Be convenient for carry out the dismouting to rotor 2, stator 4 surrounds rotor 2 annular lateral surface half at most, avoids rotor 2 embedding stator 4 and is difficult to take place with the condition of stator 4 separation, and stator 4 is located between rotor 2 and the stator support 3, further inject stator 4 and be difficult to produce the influence to rotor 2's dismouting, convenience when improving change rotor 2.

Specifically, the stator 4 has a mating surface that mates with the rotor 2, the mating surface being disposed opposite a portion of the outer peripheral surface of the rotor 2 so that the rotor 2 can be separated from the stator 4 in the radial direction or the axial direction thereof. The surface of the stator 4 corresponding to the end surface of the stator tooth 43 constitutes a mating surface of the stator 4.

Since the rotor 2 can be separated from the stator 4 in the radial direction or the axial direction thereof, when the motor is applied to the food processor 8, the rotor 2 can be mounted with the cup 81 and separated from the base 82 along with the cup 81, and the stator 4 is mounted on the base 82, that is, the base 82 does not need to be provided with an integral motor, the overall height of the base 82 can be reduced, and the height of the overall food processor 8 can be reduced. In addition, compare annular stator in the correlation technique, this application sets up stator 4 into non-confined structure for stator 4's weight becomes light, thereby is favorable to realizing the lightweight of whole product, and convenience of customers draws the use, and occupation space diminishes, is convenient for accomodate.

In one embodiment, as shown in fig. 5 and 6, the motor includes a stator 4, the stator 4 including: a stator core 41 having at least two stator teeth 43 thereon; and at least two stator windings 42 respectively disposed on the at least two stator teeth 43.

In another embodiment, the motor includes a plurality of stators 4, and the plurality of stators 4 are arranged in combination or dispersed outside the rotor 2. Each stator 4 includes a stator core 41 and at least one stator winding 42, the stator core 41 has at least one stator tooth 43 thereon, and the at least one stator winding 42 is respectively disposed on the at least one stator tooth 43.

The number of stators 4 in the motor can be set according to the power requirement, the type and weight of the load, etc.

Alternatively, the end faces of the stator teeth 43 close to the rotor 2 are all equidistant from the center of rotation of the rotor 2. Because the stator windings 42 are arranged on the stator teeth 43, the magnetic force generated by the magnetic field generated by the plurality of stator windings 42 to the rotor 2 is balanced, and the stability of the rotor 2 in the rotating process is improved.

Alternatively, the number of the stator teeth 43 is two, and the stator windings 42 on the two stator teeth 43 are sequentially electrified and have the same polarity; or the number of the stator teeth 43 is two, the stator windings 42 on the two stator teeth 43 are energized simultaneously and have different polarities, and the magnetic poles of the stator windings 42 on the two stator teeth 43 alternate.

Specifically, when two stator teeth 43 are provided in the stator 4, there are two schemes for driving the rotor 2, one of which is that the stator windings 42 on the two stator teeth 43 are sequentially energized, and the polarities generated when the two stator windings 42 are energized are the same, and the two stator windings 42 are sequentially energized, so that the two stator windings 42 sequentially generate the acting force on the rotor 2, thereby driving the rotor 2 to rotate continuously; the other is that the stator windings 42 on the two stator teeth 43 are simultaneously energized, and the two stator windings 42 generate different polarities when energized, the magnetic force generated by the stator windings 42 acts on the rotor 2 to rotate the rotor, and in the process of controlling the rotor 2 to rotate by energizing, the polarities of the two stator windings 42 are alternately changed, so that the two stator windings 42 sequentially generate magnetic forces with different polarities, that is, the two stator windings 42 sequentially generate acting forces on different magnetic poles on the rotor 2, thereby driving the rotor 2 to rotate continuously.

Two arrangement schemes of the stator winding 42 are selected according to actual conditions and working requirements, so that the flexibility of arrangement of the stator 4 of the motor is further enhanced, and the applicability of the motor is improved.

Wherein, the first driving scheme takes the conducting polarity of the stator winding as N as an example: specifically, when the stator windings 42 on the two stator teeth 43 are sequentially energized and both of them have N poles, the first stator winding 42 is first energized to generate an N-pole magnetic field, according to the principle that the magnetic poles attract each other in opposite directions, the S pole of the magnetic member 23 in the rotor 2 is attracted, when the S pole of the magnetic member 23 in the rotor 2 is attracted to the position of the first stator winding 42, the N pole of the magnetic member 23 passes through the second stator winding 42, the second stator winding 42 is closer to the N pole of the magnetic member 23 in the rotor 2, the first stator winding 42 is de-energized, the second stator winding 42 is energized simultaneously, the second stator winding 42 generates an N-pole magnetic field, according to the principle that like poles repel each other, the N-pole magnetic field generated by the second stator winding 42 pushes the N pole of the magnetic member 23 to move continuously in the direction of the first stator winding 42, at this time, the second stator winding 42 is de-energized, the first stator winding 42 is energized, so that the first stator winding 42 generates an N-pole magnetic field to push the N pole of the magnetic member 23 to move continuously, and the second stator winding 42 is energized, so that the rotor 2 rotates continuously in this cycle.

