1. A stator of a stepping motor, comprising:
a first magnetic field closed loop comprising a first main body, a first main driving pole, and a first auxiliary driving pole, wherein the first main driving pole and the first auxiliary driving pole are spaced on the same side of the first body, the first main driving pole and the first auxiliary driving pole are configured to assemble a coil of the stepping motor; and a second magnetic field closed loop comprising a second main body, a second main driving pole, and a second auxiliary driving pole, wherein the second main driving pole and the second auxiliary driving pole are spaced on the same side of the second body, the second main driving pole and the second auxiliary driving pole are configured to assemble the coil of the stepping motor; wherein the first main driving pole is adjacent to the second main driving pole, and the first main driving pole and the second main driving pole are spaced, the first auxiliary driving pole and the second auxiliary driving pole are spaced; wherein the first main driving pole, the first auxiliary driving pole, the second main driving pole, and the second auxiliary driving pole cooperatively enclose to form a receiving hole for receiving a rotator of the stepping motor; and wherein an open space is formed between one end of the first body adjacent to the first auxiliary driving pole and one end of the second body adjacent to the second auxiliary driving pole and/or between one end of the first body adjacent to the first main driving pole and one end of the second body adjacent to the second main driving pole. |
