Description
Technical field
The present invention relates to a kind of motor stator and manufacture method thereof, particularly relate to a kind of motor stator manufacture method that improves the motor stator of electric efficiency and save material.
Background technology
In general, motor (Motor) is the machine that converts electric energy to kinetic energy, can be divided into converting electric energy to the rotary electromotor that rotatablely moves and converting electric energy to the straight-line compound motor that returns.Above-mentioned motor extensively is installed in nearly all household electrical appliance such as refrigerator, air-conditioning, washing machine, electric fan, dust catcher as power source.
See also shown in Figure 1ly, electric motor structure generally comprises the stator 10 that is installed on casing or the framework, coaxial package in stator 10 inner rotatable rotor 20 be wrapped in winding coil 30 in the described stator 10.
See also Fig. 2 and shown in Figure 3, existing motor stator 10 comprises the stator body 11 that is formed by most identical rectangle laminated plates 11 ' be fixed together.Wherein every laminated plate 11 ' central authorities be provided with centre bore 12 ', described laminated plate 11 ' go up towards centre bore 12 ' direction evenly distribute most identical T steels 13 ', adjacent two T steels 13 ' between form with the groove 14 of described centre bore 12 ' communicate '; Every laminated plate 11 ' four square position near be provided with hole 15 '.Additionally laminated plate 11 ' four right angles also can be processed into fillet.When the above-mentioned laminated plate 11 of most pieces ' be folded into a time-out, most piece laminated plates 11 ' formation body 11; Be positioned at most centre bores 12 on the same axis ' be formed for the holding through hole 12 of rotor; A most groove 14 ' formation elongated slot 14; A most T steel 13 ' formation T steel bar 13; Corresponding most hole 15 ' formation bolts hole 15.With majority above-mentioned laminated plate 11 ' be fixed together, promptly become motor stator with bolt passing through bolt hole 15.
See also Fig. 4.The method of making above-mentioned motor stator is generally: (1) selects material sheet material P, selecting width is the material sheet material P of 2 times of described laminated plate 11 ' width, relative position is beaten bullport h in material sheet material P both sides, the distance between adjacent two bullports equal laminated plate 11 ' length; (2) processing laminated plate 11 ', material sheet material P is installed on the metal pattern machine, to transfer the pin (not shown) again and insert described bullport h, be used for location and carry material sheet material P, in carrying material sheet material P process with laminated plate 11 ' mould time processing go out groove 14 ' with hole 15 '; (3) make laminated plate 11 ', with most laminated plates 11 on the material sheet material P that links together ' arrange two along the length direction of material sheet material P, broad ways is on the same line and cuts down simultaneously, overlapping putting together, be fixed to form with bolt passing through bolt hole 15 again is motor stator together.
Above-mentioned motor stator, though the smooth and easy motor stator that flows and prevent the flux loss effect of magnetic flux that can provide user one to have to make the electric current that flows into winding coil 30 to cause, really has progressive, but when using, reality but finds also to have in its structure some shortcomings, cause this motor stator in practical application, fail to reach best result of use, and its shortcoming can be summarized as follows:
If increase be wrapped in stator T steel 13 ' on winding coil twining amount and notch is opened when big, will reduce the flow of magnetic flux, and hinder the motor efficiency raising, so still there is inefficient defective in it.
Above-mentioned manufacture method, though the motor stator manufacture method that can provide user one to have effect easy to process, really has progressive, but when using, reality finds but that its method also has some shortcomings, the manufacture method that causes this motor stator is in practical application, fail to reach best result of use, and its shortcoming can be summarized as follows:
When making the laminated plate of motor stator with said method, line up 2 row on material sheet material P, the size of its wide cut and depth is fixed, so will enlarge area as raw-material above-mentioned material sheet material P if want to enlarge its size.In addition, if in order to increase the twining amount of the winding coil on the T steel 13 that twists in said stator 10, and enlarge the size of above-mentioned elongated slot 14, in order fully to guarantee the throughput of said stator 10 magnetic flux, and enlarge each limit of above-mentioned laminated plate 11 ' outer peripheral face and above-mentioned elongated slot 14 ' between distance, will enlarge as raw-material above-mentioned material sheet material P, cause the waste of raw material.
This shows that above-mentioned existing motor stator and motor stator manufacture method still have many defectives, and the assistant officer waits to be improved.
Because there is the defective that the high efficiency effect can't be provided in above-mentioned existing motor stator; Above-mentioned existing motor stator manufacture method exists can't provide energy savings, defective the design people is based on abundant practical experience and professional knowledge cheaply, actively studied innovation, through constantly research, design, and after studying sample and improvement repeatedly, create the present invention and the manufacture method thereof that have practical value finally.
