Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to Fig. 1 ~ 5, one laminates integral type stator 100, comprise stator core 1, described stator core includes the lamination 10 that multiple integrated punching is formed, described multiple lamination 10 laminates mutually, and being welded together to form described stator core 1, the front end of described stator core is fitted with front retainer 3, rear end is fitted with rear retainer 2, and on the inner headed face of described lamination 10, integrated punching is formed with iron-core coil installation portion 104.
In specific implementation, described lamination 10 can pass through the direct stamping steel plate of Sheet Metal Forming Technology, form the shape shown in Fig. 4, then overlap together welding and can form described stator core, so equal stator cage and magnetic pole as entirety, then coiling stator excitation winding on stator core, so just achieve by the original Split type structure being fixed magnet exciting coil by screw fixed magnetic pole, change the overall structure of direct coiling excitation winding on stator core into, thus eliminate and punch on stator cage, by the laborious steps of fixed coil again after screw fixed magnetic pole, simplify installation manufacture craft, and stopped screw loosening and the too low mill pole caused of diameter of stator bore circularity precision, noise, the problems such as power drop.
In specific implementation, the iron-core coil installation portion 104 of described lamination 10 is four, be arranged on the inner headed face of described stator lamination 10 symmetrically, the outside of this iron-core coil installation portion 104 comprises a plane and is positioned at two identical lean-in inclined-planes of the angle of inclination of these plane both sides, roughly in Eight characters shape, be convenient to coil 4 is installed, after multiple described lamination 10 laminates welding, described iron-core coil installation portion 104 overlaps together the overall coil fixing structure for fixed coil of formation one.
Further, the stator core formed to realize poststack welding is connected with forward and backward retainer, the iron-core coil installation portion 104 of described lamination 10 is provided with the pilot hole 102 of circular pilot hole 103 and flat hole or perhaps ellipse, like this, after stator core is formed, stator core just define for carrying out with described front retainer, rear retainer the stator core pilot hole 12 that assembles, corresponding, described front retainer, rear retainer are provided with the assembling inserted link of corresponding described stator core pilot hole.
Because described stator core pilot hole 12 is formed by the pilot hole 102 of the pilot hole 103 of above-mentioned circle and flat hole or perhaps ellipse, therefore this stator core pilot hole is similarly two circular holes and two flat holes or perhaps slotted eye, symmetrical between two and be evenly arranged on the front/rear end of the described stator core overlapped together, certainly, described front retainer, the assembling inserted link of the described stator core pilot hole of the correspondence that rear retainer is provided with, correspondence comprises the first inserted link 32 that two are adapted to described circular port, two the second inserted links 31 being adapted to described circular port.
It should be noted that, the periphery of described lamination 10 is also provided with symmetrical concave curvilinear portion 101.Preferably, it is four, be arranged on the periphery of lamination 10 symmetrically and evenly, after multiple described lamination 10 laminates, described concave-arc part 101 forms the welding groove 11 being used for reinforcement of weld on the periphery of described stator core 1, and welding groove 11 is for using multiple lamination 10 reinforcement of weld by welding manner.
Because described welding groove 11 is superposed by described concave curvilinear portion 101 to be formed, therefore, the quantity of described welding groove 11 is consistent with the quantity of the described concave curvilinear portion 101 on single described lamination 10, is similarly four, is evenly arranged on the periphery of described stator core 1.
In order to the installation realizing coil is fixed, on the inwall of described front retainer, rear retainer, corresponding described iron-core coil installation portion 104 is provided with retainer coil installation portion, and described coil 4 is installed in stator by the iron-core coil installation portion 104 of this retainer coil installation portion and lamination.
It is adopt Sheet Metal Forming Technology directly to make stator lamination by steel plate stamping that the utility model laminates integral type stator, then be overrided to form by some laminations, make stator core, equal casing and magnetic pole as entirety, then coiling stator excitation winding on stator core, so just achieve by the Split type structure being originally screwed magnetic pole and fixing magnet exciting coil, change the overall structure of direct coiling excitation winding on stator core into.
The utility model laminates unitary stator by employing, has following beneficial effect:
1, Quality advance, has stopped screw loosening and the too low problem such as mill pole, noise, power drop caused of diameter of stator bore circularity precision.
2, simplify stator manufacture craft, improve efficiency.Old stator structure casing needs machine work and electroplating processes, and magnetic pole needs the shaping then tapping of casting of metals, and coiling stator exciting coil assembly magnetic pole screw is combined into field frame assembly; And adopt and new laminate integral type stator, only need on the stator core laminated direct coiling stator exciting coil.
3, reduce stator cost, iron loss and copper loss can be reduced.Through the starter of plant produced contrast equal-wattage, adopt new laminate integrated stator structure on year-on-year basis old stator structure in iron loss, lower 20%, reduction by 10% on copper loss, stator cost reduces by 10% on year-on-year basis.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
