Abstract
The invention provides a stator of an alternating-current generator for vehicle with the improved stator slot structure of the stator, wherein the main spacing of the core of the stator is reduced, yet high output is obtained, by inserting coils and wedges through insertion portions in the slots and then using a jig such as a caulking jig to widen both the sides of the slots and prevent the coils and the like from coming off. Air gaps at proper intervals are formed in a generator and furthermore a rotor and a stator 1 are installed. At this time, straight partitions 3 sloped inward are formed inside the slots 2 in the stator 1, and coils and wedges are inserted into insertion portions 4 inside the slots 2. Thereafter, the ends of the straight partitions 3 are caulked to form anchoring portions 5 on both parts.
Description
The present invention relates to the manufacture method of the stator of generator, it has improved the structure of the stator slot in the vehicle-mounted dlternator, after the insertion portion by aforementioned grooves inserts coil and slot wedge, utilization forms the both sides of aforementioned grooves the instrument of ca(u)lk shape, process the master space that disengagings such as preventing the stator former coil reduces stator core by pressure-sizing, magnetic force with iron core produces the part increase simultaneously, can obtain high-output power.
Usually, in alternating current generator, be provided for driving the rotor of generator, and setting and aforementioned rotor keep certain air gap and produce the stator of electromagnetic force, on stator former, be formed for the groove of coil-winding, the two ends of the groove 201 that on the stator 1 of prior art, forms, as shown in Figure 1, the insertion section inlet of coil is made the T font, slot wedge and coil are set in aforementioned insertion section.
; the generator unit stator of aforementioned prior art; on the next door 301 at the two ends of stator slot, be formed with the standing part of T font; thereby the interval that makes aforementioned grooves becomes narrow; be difficult to be provided with coil and slot wedge thus; and have a following problem: i.e. effect owing to aforementioned narrow groove is subjected to bigger load; therefore; in the generator of high-output power; can produce the bad and pressure oscillation of resistance to pressure,, and worry that the coating layer of coil usually comes off because groove is narrow; risk of short-circuits is arranged, and make the decreased performance of generator.
The present invention develops in view of the variety of issue that exists in the above-mentioned prior art, its objective is provides a kind of generator unit stator manufacture method, generator unit stator by this method manufacturing makes the setting of coil and slot wedge become easy, and can reduce the master space of the iron core of stator former, farthest increase the area that magnetic force produces part, can obtain high-output power, and can prevent that resistance to pressure is bad, improve the power output of generator.
The manufacture method of the stator of generator of the present invention, it is characterized in that: rotor and stator are set on generator, and be formed with the air gap of predetermined distance between this rotor and the stator, inboard at the groove of stator former forms intilted linear next door, and coil and slot wedge are inserted be arranged at the insertion portion of aforementioned grooves inside after, pressure-sizing processing/shaping processing is carried out in the end in aforementioned linear pattern next door, form the standing part of both sides.
In addition, the manufacture method of the stator of generator of the present invention, it is characterized in that: rotor and stator are set on generator, and be formed with the air gap of predetermined distance between this rotor and the stator, inboard at the groove of stator former forms intilted linear next door, and coil and slot wedge are inserted be arranged at the insertion portion of aforementioned grooves inside after, pressure-sizing processing is carried out in the inboard of the end in aforementioned next door, form the standing part of a side.
Below, the present invention is described in detail with reference to the accompanying drawings.
Fig. 1 is the cutaway view of groove of the stator of prior art;
Fig. 2 is the cutaway view of groove of the stator of the embodiment of the invention;
Fig. 3 is the cutaway view of confined state of the present invention;
Fig. 4 is the cutaway view of other embodiment of the present invention.
Under the situation that the air gap that is formed with predetermined distance between rotor and stator and this rotor and the stator is set on the generator, inboard at the groove 2 of stator former 1 forms intilted linear next door 3, and after insertion portion 4 with coil 6 and slot wedge insertion aforementioned grooves inside, pressure-sizing processing is carried out in the end in aforementioned linear pattern next door 3, form the standing part 5 on both sides.
Also have, also can constitute the end in aforementioned next door 3 like this, promptly pressure-sizing processing is carried out in the inboard of the end in above-mentioned next door 3, form the standing part 501 of a side.
The present invention of Gou Chenging as described above, when shaping stator former 1, form next door 3 separately, to be formed with the groove 2 of appropriate intervals in inside, in each insertion portion 4 that forms by aforementioned next door 3, insert separately slot wedge and stator coil 6, be provided with in insertion under the state of aforementioned coil 6, carry out pressure-sizing processing from the inboard to the end in aforementioned next door 3, form standing part 5 or the standing part 501 that direction is used that both direction is used, like this, owing to make being provided with of aforementioned coil and slot wedge easy, easily, so before coil and pressure-sizing operation are set, also can carry out coating to the surface of stator, and, also go for not carrying out the type of aforementioned coating operation, form in the standing part process processing, can not go wrong by aforementioned pressure-sizing.
The present invention as described above has following characteristics: can be with the stator of aforementioned alternating current generator The groove of upper formation does more, being provided with by it under the state of coil and slot wedge, to two of groove End carries out pressure-sizing and processes to form standing part, and coil and slot wedge are arranged easily, and And the iron core of stator former can be expanded to greatest extent, and obtain high-output power, at coil Can prevent withstand voltage badly during insertion, the height that still can obtain generator after miniaturization to it is defeated Go out power.
