A high-power and high-torque step motor comprising a stator which is provided with a first stator pole, a second stator pole, a third stator pole, a fourth stator pole, a fifth stator pole, a sixth stator pole, a seventh stator pole and a eighth stator pole. An A-phase winding orderly winds around the first, third, fifth and seventh stator poles, and a B-phase winding orderly winds around the second, fourth, sixth and eighth stator poles. The first, second, fifth and sixth stator poles are wound in the same direction, and the winding direction of the third, fourth, seventh and eighth stator poles is opposite to that of the first, second, fifth and sixth stator poles. By such arrangements, the high-power and high-torque step motor is formed.
