Problems solved by technology

[0006] When the outer diameter of the stator is less than 20mm, the notch of the motor will be very small, which will cause difficulty in winding the motor; at the same time, because the winding is wound on the main pole of the motor, the space for the entry and exit of the winding nozzle will occupy the area of ​​the slot, affecting the motor. The slot full rate further affects the output torque of the motor

Embodiment 1

[0033] like image 3 As shown, the overall stator is divided into four pieces: stator block 11, stator block 12, stator block 13 and stator block 14. The four stators are the same, wherein stator block 11 and stator block 13 belong to phase A, and stator block 12 and stator block 14 Belonging to phase B, there are two stator teeth on each stator block, and the angle between the two stator teeth is 30°.

[0034] In the counterclockwise direction, the stator blocks are the stator block 11, the stator block 12, the stator block 13 and the stator block 14, and the angles between the stator blocks are 45°, 75°, 45°, and 75°.

[0035] The stator teeth on the stator block 11 are TA1 and TA2 in turn, the stator teeth on the stator block 13 are TA3 and TA4 in turn, the stator teeth on the stator block 12 are TB1 and TB2 in turn, and the stator teeth on the stator block 14 are TB3 and TA4 in turn. TB4.

Embodiment 2

[0040] like Figure 4 As shown, the overall stator is divided into stator block 21 and stator block 22. The two stator blocks are the same, wherein the stator block 21 is the A phase, and the stator block 22 is the B phase. There are 4 stator teeth on each stator block. The angles between the two ends of the two stator blocks are 15° and 45°.

[0041] In the counterclockwise direction, the stator teeth on the A-phase stator block 21 are TA1, TA2, TA3 and TA4 in turn, and the angles between the four stator teeth are 60°, 30°, and 60° in turn.

[0042] In the counterclockwise direction, the stator teeth on the B-phase stator block 22 are sequentially TB1, TB2, TB3 and TB4, and the angles between the four stator teeth are 60°, 30°, and 60°.

[0043] Compared with embodiment 1, embodiment 2 adds new yoke parts YA3 and YB3, which means that a new winding space is added, such as Figure 4 As shown, it is beneficial to increase the output torque of the motor.

Abstract

The invention relates to a 15-degree stepping angle stepping motor, and the motor comprises a winding, a rotor and a stator; the rotor is provided with six pairs of poles, the stator is of a split structure and comprises an even number of stator blocks with the same shape, and at least two stator teeth are distributed on each stator block; and a stator yoke part for winding a winding is formed between adjacent stator teeth in each stator block. Compared with the prior art, the winding machine has the advantages that modular winding production of the motor is facilitated, and the production efficiency of the motor is improved.

Description

technical field [0001] The invention relates to a stepping motor, in particular to a stepping motor with a step angle of 15°. Background technique [0002] The existing 15° two-phase stepping motor such as figure 1 , figure 2 As shown, 1A and 1B are the stators of Scheme 1 and Scheme 2 respectively, and 2 is the rotor of the existing scheme. The rotors can be formed by stacking punched sheets, or they can be permanent magnet rotors, but they are N and S alternately. 6 pairs of poles. [0003] In the existing scheme 1, the stator has 8 main poles, A-phase main poles A1, A2, A3, A4 and B-phase main poles B1, B2, B3, B4, each main pole has a stator tooth, a total of 8 Stator teeth TA1, TA2, TA3, TA4 and TB1, TB2, TB3, TB4. The 8 main poles are arranged in the counterclockwise direction as A1, B1, A2, B2, A3, B3, A4, B4, and the clips in between The angles are all 45°. [0004] In the existing scheme 2, the stator has 8 main poles, A-phase main poles A1, A2, A3, A4 and B-p...
