Description
Technical Field
The invention relates to the technical field of miniature motors, in particular to a miniature motor capable of rotating in a reciprocating manner.
Background
The traditional iron core direct current vibration micro motor has wide application in vibration products such as face massager, health care equipment, personal care and the like. The traditional iron core direct current vibration motor drives the product to vibrate through the integral vibration of the iron core direct current vibration motor, has limited vibration amplitude and short service life, has the trend of being replaced by a reciprocating type rotating device in the application of some massage equipment, and the reciprocating type rotating device has the advantages of large swing, stable rotation beat, high reliability, long service life and the like. Along with popularization of application of the reciprocating rotating device, people correspondingly put forward higher requirements on the reciprocating rotating device, such as driving a larger brush head, and larger reciprocating rotating amplitude under the same beat.
Therefore, it is necessary to develop a miniature reciprocating motor which can rotate reciprocally, has a more compact structure, a larger torsion, a higher rotation beat and a larger reciprocating rotation amplitude.
Disclosure of Invention
In order to solve the technical problems, the invention provides a miniature motor capable of rotating in a reciprocating manner.
The technical proposal is as follows: the utility model provides a miniature reciprocating rotation's motor, includes casing, locates stator and the rotor in this casing, its key lies in:
The stator comprises a cylindrical stator core, N stator teeth are uniformly arranged on the inner wall of the stator core, coil windings are wound on the stator teeth, and magnetic poles generated by the coil windings on adjacent stator teeth are opposite;
The rotating shaft of the rotor is inserted at the axis of the stator core, N rotor teeth with magnetism are uniformly arranged on the rotating shaft along the circumferential direction of the rotating shaft, the magnetic poles of the adjacent rotor teeth are opposite, and the tooth tops of the rotor teeth face to gaps between the adjacent stator teeth respectively;
the rotor teeth are arranged on the stator teeth, and the rotor teeth are arranged on the stator teeth.
After the coil windings are electrified by adopting the technical scheme, the magnetic poles of the magnetic fields generated by the adjacent coil windings are opposite, namely, the magnetic poles on the adjacent stator teeth are opposite, and the magnetic poles on the rotor teeth are necessarily the same as the magnetic poles of one of the two adjacent stator teeth and are opposite, so that the rotor teeth can be necessarily caused to rotate towards the stator teeth attracted by the rotor teeth due to the repulsion and the opposite attraction of the same poles, when the current direction is changed, the direction of the magnetic field generated on the stator teeth is changed, the rotor teeth reversely rotate, the current direction is repeatedly changed, and therefore, the reciprocating rotation of the rotating shaft is realized, and in addition, the relative rotation angle between the stator and the rotor is limited through the rotation limiting mechanism, so that the rotor is effectively prevented from being twisted by external force when the stator is not electrified.
As a further preferred option:
the rotation limiting mechanism comprises limiting blocks and limiting clamping blocks, wherein two limiting blocks are respectively arranged on each stator tooth, one limiting clamping block is respectively arranged on each corresponding stator tooth on the rotating shaft, and the limiting clamping blocks rotate between the two corresponding limiting blocks on the corresponding stator teeth along with the rotation of the rotating shaft. When the limit clamping block rotates to one limit stop along with the rotating shaft, the limit clamping block is blocked by the limit stop and cannot continue to rotate, after the current direction is changed, the rotation of the limit clamping block is limited again when the limit clamping block rotates to the other limit stop, and therefore the control of the rotating angle of the rotating shaft is achieved.
The stator teeth are composed of tooth root parts and tooth top parts, wherein the tooth root parts are fixed on the inner wall of the stator iron core, the tooth top parts are of a C-shaped structure composed of two salient poles, limit stops are respectively arranged on the two salient poles, and the tooth top surfaces of the rotor teeth face to gaps between adjacent salient poles of the adjacent stator teeth. The rotor teeth with the structure are not separated from the corresponding two stator teeth all the time in the rotation process, when the rotor teeth are not electrified, if the rotor teeth are twisted by a certain angle by external force, attractive force exists between the magnetic field on the rotor teeth and the corresponding two stator teeth all the time, so that the rotor teeth are ensured not to be twisted in a transition way.
