substantially irrespective of the length of the circuit gap while being insulated from other circuit patterns which are laid in the circuit gap. In a circuit board on which a plurality of circuit patterns are arranged, a selected one of circuit patterns is cut to have a circuit gap where the selected circuit pattern is laid across the remaining circuit patterns, in such a manner that the circuit gap divides the selected circuit patterns into two parts, a conductor formed by cutting a wire to the length of the circuit gap bridges the circuit gap, to short-circuit the two parts thereby to complete the selected circuit pattern, the conductor being insulated from the remaining circuit patterns laid across the circuit gap.
