Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-3, the utility model discloses a motor element for manadesma rifle, include the outer rotor brushless motor who comprises rotor part 1, stator part 2 and control circuit board 3, stator part 2 includes integrated into one piece's stator support 21 and motor support 22, the fixed iron core winding 23 that is provided with in periphery of stator support 21, stator support 21 is connected with rotor part 1 rotation through bearing 24, be equipped with a plurality of mounting holes 221 that can install the manadesma rifle casing on the motor support 22.
As shown in fig. 4, in order to fix the external rotor motor in the fascial gun, a stator adapter 4 needs to be disposed on a stator of the motor, and then the stator adapter 4 is fixed on a motor mounting bracket 5, and the motor mounting bracket 5 is fixed on the fascial gun housing. In addition, the circuit board 6 is generally disposed between the stator adapter frame 4 and the rotor 7, and a certain gap needs to be left between the stator adapter frame 4, the circuit board 6 and the rotor 7, so that the whole motor assembly occupies a large space in the axial direction.
This application closes split type stator support, stator switching frame 4 and motor mounting bracket 5 in prior art as an organic whole, forms an overall structure to the space that motor element occupy has been dwindled greatly, is favorable to realizing the miniaturization of whole manadesma rifle casing.
To the concrete structure of the outer rotor brushless motor of this application, similar with traditional motor, promptly rotor part 1 includes shell 11, sets up magnet steel 12 on shell 11 inner wall to and with the coaxial fixed dabber 13 in shell 11 bottom, the center of stator support 21 is equipped with through-hole 211, wholly is tubular structure, dabber 13 passes through-hole 211 to rotate with stator support 21 through the bearing 24 in the through-hole 211 and be connected. The shell 11 and the magnetic steel 12, the stator support 21 and the iron core winding 23, and the core shaft 13, the through hole 211 and the bearing 24 can be bonded and fixed through the super glue, so that the processing and assembling difficulty is reduced.
In order to make the motor rotate stably, the two bearings 24 are respectively located in two ends of the through hole 211 of the stator bracket 21, wherein the inner end of the bearing 24 far away from the bottom of the housing 11 is provided with a wave-shaped elastic sheet 25, and the outer end is provided with a shaft retainer 26. The wave-shaped elastic sheet 25 is used for eliminating or reducing bearing vibration by applying prestress on the bearing 24, reducing bearing noise and improving the running precision and stability of the bearing. The shaft retainer ring 26 mainly limits the bearing 24, plays a role in axial fixation and prevents the working and running of the motor from loosening.
Further, the bearing 24 is a deep groove ball bearing, wherein the size of the bearing 24 far from the bottom of the housing 11 is larger than that of the bearing 24 near the bottom of the housing 11. Because the fascial gun is in use, the rotating shaft of the motor can bear the reverse acting force from the massage head, and the deep groove ball bearing can well bear the radial acting force. Meanwhile, the reaction force is first transmitted to the bearing 24 far from the bottom of the housing 11, and therefore, the type of the bearing 24 far from the bottom of the housing 11 is preferably larger than that of the bearing 24 near the bottom of the housing 11, so that the structural strength and the impact resistance are improved, and the service life of the whole motor is prolonged.
Furthermore, a graphite nylon gasket 27 is provided between the stator frame 21 and the bottom of the housing 11. Graphite nylon gasket 27 has wear-resisting resistant high low temperature antistatic characteristics, and the dress can prevent the wearing and tearing between stator part 2 and the rotor part 1, reduces the bearing noise, improves running accuracy and stationarity.
As for the motor bracket 22, since the motor bracket is required to bear the weight of the motor and also to leave an avoidance space for the reciprocating mechanism of the fascial gun, the motor bracket 22 is of a C-shaped, triangular or rectangular frame structure as a whole, the C-shaped frame can enable the reciprocating mechanism to pass through the gap, and the triangular or rectangular shape enables the reciprocating mechanism to pass through the middle cavity of the motor bracket. The stator support 21 is located on the side of one edge of the motor support 22, the axis of the through hole 211 is parallel to the frame plane of the motor support 22, the mounting hole 221 is located on the periphery of the motor support 22, and the axis of the mounting hole is perpendicular to the frame plane of the motor support 22. This structure can make motor support 22 better bear motor weight, guarantees the stability of motor motion.
In order to reduce vibration and noise generated when the motor operates, a damping ring 222 is fitted into the mounting hole 221. During installation, the screws penetrate through the damping rings 222 and then are fixed on the fascia gun shell, so that the vibration transmitted to the fascia gun shell by the motor during operation is reduced, and the holding comfort is improved.
The control circuit board 3 is an indispensable component of the external rotor brushless motor, and the existing external rotor brushless motor mainly has two forms, one is a sensing brushless motor, namely, a magnetic pole is sensed by a hall sensor on the circuit board, so that the control circuit switches current, therefore, if the sensing circuit board is adopted, the control circuit board 3 must be fixed at any end of the stator support 21 so as to sense the change of the magnetic pole, and is usually arranged at the outer end of the stator support 21 for convenient maintenance; the other is a non-inductive brushless motor, namely, a counter electromotive force method, an inductance method, a flux linkage method, a high-frequency pulse method and other intelligent methods are adopted to judge the magnetic poles, and the counter electromotive force method is most applied, so that if a non-inductive circuit board is adopted, the non-inductive circuit board does not need to be arranged near the motor, can be independently arranged on the motor bracket 22, and further can reduce the axial occupied space of the whole motor assembly.
In order to facilitate the installation of the control circuit board 3, a plurality of screw holes 223 are formed in the side surface of the motor support 22, and the control circuit board 3 is fixed on the screw holes 223 through screws.
Furthermore, in the existing motor operation control, a control circuit board which is internally connected must be connected to a main control board of the whole fascia gun to realize the adjustment of motor operation, start and stop, frequency and the like, and the requirement on the reliability of an internal control circuit is higher. This application is independent back of coming out with the control circuit board 3 of motor, can be directly all integrate control circuit board 3 with motor control circuit and control switch 31 on to the main control panel of current manadesma rifle is cancelled, further practices thrift the space, has also improved the reliability of equipment control and operation.
