A motor stator includes a silicon steel seat wound with six sets of starting coils and six sets of operating coils formed with resistant enameled coils. The six sets of starting coils are respectively made of the resistant enameled coils in directions respectively of entering into a first slot and out a fifth slot of the silicon steel seat, entering into a second slot and out a sixth slot, entering into a third slot and out a seventh slot, entering into an eleventh slot and out a seventh slot, entering into a twelfth slot and out an eighth slot, and entering into a first slot and out a ninth slot. And the six sets of operating coils are respectively composed of the resistant enameled coils in directions respectively different from the winding directions of the six sets of starting coils, able to quickly and evenly complete winding work.
