The sewing machine motor also comprises a first part 6 which is used for fixing a non-hand wheel 8 on the sewing machine main shaft 3, and a magnetic steel 7 is fixed on the first part 6.
In one scheme of the first component 6 fixing mode, the first component 6 is fixed on the end part of the rotor 2 through screws, so that the end part of the rotor 2 needs to be thick, and the material of the rotor is wasted. Therefore, in this embodiment, the manufacturing cost of the rotor 2 can be reduced as soon as the component is directly provided on the main shaft 3. In addition, a structure for matching the shapes of the rotor 2 and the first component 6 is not needed to be arranged between the two, so that the structure is simpler.
As shown in FIG. 4, the first part 6 is substantially annular, is made of plastic or aluminum alloy, and is of a one-piece construction. The first component 6 comprises a first annular fixing part 61 and a second annular fixing part 62 which is positioned outside the first fixing part 61, the first fixing part 61 extends out of the side part of the second annular fixing part 62, and a through hole 63 which is perpendicular to the axis of the rotor 2 and is used for penetrating a screw is formed in the first fixing part 61. Threads can be arranged on the through hole 63, and a screw penetrates through the through hole 63 to abut against the main shaft 3, so that the first component 6 is fixed on the main shaft 3; alternatively, the first member 6 can be fixed to the main shaft 3 by providing a screw thread at a corresponding position of the main shaft 3 of the sewing machine and passing the screw through the through hole 63 and fixing the screw thread to the main shaft 3. After the first part 6 is fixed on the main shaft 3, the first part 6 is approximately annular, so that dust entering the rotor 2 can be reduced to a certain extent, and the dustproof effect of the motor in the operation process is ensured.
The second fixed part 62 is provided with a third annular fixed part 64, the magnetic steel 7 is fixed in the third fixed part 64, and the second fixed part 62 is provided with a counterweight part 65 at a position symmetrical to the third fixed part 64. The weight of the counterweight part 65 is approximately equal to the total weight of the fixing part three 64 and the magnetic steel 7, and the counterweight part 65 is arranged on the first component 6, so that when the motor operates, the first component 6 operates more stably and the balance is better. The third fixing portion 64 is annular, so that the magnetic steel 7 can be more stably fixed on the first component 6. The magnetic steel 7 is fixed on the first component 6 through glue. In addition, the fixing can also be realized through a common buckle structure, for example, a convex block is arranged on the magnetic steel 7, a groove is arranged on the first component 6, and the convex block on the magnetic steel 7 is embedded into the groove on the first component 6 during installation, so that the fixing effect is realized.

When the motor is assembled to the sewing machine, the positions of the stator 1 and the rotor 2 of the motor are determined, and because the Hall sensor 5 is fixed on the stator 1 in the structure of the motor of the sewing machine, the position of the Hall sensor 5 is determined when the motor is assembled to the sewing machine; in addition, in the motor, the magnetic steel 7 is independently fixed on the first part 6, and the first part 6 is fixed on the main shaft 3 of the sewing machine, so that the position of the magnetic steel 7 is also determined. Therefore, in the sewing machine motor, the position of the magnetic steel 7 is determined without being influenced by the installation position of the hand wheel 8, and the assembly efficiency is greatly improved.
