Abstract
PURPOSE:To obtain an armature coil with good workability and high yield by more widening the conductor pitch of a coil on the more outer peripheral side at the time of winding said coil round a cylinder. CONSTITUTION:Clockwise and counterclockwise unit coils 14 with the same phase in the obverse and reverse are paired to form a unit coil group 16, A printing coil 10 is wound round a cylinder in such manner that its left and right sides form the inner and outer peripheries respectively, to form an armature coil 30. Therefore, the length of said unit coil group 16 differs between the inner and outer peripheral sides so as to become longer more outwardly. Also, in order that conductors are axially arranged in each unit coil 14 at equal angles towards the circumferential direction, said unit coil groups 16 are constituted in the manner of overlapping with each other at the level of a conductor pattern. Accordingly, a gap between conductors of the unit coil group 16 positioned on the outer peripheral side of said cylinder is wider than that between conductors of said group 16 arranged on the inner peripheral side thereof. Such conductor pattern relaxes manufacturing conditions of said printing coil 10 and relatively improves the yield of an etching process.
