ABSTRACT:
A multilayer aligned-winding coil (1) of a wide width wire, each layer having an obliquely crossing winding part extending obliquely with respect to a cross-section in one partial angular region of a virtual endless ring defined by the cross-section, and a transverse winding part extending transversely in an other partial angular region, includes a plural pairs of consecutive two layers meeting conditions 1 and 2; 1: a first row of winding portion including a transverse winding part having a progressively riding transverse winding part (YM, YM) riding progressively on a last row of the obliquely crossing winding part of a lower layer of the two layers to reach an upper layer thereover, and 2: a second row of winding portion including a riding and obliquely crossing winding part (RM, RM) having a ride-over region (X2, X4) crossing obliquely from a riding start region of the progressively riding transverse winding part (YM, YM) across a progressive riding region of the progressively riding transverse winding part (YM, YM). At least two pairs of the two layers have the ride-over region parts (X2,X4) at different angular regions (P1, P3) to provide the multilayer aligned-winding coil in which the wide width wire can be wound in multilayer and in alignment stably and at high space factor.
