Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Stator core first embodiment
Stator core is formed in circumferentially mutual assembly unit by a plurality of profiles of tooth unit; Each profile of tooth unit is range upon range of and form by the profile of tooth dice of some; It has certain thickness, and Fig. 2 is the plane graph of profile of tooth unit 1, and every profile of tooth dice all has shape shown in Figure 2.As shown in Figure 2, profile of tooth unit 1 comprises a tooth portion 6 that is used to wind the line, and the one of which end is provided with the anti-avulsion retaining that is used to prevent the coil slippage, and the other end is for forming the yoke portion 7 of stator core periphery, and the winding slot separation is in the left and right sides of tooth portion 2.The yoke portion 7 of profile of tooth unit 1 is provided with the location notch 8 as the location division away from a side of tooth portion, and the shape of location notch 8 can freely be provided with as required, like dovetail shaped, trapezoidal, triangle, circular arc etc., as long as can realize that the positioning instant of profile of tooth unit 1 can.The button point 9 that every profile of tooth dice same position is protruded outside oriented primary flat and shape is identical is formed between each profile of tooth dice of profile of tooth unit 1 and is aimed at laminated together each other through button point 9.The profile of button point 9 also can freely be provided with, and is set to cube or segment or prismatoid like profile, fastens each other between each profile of tooth dice as long as can realize.
In Fig. 2; The left end of yoke portion 7 promptly is provided with projection 4 along its outer rim on the part of the periphery of the formation stator core of yoke portion 7; Projection 4 comprises bridge part 41 and arc sections 42; The right-hand member of yoke portion 7 is provided with the groove 5 that coincide with projection 4 shapes along its outer rim, and groove 5 comprises arc sections 52 and the part 51 that matches with bridge part 41.The setting that bridge part 41 reaches the part 51 corresponding with it increases the Mosaic face contact area, reduces the generation of leakage field.Wherein the arc sections 52 of the arc sections 42 of projection 4 and groove 5 be set to intersect with the stator core periphery and pairing central angle greater than 180 degree, be 180 °+β.On the projection 4 near the part of stator core axis along stator core be A radially apart from the distance of stator core periphery, the chord length that groove 5 opening parts are corresponding is B.
When B is set more than or equal to A, the projection 4 of profile of tooth unit 1 can be in primary flat from the open side of the groove 5 of another profile of tooth unit 1 in the groove 5 that inserts, as shown in Figure 3, form relatively turnable planar hinge.Two profile of tooth unit 1 can rotate to an angle relatively; As long as the chord length of the arc sections 42 of projection 4 and arc sections 52 contact-making surfaces of groove 5 is greater than the corresponding chord length B in slot opening place; Even when in primary flat, applying the power that makes the separation of two profile of tooth unit; Two profile of tooth unit 1 still can keep flexibly connecting and not get loose, and this connects the scope that does not get loose is 2 β, as shown in Figure 4; When the chord length of the arc sections 42 of projection 4 and arc sections 52 contact-making surfaces of groove 5 during, apply the power that two profile of tooth unit are separated along direction projection 4 is thrown off in groove 5 perpendicular to slot opening less than the corresponding chord length B in slot opening place.
When being set to B less than A, the projection 4 of profile of tooth unit 1 can not be in primary flat from the open side of the groove 5 of another profile of tooth unit 1 to insertion.At this moment, projection 4 can only be above or below the primary flat along stator core axially in the groove 5 that embeds another profile of tooth unit 1, form relatively turnable planar hinge.Because B less than A, applies power along any direction two profile of tooth unit that are connected 1 are separated in primary flat, two profile of tooth unit can rotate each other in the maximum magnitude that does not interfere and can not get loose.
Fig. 5 shows the sketch map that a plurality of profiles of tooth unit 1 is interconnected to form chain.When being combined into the chain type stator core, each profile of tooth unit 1 can be in certain angle like free reversed torsion as the chain, can a large amount of profiles of tooth unit 1 be coupled together disc type and deposit, conserve space can realize the automatic assembly line operation simultaneously, to enhance productivity.
Fig. 6 is the diagram that several profile of tooth unit 1 are assembled into the stator core of full circle, and the stator core that is assembled into full circle can not stay breach in yoke portion 7, and during design, yoke portion 7 size diametrically can be less relatively, saves the lamination material.
When making motor, its production stage is following:
A) subpunch is made the profile of tooth dice that forms profile of tooth unit 1; Because the structure of profile of tooth unit 1 is simple relatively; But multiple row punching out profile of tooth dice is laminated together to form profile of tooth unit 1 with the multi-disc tooth shape dice then to raise the efficiency, and the opening of the groove 5 through a profile of tooth unit 1 inserts the projection 4 of another profile of tooth unit 1; Or above or below the primary flat of this profile of tooth unit 1, embed the projection 4 of another profile of tooth unit 1 in the groove 5 of these profile of tooth unit 1, form relatively turnable planar hinge;
B) connect next profile of tooth unit 1 successively, have the long-chain of certain-length until formation;
C) in the tooth portion 6 of each profile of tooth unit 1 insulation framework is installed, and carries out the coiling of coil in the tooth portion of each profile of tooth unit through open coil winding machine;
D) after coiling is accomplished, a plurality of profiles of tooth unit circumflexion stator in the intercepting long-chain;
E) and then general assembly such as the rotor of packing into form motor.
Make the coiling that motor also can be employed in single profile of tooth unit 1 enterprising column rule circle and directly be assembled into the method for circular stator then, or be assembled into the coiling of carrying out coil behind the stator core of full circle again.
Stator core second embodiment
Similar among the structure of stator core and first embodiment in the present embodiment, the arc sections that just forms projection and groove is made up of two sections circular arcs.
Like Fig. 7 and shown in Figure 8, the two ends of the yoke portion 7 of profile of tooth unit 1 are respectively arranged with projection 4 and groove 5 along its outer rim.Wherein the arc sections of projection 4 is formed by two sections isocentric circular arc 43 and 44, and the arc sections of groove 5 is formed by two sections isocentric circular arc 53 and 54.Wherein circular arc 43 and 53 pairing radiuses are less than circular arc 44 and 54 pairing radiuses.Can improve the mechanical strength that profile of tooth unit 1 pieces together circular stator core, reduce distortion.When utilizing present embodiment to produce motor also with first embodiment in similar.
More than be the preferred embodiment of the utility model, the utility model includes but not limited to this, and the technical scheme of modes such as all employing equivalent transformations all drops in the protection range of the utility model.
