[0001] The present application relates to the motor technical field, specifically relates to a motor. BACKGROUND

[0002] With the improvement of people's living standards and consumption upgrading, the demand for personal care products such as electric toothbrushes, massage instruments, and face washing instruments is increasing, and people's requirements for user experience of such products are also increasing, which puts higher requirements on the motors of such products.

[0003] The existing motor mainly consists of a motor shell, an output shaft, a coil, a rotor assembly, a stator assembly, a permanent magnet, a motor cover, and a return spring.

Under the action of the magnetic field, the first magnetic pole assembly 531 and the second magnetic pole assembly 532 drive the rotor frame 51 to rotate, thereby driving the output shaft 3 to rotate.

The magnets in the magnetic pole assembly have identical structure, size, material, and magnetic field strength.

[0068] Specifically, the stator component 4 further includes:

[0069] A third iron core 433 is provided corresponding to the first magnetic pole assembly 531, and a fourth iron core 434 is provided corresponding to the second magnetic pole assembly 532; a third winding 453 is wound around the outside of the third iron core 433, and a fourth winding 454 is wound around the outside of the fourth iron core 434; the third winding 453 and the fourth winding 454 are connected in series.

[0070] The first iron core 431 and the second iron core 432 are arranged on the first side of the rotor member 5 along the axial direction of the output shaft 3; the third iron core 433 and the fourth iron core 434 are arranged on the second side of the rotor member 5 along the axial direction of the output shaft 3.

[0071] Preferably, as shown in Figure 2 , Figure 3 and Figure 8 , the side surfaces of the first iron core 431 and the second iron core 432 respectively pass through and are fixed to the inner walls of the first coil holder 421 and the second coil holder 422, and the core bosses 4311 of the first iron core 431 and the core bosses 4311 of the second iron core 432 pass through and are fixed in the two base plate notches 4113 on the first base plate 411, constituting the upper half of the entire stator member 4.

[0072] As shown in Figure 5 and Figure 11 , when the coils of the upper half of the stator member 4 are energized, a magnetic field is generated, the magnetic lines of force are concentrated in the iron core and flow through the iron core, the first iron core 431 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the first magnetic pole assembly 531, due to the opposite polarities of the first magnet 521 and the second magnet 522, according to the principle that like repels like and opposite attracts, the first iron core 431 simultaneously generates repulsion and attraction to the first magnetic pole assembly 531 of the rotor member 5, the generated repulsion and attraction have the same torque direction on the rotor member 5 (i.e. both clockwise or counterclockwise);

[0073] Similarly, the second iron core 432 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the second magnetic pole assembly 532, due to the opposite polarities of the first magnet 521 and the second magnet 522, according to the principle that like repels like and opposite attracts, the second iron core 432 simultaneously generates repulsion and attraction to the second magnetic pole assembly 532 on the rotor, the generated repulsion and attraction have the same torque direction on the rotor (i.e. both clockwise or counterclockwise), thereby increasing the torque of the output shaft;

[0074] Preferably, as shown in Figure 2 , Figure 3 and Figure 8 , the side surfaces of the third iron core 433 and the fourth iron core 434 respectively pass through and are fixed to the inner walls of the third coil holder 423 and the fourth coil holder 424, and the boss portions of the third iron core 433 and the fourth iron core 434 pass through and are fixed in the two base plate notches 4113 on the second base plate 412, constituting the lower half of the entire stator member 4.

[0075] Preferably, the upper half and the lower half of the stator member 4 are symmetrically distributed;

[0076] In combination Figure 5 and Figure 11 As shown in the figure, the coil of the lower half of the stator component 4 generates a magnetic field when energized, and the magnetic lines of force are concentrated in the core and flow through the core. The third core 433 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the first magnetic pole assembly 531. Due to the opposite polarities of the first magnet 521 and the second magnet 522, according to the principle of repelling same polarity and attracting opposite polarity, the third core 433 simultaneously generates repulsion and attraction on the first magnetic pole assembly 531 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor (i.e. both clockwise or counterclockwise);

[0077] Similarly, the fourth core 434 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the second magnetic pole assembly 532. Due to the opposite polarities of the first magnet 521 and the second magnet 522, according to the principle of repelling same polarity and attracting opposite polarity, the fourth core 434 simultaneously generates repulsion and attraction on the second magnetic pole assembly 532 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor (i.e. both clockwise or counterclockwise), thereby increasing the torque of the output shaft 3;

[0078] In summary, the four groups of cores and windings generate torque in the same direction on the magnetic pole assembly on the rotor through magnetic field interaction, thereby further increasing the torque of the output shaft.