The rotating limiting mechanism further comprises two annular end pieces, wherein one end piece is respectively arranged at each of two cylinder openings of the stator core, N limiting parts with the same shape as the stator teeth are uniformly arranged on the inner ring of the end piece, the coil winding is wound on the tooth root parts of the stator teeth and the root parts of the limiting parts at the two ends of the stator teeth, one limiting stop block is respectively arranged on the outer side faces of the two free ends of the limiting parts, one limiting stop piece is fixedly arranged on the rotating shaft at the position corresponding to the end piece, one limiting clamping block is respectively arranged on each limiting part corresponding to the limiting stop piece, the limiting clamping blocks extend out along the radial direction of the rotating shaft, and the limiting clamping blocks rotate between the two limiting stops on the corresponding limiting parts. The rotor teeth with the structure can deflect at a certain angle relative to the stator teeth and can not rotate to a position opposite to one of the stator teeth all the time, so that under the condition of no power on, certain attractive force exists between the rotor teeth and the adjacent extending ends of the two adjacent stator teeth all the time, and the rotor teeth always stay between the two stator teeth.
And a reluctance groove is excavated in the middle of the top surface of the tooth top, and the notch of the reluctance groove is opposite to the axial lead of the rotating shaft. By adopting the design, the magnetic field intensity on the rotor teeth can be greatly reduced by the reluctance grooves, so that the attractive force between the rotor teeth and the stator teeth at the positions of the reluctance grooves is reduced, and in the unpowered state, the rotor teeth can return to the middle position between the rotor teeth and the adjacent two stator teeth under the balance of attractive force, and the position is the initial position.
The rotary shaft is sleeved with a cylindrical rotor core, N strip-shaped tooth grooves are formed in the rotor core, all the tooth grooves are uniformly distributed around the rotary shaft, and each tooth groove is provided with one rotor tooth respectively. The design is convenient for installing a plurality of rotor teeth on the rotating shaft.
The cross section of the rotor teeth is tile-shaped, and the circle center line of the rotor teeth and the circle center line of the top of the rotor teeth are coincident with the axis of the rotating shaft. When the scheme is adopted, the top of the rotor teeth and the top of the stator teeth are matched with each other, the gap between the rotor teeth and the top of the stator teeth is very small, the magnetic resistance between the gaps is also very small, and the rotating torque is increased during rotation.
Two insulating short sleeves are inserted in gaps between adjacent stator teeth respectively, the inner ends of the two insulating short sleeves are in butt joint, the outer walls of the insulating short sleeves are attached to the surfaces of the stator teeth, and the outer ends of the two insulating short sleeves are connected with the corresponding end pieces respectively. The insulating isolation sleeve with the structure is tightly attached to the tooth surface of the stator tooth, and compared with the process of brushing an insulating layer, the insulating isolation sleeve with the structure has the advantages of better insulating effect, more wear resistance and higher safety coefficient.
The shell is of a cylindrical structure with a small opening at one end and a large opening at the other end, the large opening end of the shell is buckled with an end cover, the outer end of the rotating shaft extends out of the small opening end of the shell through a first bearing, and the inner end of the rotating shaft is arranged on the end cover through a second bearing;
the rotor core and the rotating shaft between the second bearings are sleeved with adjusting springs, two ends of each adjusting spring are respectively abutted to the second bearings and the rotor core, each limiting baffle is annular and sleeved outside the corresponding adjusting spring, and each limiting baffle is fixedly connected with the corresponding rotor core. By adopting the scheme, the play of the bearing can be eliminated through the spring, and the noise in the using process is reduced.
And a sleeve is arranged on the rotating shaft between the rotor core and the first bearing, and two ends of the sleeve are respectively abutted against the rotor core and the first bearing. The axial position of the rotating shaft can be adjusted by the pipe sleeve by adopting the structure
The beneficial effects are that: compared with the traditional motor which is vibrated by the eccentric block, the motor provided by the invention has the advantages of more compact structure, large working swing, low noise, long service life, good stability, smaller moment of inertia and larger torsion, and the motor can accurately return to the original positioning origin after power failure.