Wherein, the second driving scheme is that the stator windings 42 on the two stator teeth 43 are energized simultaneously and have different polarities, and the magnetic poles of the stator windings 42 on the two stator teeth 43 are alternated. The following are specific illustrations: specifically, when the first power is applied, the first stator winding 42 generates an N-pole magnetic field, the second stator winding 42 generates an S-pole magnetic field, and the two stator windings 42 are simultaneously applied with power, the first stator winding 42 emits an N-pole magnetic field, according to the principle that the magnetic poles attract each other, the first stator winding 42 attracts the S-pole of the magnetic member 23 of the rotor 2, the second stator winding 42 attracts the N-pole of the magnetic member 23 of the rotor 2, a tangential acting force is formed on the rotor 2, at this time, the magnetic poles of the first stator winding 42 and the second stator winding 42 are switched, at this time, the first stator winding 42 generates an S-pole magnetic field, the second stator winding 42 generates an N-pole magnetic field, according to the principle that like poles repel each other, the first stator winding 42 and the second stator winding 42 respectively generate repulsive forces on the S-pole of the magnetic member 23 and the N-pole of the magnetic member 23, so that the rotor 2 continues to rotate, at this time, the magnetic poles of the first stator winding 42 and the second stator winding 42 are switched, and the rotor 2 is rotated continuously by the cycle.

Alternatively, the number of the stator teeth 43 is equal to or greater than 3, and the polarity of the stator winding 42 on any two adjacent stator teeth 43 is different. When the number of the stator teeth 43 is greater than or equal to 3, preferably, two adjacent stator windings 42 are energized together, and the polarities of the two adjacent windings are opposite, so that the rotor 2 is subjected to a tangential force to provide power for the rotation of the rotor 2.

Specifically, as shown in fig. 4 and 5, when the number of the stator teeth 43 is set to three, the first stator winding 42 and the second stator winding 42 are energized, the first stator winding 42 generates an N-pole magnetic field to attract the S-pole of the magnetic member 23 in the rotor 2, the second stator winding 42 generates an S-pole magnetic field to attract the N-pole of the magnetic member 23 in the rotor 2, and a tangential force is applied to the rotor 2, and then the second stator winding 42 and the third stator winding 42 are energized, the second stator winding 42 generates an N-pole magnetic field to repel the N-pole of the magnetic member 23 in the rotor 2, and the third stator winding 42 generates an S-pole magnetic field to repel the S-pole of the magnetic member 23 in the rotor 2, so that the rotor 2 continues to rotate, and the rotor 2 rotates continuously.

Alternatively, the number of the stator windings 42 is 3N, and the number of the magnetic poles of the magnetic member 23 of the rotor 2 is 4M; wherein N is a positive integer and M is a positive integer.

In this embodiment, the number of the stator windings 42 is limited, that is, the number of the stator windings 42 is at least 3, and when a larger number of the stator windings 42 is required, the number of the stator windings 42 is set to be an integral multiple of 3. The number of the magnetic poles of the magnetic member 23 of the rotor 2 is 4 at least, and when the number of the magnetic poles is more, the number of the magnetic poles of the magnetic member 23 of the rotor 2 needs to be set to be integral multiple of 4, and the output efficiency of the motor can be higher through the limitation of the number of the stator windings 42 and the limitation of the number of the magnetic poles of the magnetic member 23.

Specifically, when the requirement for the smoothness of the operation of the motor is high, the number of the stator windings 42 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 42 is provided on the stator teeth 43, the number of stator teeth 43 should be set the same as the number of stator windings 42.

In another embodiment, the stator 4 completely surrounds the annular outer side of the rotor 2, the rotor 2 being able to be moved away from the motor support together with the stator 4. Stator 4 surrounds rotor 2's cyclic annular lateral surface completely for separation is difficult for appearing in stator 4 and rotor 2, thereby is convenient for with rotor 2 and stator 4 dismouting in motor support simultaneously, improves the change efficiency to rotor 2 and stator 4.

In this embodiment, pivot 211 sets up on support body 11 through bearing 212, support body 11 provides the support for pivot 211, improves the stability of pivot 211, and bearing 212 can conveniently be dismantled and assembled in installing port 111 to be convenient for dismantle rotor 2 in support body 11, change rotor 2's convenience, pivot 211 can pass and dodge mouthful 121, and then make pivot 211 can be connected with external component, and rotor 2 drives external component through pivot 211 and rotates.
