PURPOSE:To minimize potential difference between each of the circuits connected and reduce cross currents by a mechanism wherein the number of slots per pole per phase is equalized with the number of parallel circuits, and the number of poles is divided by the number of the parallel circuits and excessive remainder turns are equally divided to the number of the parallel circuits. CONSTITUTION:The number of slots per pole per phase is equalized with the number of parallel circuits, and each parallel circuit is parted into remainder turns which the number of poles is divided by the number of the parallel circuits and remains and the fundamental turn except the remainder turns. The different phase of each phase belt is distributed to each parallel circuit equally in the fundamental turn, the remainder turns are equalized to the number of the parallel circuits and connected to ensure that the phase of the sum of the vectors of each half-turn coil in the phase belts agrees in each parallel circuit, and these remainder turns are connected in series with the fundamental turn. Thus, potential difference between each of the circuits connected is minimized and cross currents are reduced, and loss is decreased while the degree of freedom of design can be expanded. |