[0079] Optionally, the core includes at least one of the first core 431, the second core 432, the third core 433, and the fourth core 434.

[0080] Optionally, the winding includes at least one of the first winding 451, the second winding 452, the third winding 453, and the fourth winding 454.

[0081] Specifically, the first winding 451, the second winding 452, the third winding 453, and the fourth winding 454 are connected in series; in the coil energized state, the magnetic field directions of the first core 431 and the third core 433 are the same, and the magnetic field directions of the second core 432 and the fourth core 434 are the same.

[0082] In this embodiment, in combination Figure 4 and Figure 10As shown, the first magnetic core 431 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the first magnetic pole assembly 531. Since the polarities of the first magnet 521 and the second magnet 522 are opposite, according to the principle that same polarity repels and opposite polarity attracts, the first magnetic core 431 simultaneously generates repulsion and attraction to the first magnetic pole assembly 531 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor, thereby synthesizing the first torque L1.

[0083] The third magnetic core 433 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the first magnetic pole assembly 531. Since the polarities of the first magnet 521 and the second magnet 522 are opposite, according to the principle that same polarity repels and opposite polarity attracts, the third magnetic core 433 simultaneously generates repulsion and attraction to the first magnetic pole assembly 531 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor, thereby synthesizing the third torque L3.

[0084] In combination Figure 10 As shown, in the coil energized state, since the magnetic field directions of the first magnetic core 431 and the third magnetic core 433 are the same and the polarities of the first magnet 521 and the second magnet 522 are opposite, the directions of the synthesized first torque L1 and the third torque L3 are consistent.

[0085] Similarly, in the coil energized state, since the magnetic field directions of the second magnetic core 432 and the fourth magnetic core 434 are the same and the polarities of the third magnet 523 and the fourth magnet 524 are opposite, the directions of the synthesized second torque L2 and the fourth torque L4 are consistent.

[0086] And the directions of the first torque L1 and the third torque L3 are consistent with the directions of the second torque L2 and the fourth torque L4, thereby synthesizing the rotor torque L, and further increasing the output torque of the output shaft.

[0087] Specifically, at least one of the first magnetic core 431, the second magnetic core 432, the third magnetic core 433, and the fourth magnetic core 434 is provided with a magnetic core groove 4312, which is arranged at one end of the magnetic core close to the magnetic pole assembly, and the magnetic core groove 4312 separates the magnetic core into a first magnetic attraction end 4313 and a second magnetic attraction end 4314.

[0088] In the coil unenergized state, the first magnetic attraction end 4313 and the second magnetic attraction end 4314 are adapted to be correspondingly attracted and connected with two magnets with opposite polarities, respectively.

[0089] Specifically, the magnetic core groove 4312 is symmetrically distributed with the axis L3 as the axis of symmetry.

[0090] Preferably, the stator member 4 is divided into two magnetic attraction ends by setting a groove in the middle of one end of the core with the axis L3 as the symmetry axis, after the coil is powered off, the magnetic pole assembly acts on the two magnetic attraction ends on the core through the magnetic field, the force of the two magnets of the magnetic pole assembly on the two magnetic attraction ends of the core is equal in size and opposite in direction, which can make the rotor drive the oscillating shaft to return to the initial equilibrium position without the need for resetting by the reset spring, while increasing the torque of the oscillating shaft, the torque consumption in the oscillating process of the oscillating shaft is reduced.

