发明名称 ARMATURE WINDING FOR ROTARY ELECTRIC MACHINE
摘要 PURPOSE:To enable an insulating process with the insulating tube of a crossover, to be omitted, by permitting an interphase insulation to cross over one wire of the crossovers, at a section between two adjacent coils on the same circumference, and by connecting the wire to another crossover. CONSTITUTION:The crossover Wl of a coil W4 is connected to another crossover via a section between the coil W4 and a coil W3. The crossover Vl of a coil V4 is crossed over the interphase insulation Ip of V phase/W phase at the section between the coils W4, W3, and is connected to another crossover. The crossover Ul of a coil U4 is insulated and reinforced by an insulating tube Tu, and the interphase insulation Ip of U phase/V phase and V phase/W phase is crossed at the section between the coils W4, W3 and is connected to another crossover. Then, a coil interphase connecting section, from the section between the coils W4, W3 of the crossovers Ul, Vl, Wl, to a neutral point connecting section N is coated with insulation coating In by means of the insulating tube Tu, and the coating is set on the coil W3.
