POLYPHASE ARMATURE WINDING

PURPOSE:To uniformalize the quantity of the magnetic flux of each tee among slots, and to decrease vibration and noises by arranging coils having different phase to the mutual adjacent slots when the concentrically wound coils are inserted into the slots. CONSTITUTION:When the polyphase armature winding consisting of a plurality of the concentrically wound coils is inserted into a slot, the coil of one phase is disposed to the slot adjoining to the slot to which the coil of another phase is arranged. When the three phase four pole 36 slots, the coil of one pole is diposed crossing the slots 2, 7 in U phase, the coil of the next one pole is arranged crossing the slots 9, 18 and 11, 16, and the slots are connected in series. The coils of other two poles and V phase and W phase are disposed through the same method.