[0091] Specifically, the rotor member 5 includes a rotor frame 51, the rotor frame 51 is divided into two parts along the length direction with the symmetry axis L1 as the boundary line, the first magnetic pole assembly 531 and the second magnetic pole assembly 532 are symmetrically arranged at the two ends of the symmetry axis L1;

[0096] In this embodiment, the stator member 4 and the rotor member 5 have very high symmetry in the internal space of the motor, so that the amplitude of the mechanical vibration generated is within the normal working allowable range.

[0097] As a variation, at least one set of rotor members 5 is added on the axis of the output shaft 3, thereby forming at least two sets of rotor members 5 on the axis of the output shaft 3, and corresponding at least six cores and corresponding windings are arranged, the at least two sets of rotor members drive the output shaft 3 to oscillate under the action of the magnetic field, thereby increasing the torque of the output shaft.

[0098] Specifically, the iron core is spaced apart from the first magnetic pole assembly 531 or the second magnetic pole assembly 532.

[0099] Preferably, the iron core is spaced apart from the first magnetic pole assembly 531 or the second magnetic pole assembly 532, and after the coil is powered off, the magnetic field between the two magnetic attraction ends on the iron core and the magnetic pole assembly is non-contacting, the force of the two magnetic attraction ends on the iron core on the two magnets of the magnetic pole assembly is equal in size and opposite in direction, which can make the rotor drive the oscillating shaft to return to the initial equilibrium position, reducing the wear between components and prolonging the service life of the motor.

[0109] The working principle of the motor provided by the embodiment of the application is as follows:

[0110] Under the condition that the coil is electrified, the first iron core 431 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the first magnetic pole assembly 531, and because the polarities of the first magnet 521 and the second magnet 522 are opposite, according to the principle that the same polarity repels and the different polarity attracts, the first iron core 431 simultaneously generates repulsion and attraction to the first magnetic pole assembly 531 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor, thereby synthesizing a first torque L1.

[0111] The second iron core 432 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the second magnetic pole assembly 532, and because the polarities of the first magnet 521 and the second magnet 522 are opposite, according to the principle that the same polarity repels and the different polarity attracts, the second iron core 432 simultaneously generates repulsion and attraction to the second magnetic pole assembly 532 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor, thereby synthesizing a second torque L2.

[0112] The first torque L1 and the second torque L2 are superimposed in the same direction, thereby increasing the torque of the output shaft 3.

[0113] The third iron core 433 interacts with the magnetic fields of the first magnet 521 and the second magnet 522 of the first magnetic pole assembly 531, and because the polarities of the first magnet 521 and the second magnet 522 are opposite, according to the principle that the same polarity repels and the different polarity attracts, the third iron core 433 simultaneously generates repulsion and attraction to the first magnetic pole assembly 531 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor, thereby synthesizing a third torque L3.

[0114] The fourth iron core 434 interacts with the magnetic field of the first magnet 521 and the second magnet 522 of the second magnetic pole assembly 532. Due to the opposite polarities of the first magnet 521 and the second magnet 522, according to the principle of repelling between same poles and attracting between different poles, the fourth iron core 434 simultaneously generates repulsion and attraction to the second magnetic pole assembly 532 on the rotor, and the generated repulsion and attraction have the same torque direction on the rotor, thereby generating a third torque L4;

[0115] The third torque L3 and the fourth torque L4 are superimposed in the same direction, thereby increasing the torque of the output shaft 3;

[0116] The first torque L1, the second torque L2, the third torque L3 and the fourth torque L4 are superimposed in the same direction, thereby further increasing the torque of the output shaft 3.

[0117] At least one of the first iron core 431, the second iron core 432, the third iron core 433 and the fourth iron core 434 is provided with an iron core groove 4312. The iron core groove 4312 is arranged at one end of the iron core close to the magnetic pole assembly, and the iron core groove 4312 divides the iron core into a first magnetic attraction end 4313 and a second magnetic attraction end 4314. After the coil is powered off, the magnetic pole assembly has equal and opposite forces on the two magnetic attraction ends of the iron core, so that the rotor drives the oscillating shaft to return to the initial equilibrium position.
