In other embodiments, the stator 7 may surround more than half of the outer peripheral surface of the rotor 9 or completely surround the outer peripheral surface of the rotor 9, and the opening on one side of the stator 7 is smaller or is not provided with an opening, so that the stator 7 and the rotor 9 are not easily separated, and further the stator 7 and the rotor 9 are conveniently detached and installed at the same time, thereby reducing the processes of installing the rotor 9 and the stator 7 respectively, and facilitating improvement of the working efficiency.

Example nine:

in any of the above embodiments, as shown in fig. 8 and 9, the motor includes a stator 7, the stator 7 includes a stator core 71 and at least two stator windings 72, the stator core 71 has at least two stator teeth 73, and the at least two stator windings 72 are respectively disposed on the at least two stator teeth 73.

In another embodiment, the motor includes a plurality of stators 7, and the plurality of stators 7 are arranged in combination or dispersed outside the rotor 9. Each stator 7 includes a stator core 71 and at least one stator winding 72, the stator core 71 has at least one stator tooth 73 thereon, and the at least one stator winding 72 is disposed on the at least one stator tooth 73, respectively.

The number of stators 7 in the motor can be set according to the power requirement, the type and weight of the load, etc.

Example ten:

in any of the above embodiments, the end faces of the stator teeth close to the rotor 9 are all equidistant from the center of rotation of the rotor 9. Because the stator windings 72 are arranged on the stator teeth 73, the magnetic force generated by the magnetic field generated by the plurality of stator windings 72 to the rotor 9 is balanced, and the stability of the rotor 9 in the rotating process is improved.

In one embodiment, the number of the stator teeth 73 is two, and the stator windings 72 on the two stator teeth 73 are sequentially energized and have the same polarity; or the number of the stator teeth 73 is two, the stator windings 72 on the two stator teeth 73 are energized simultaneously and have different polarities, and the magnetic poles of the stator windings 72 on the two stator teeth 73 alternate.

In this embodiment, when two stator teeth 73 are provided in the stator 7, there are two schemes for driving the rotor 9, one of which is that the stator windings 72 on the two stator teeth 73 are sequentially energized, and the polarities generated when the two stator windings 72 are energized are the same, and the two stator windings 72 are sequentially energized, so that the two stator windings 72 sequentially generate the acting force on the rotor 9, thereby driving the rotor 9 to rotate continuously; the other is that the stator windings 72 on the two stator teeth 73 are simultaneously energized, the two stator windings 72 generate different polarities when energized, the magnetic force generated by the stator windings 72 acts on the rotor 9 to rotate the rotor 9, and the polarities of the two stator windings 72 are alternately changed in the process of controlling the rotor 9 to rotate by energizing, so that the two stator windings 72 sequentially generate magnetic forces with different polarities, that is, the two stator windings 72 sequentially generate acting forces on different magnetic poles on the rotor 9, thereby driving the rotor 9 to rotate continuously.

Specifically, two setting schemes of the stator winding 72 are selected according to actual conditions and working requirements, so that the flexibility of setting the stator 7 of the motor is further enhanced, and the applicability of the motor is improved.

Wherein, the first driving scheme takes the energization polarity of the stator winding 72 as an example of N: specifically, when the stator windings 72 on the two stator teeth 73 are sequentially energized and both of them are N-poles, the first stator winding 72 is first energized to generate an N-pole magnetic field, according to the principle that magnetic poles attract each other in opposite directions, the S-pole of the magnetic member 2 in the rotor 9 is attracted to the position of the first stator winding 72, the N-pole of the magnetic member 2 passes through the second stator winding 72, the second stator winding 72 is closer to the N-pole of the magnetic member 2 in the rotor 9, the first stator winding 72 is de-energized and the second stator winding 72 is energized simultaneously, the second stator winding 72 generates an N-pole magnetic field, according to the principle that magnetic poles repel each other in the same direction, the N-pole of the magnetic member 2 is pushed by the N-pole magnetic field generated by the second stator winding 72 to move continuously toward the first stator winding 72, at this time, the second stator winding 72 is powered off, the first stator winding 72 is powered on, so that the first stator winding 72 generates an N-pole magnetic field to push the N pole of the magnetic member 2 to move continuously, and the second stator winding 72 is powered on, so that the rotor 9 rotates continuously in a circulating manner.

