Embodiment
In order to allow those skilled in the art understand better technical scheme of the present invention, below the present invention is further elaborated.
A kind of small-size vibration motor, comprises stator pack 1, round rotor group 2, end cap group 3, and stator pack 1 comprises permanent magnet 13 and the stator bearing 12 of stator casing 11, laminating stator casing inwall, and this permanent magnet is the permanent magnetic material after magnetizing; End cap group 3 comprises end cap 31, be embedded in end cap 31 bearing with end cover 32, brush 33 form with energising terminal 34, and brush 33 is arranged on both sides, bearing with end cover 32 center, and brush 33 is connected with external direct current power supply by energising terminal 34; Described rotor set 2 comprises slotless cylindrical shape support portion 21, coil 22, commutator 24 and central shaft 23, slotless cylindrical shape is the relative and existing slot type silicon steel sheet that has, existing slot type silicon steel sheet is useful on the draw-in groove of winding around on the surface of silicon steel sheet, and 21 surfaces, support portion are for being wound around the draw-in groove of winding around, support portion 21 is magnetic conduction or non-magnet material.End cap group 3 is located at the end of central shaft 23 and stator casing 11, it is outer to oscillator 4 that central shaft stretches out stator casing, oscillator 4 eccentric bushings are located on central shaft 23, described coil 22 is first wrapped in line on the mould of setting, the coil that taking-up winds is mediated and is flattened slabbing, forms end to end chip coil, and coil 22 is centered around 21 outsides, support portion, commutator 24 is arranged on the outside of central shaft 23, and commutator 24 is connected with coil 22.Be provided with the support 5 making in fitting on PCB in the outer survey of stator casing, support 5 surfaces have one deck to be easy to the material of scolding tin.
When after motor terminal 34 energisings, can reach by the exchange between brush 33 and commutator 24 coil 22 of rotor set 2, when producing magnetic field after coil 22 energisings of rotor set 2.Permanent magnet 13 mutual effects of the magnetic field of rotor set 2 and stator pack 1 and produce the electromagnetic force of fixing a direction, because central shaft 23 is fixed in bearing with end cover 32 and stator bearing 12, so will making rotor set 2 produce around central shaft 23 is continual, the electromagnetic force producing rotatablely moves.In the time changing terminal voltage direction, now motor can be to motion in the other direction.
Stator casing and cylindrical magnetic conduction or non-magnetic support portion are all parts for motor magnetic circuit, because there is " magnetic conduction " or " non-magnetic " two kinds support portion, therefore the magnetic force size producing will form two kinds of states: in the time that support portion is magnetic conductor, now motor electromagnetic hole magnetic field is little, motor can drive large load, and the vibratory output of non-magnetizer support portion wants large relatively; In the time that support portion is non-magnetizer, now motor air-gap is large, and motor can only drive relatively little load, and the vibratory output of magnetic conductor support portion is little relatively.
The invention provides a kind of small-size vibration motor, this vibrating motor employing slotless cylindrical shape magnetic conduction or not magnetic conduction support portion have replaced traditional silicon steel card slot type support portion, the formation of coil is by being directly wrapped on strutting piece and being improved to first line is wrapped on mould in the past, the coil twining is taken off, mediate to flatten after slabbing again and end to endly fit in slotless cylindrical shape magnetic conduction or not on magnetic conduction support portion, be convenient to install coil, operation sequence is simplified, and has improved production efficiency.This vibrating motor simple in structure, volume is small, is suitable for being fitted on pcb board, can be for the prompt facility of the communication terminal product such as mobile phone, panel computer or effective prompting function, improved sensitivity, rotor set the phenomenon that can avoid air gap large is set, improved the vibratory output of motor.Rack surface is the material that is easy to after treatment scolding tin, due to motor bracket itself there is automatic tin soldering function, the present invention can directly be fixed on the wiring boards such as mobile phone through Reflow Soldering, makes the design of communication product and produces simpler.
When on motor band when other load, motor can play other function, therefore the present invention specially plants and is not limited to vibrating motor, is also not limited to patch vibration motor, and other similar this patent scheme is all the scope that this patent will be protected.
It is more than preferably implementation of the present invention; it should be noted that; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making according to the present invention various corresponding changes and distortion, but these changes and distortion all should belong to the protection range of the appended claim of the present invention.
