Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, vibrate a faint direct current machine, comprise rear end cap 4, it is characterized in that: described rear end cap 4 interference fit is connected with plastic packaging stator 1 seam, four stagger angles that plastic packaging stator 1 cylindrical is uniform are provided with shock-absorbing foot 5, in the middle part of plastic packaging stator 1, are provided with rotor assembly 2; Rotor assembly 2 rear portion is welded with control loop 3; Described rotor assembly 2 comprises support iron core 201, yoke 202, magnet steel 204, and described support iron core 201 periphery is provided with rubber 203, and rubber 203 periphery is provided with yoke 2, and yoke 2 periphery is evenly equipped with several magnet steel 204; Described a kind ofly vibrate faint direct current machine, it is characterized in that: described plastic packaging stator 1 is formed by BMC molding material plastic packaging by stator core wire-winding unit, between stator lamination, between the adjacent space of coiled wire-wound coil, fill full BMC form an organic whole; Described a kind ofly vibrate faint direct current machine, it is characterized in that: described yoke 202 inner circle is evenly provided with 4 dovetail boss, the angle of each dovetail boss side and yoke 202 is provided with 1 location hole B; Yoke 202 cylindrical is evenly provided with several dovetail grooves; Described a kind ofly vibrate faint direct current machine, it is characterized in that: the dovetail groove in described yoke 202 and the gap between magnet steel 204 and the gap location formed between adjacent magnet steel 204 cylindrical are marked with PPT engineering plastics 205; According to claim 1ly a kind ofly vibrate faint direct current machine, it is characterized in that: described support iron core 201 cylindrical is evenly provided with 4 semicircle location hole C, support on iron core 201 cylindrical and be evenly provided with 4 dovetail boss.
During concrete enforcement, 1), yoke 202 puts into mould together with magnet steel 204, inject the injection mo(u)lding of PPT engineering plastics 205, described PPT engineering plastics 205 are filled in the thickness difference space that gap between yoke 202 and magnet steel 204 and magnet steel 204 cylindrical convexity are formed, injection mo(u)lding fixes magnet steel 204 for protecting muscle, mould is provided with multiple decile boss and matches with the location hole A on magnet steel 204, for supporting and location magnet steel 204, the fastening encapsulation magnet steel 204 of effective thickness can be formed at magnet steel about 204 after making injection moulding, by this step, yoke 202, magnet steel 204 forms an entirety via PPT engineering plastics 205.2), support iron core 1 is put into rubber mold together with the yoke magnetic steel component of injection formed, inject rubber 203 hot briquetting, described rubber filling is in the confined space that support iron core 201, yoke 202, mold cavity are formed, iron core 201 and yoke magnetic steel component compact siro spinning technology will be supported, for bearing the vibration weakening radial direction, axial both direction, play very important damping effect.Mould is arranged multiple alignment pin (product being location hole B and location hole C), for locating fixed support iron core 201, yoke 202, ensure the axiality supporting iron core 201 endoporus and whole rotor assembly 2 cylindrical simultaneously, make rotor assembly 2 air gap even, improve rotor assembly 2 balance quality.Rotor assembly 2 being provided with and waiting divided diamond concave station 209 more, for compressing the support arm supporting iron core, yoke 202 during mould locked mode, gap between core stamping sheet while playing the role of positioning, can be extruded, can prevent because iron core folds the motor oscillating that riveting tightly do not cause.The rotor assembly 2 formed by above step, presses rotating shaft, bearing, directly just can drop into assembling after magnetizing.During motor assembling, first rotor assembly 2 is loaded plastic packaging stator 1, weld control board 3 again, rear end cap 4 interference fit press-in plastic packaging stator 1 seam ensures metal (upper room concentric, further ensure air gap between rotor and stator evenly, ensure the balance of rotor operation process, last given shape shock-absorbing foot 5 of installing on plastic packaging stator 4 stagger angles reaches the object absorbing vibration, avoids the load noise formed because installing the reason such as reason, motor resonance.
Above-mentioned plastic packaging stator 1 is formed by BMC molding material plastic packaging by stator core wire-winding unit, it fills full BMC and forms an organic whole between stator lamination, between the adjacent space of coiled wire-wound coil, the vibration because there being the reason such as gap, coiled wire-wound coil energising to cause between lamination can be avoided, add that BMC damping is large, power frequency is high, effectively can avoid resonance point when electric machine rotation produces noise.
After installation, through test, no-load running is radial, axial vibratory displacement is all less than 10 μm, far below the standard of country about small-sized electric machine vibration; Through reality installation test, complete machine oscillation, level of noise are all far smaller than national standard, reach super-silent effect.
