Abstract
Abstract Windings for electrical inductive apparatus are disclosed which include a plurality of first and second pairs of disc coil sections arranged in a stack. Each of the second pairs of disc coil sections are disposed between the first pairs of disc coil sections. Each of the disc coil sections includes two conductors wound in parallel with each other. Each of the two conductors at the inner ends of each section in the first pair of disc coil sections are connected to each of the two conductors at the inner ends of each section in the second pair of disc coil sections, respectively. One conductor at the outer ends of the two sections in the second pair of disc coil sections is connected to one conductor at the outer ends of the two sections in the first pair of disc coil sections. Each of the three conductors at the outer end of two sections in the second pair of disc coil sections is connected to one of three conductors at the outer end of two sections in the next first pair of disc coil sections, respectively.