Wherein, the second driving scheme is that the stator windings 72 on the two stator teeth 73 are energized simultaneously and have different polarities, and the magnetic poles of the stator windings 72 on the two stator teeth 73 are alternated. The following are specific illustrations: specifically, when the first power is applied, the first stator winding 72 generates an N-pole magnetic field, the second stator winding 72 generates an S-pole magnetic field, and the two stator windings 72 are simultaneously energized, the first stator winding 72 emits an N-pole magnetic field, according to the principle that the magnetic poles attract each other, the first stator winding 72 attracts the S-pole of the magnetic member 2 of the rotor 9, the second stator winding 72 attracts the N-pole of the magnetic member 2 of the rotor 9, a tangential force is formed on the rotor 9, at this time, the magnetic poles of the first stator winding 72 and the second stator winding 72 are switched, at this time, the first stator winding 72 generates an S-pole magnetic field, the second stator winding 72 generates an N-pole magnetic field, according to the principle that like poles repel each other, the first stator winding 72 and the second stator winding 72 respectively generate repulsive forces on the S-pole of the magnetic member 2 and the N-pole of the magnetic member 2, so that the rotor 9 continues to rotate, at this time, the magnetic poles of the first stator winding 72 and the second stator winding 72 are switched, and the rotor 9 is rotated continuously by this cycle. In any of the above embodiments, optionally, the number of the stator teeth 73 is greater than or equal to 3, and the polarity of the stator winding 72 on any two adjacent stator teeth 73 is different.

In another embodiment, the number of the stator teeth 73 is greater than or equal to 3, and the polarity of the stator winding 72 on any two adjacent stator teeth 73 is different.

In this embodiment, when the number of the stator teeth 73 is greater than or equal to 3, it is preferable that two adjacent stator windings 72 are energized together, and the polarities of the two adjacent windings are opposite, so that the rotor 9 is subjected to a tangential force to provide power for the rotation of the rotor 9.

Specifically, when the number of the stator teeth 73 is set to three, the first stator winding 72 and the second stator winding 72 are energized, the first stator winding 72 generates an N-pole magnetic field to attract the S-pole of the magnetic member 2 in the rotor 9, the second stator winding 72 generates an S-pole magnetic field to attract the N-pole of the magnetic member 2 in the rotor 9, a tangential acting force is formed on the rotor 9, then, the second stator winding 72 and the third stator winding 72 are energized, the second stator winding 72 generates an N-pole magnetic field to repel the N-pole of the magnetic member 2 in the rotor 9, the third stator winding 72 generates an S-pole magnetic field to repel the S-pole of the magnetic member 2 in the rotor 9, the rotor 9 continues to rotate, and the cycle is repeated, so that the rotor 9 continuously rotates.

In any of the above embodiments, optionally, the number of the stator windings 72 is 3N, and the number of the magnetic poles of the magnetic member 2 of the rotor 9 is 4M; wherein N is a positive integer and M is a positive integer.

In this embodiment, the number of stator windings 72 is limited, that is, the number of stator windings 72 is at least 3, and when a larger number of stator windings 72 is required, the number of stator windings 72 is set to be an integral multiple of 3. The number of magnetic poles of the magnetic member 2 of the rotor 9 is 4 at minimum, and when a larger number of magnetic poles are required, the number of magnetic poles of the magnetic member 2 of the rotor 9 needs to be set to be an integral multiple of 4. The output efficiency of the motor can be made higher by the definition of the number of stator windings 72 and the definition of the number of magnetic poles of the magnetic member 2.

Specifically, when the requirement for the smoothness of the operation of the motor is high, the number of the stator windings 72 can be set to 6 or 9 or more, so that the number of the magnetic poles in the motor is increased, and the operation of the motor is more smooth. And each stator winding 72 is provided on a stator tooth 73, the number of stator teeth 73 should be provided the same as the number of stator windings 72.
