Detailed Description
In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, and bottom" is generally used with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction.
In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between the various embodiments can be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not be within the protection scope of the present invention.
Fig. 1 and 2 are schematic structural views of a wire outlet mechanism of a flat wire motor according to an embodiment of the present invention. In fig. 1 and 2, the outlet mechanism may include a neutral bar 10 and a terminal block 20. Wherein the neutral bar 10 may be structured as shown in fig. 1, and the connection terminal 20 may be structured as shown in fig. 2.
Specifically, in fig. 1, the neutral row 10 may include an arc plate 11 and a post 12. The arc plate 11 can be perpendicular to the axis of the winding of the flat wire motor and embedded in the end face of the winding. The terminals 12 may be provided on the intrados and extrados of the arc plate 11 for connection with the winding. In addition, the terminals 12 provided on the intrados and extrados of the arc plate 11 may be arranged in a staggered manner so as to be inserted into the connection terminals 20. Further, in order to enable the neutral bar 10 to be embedded deeper into the end face of the winding, as shown in fig. 1, the terminal 12 may be vertically disposed on the side of the arc plate 11 away from the winding. The arc plate 11 may be a semicircular arc plate to further conform to the shape of the winding.
In fig. 2, the connection terminal 20 may include a connection main board 21, an access wire 22, and an outgoing wire 23. The wiring main board 21 may be disposed perpendicular to the plane of the arc board 11. The access line 22 may be disposed in the middle of the wiring main board 21 and far away from one side of the arc-shaped board 11, and is used for accessing an external wiring voltage. The outgoing lines 23 may be provided at both ends of the connection main board 21 for connection with the windings. Via this connection terminal 20, as shown in fig. 2, the connection voltage introduced via the inlet line 22 can be branched into the winding and finally connected via the other end of the winding to the neutral bank 10.
Fig. 3 is a schematic view of the relative positions of the neutral bar 10 and the connection terminal 20 according to an embodiment of the present invention. In fig. 3, the neutral bar 10 and the connecting terminals 20 can be insulated from one another, so that the connection voltage applied by the connecting terminals 20 can be fed to the neutral bar 10 via the terminal pins 12 after passing through the windings. In addition, in order to avoid the different connection terminals 20 from interfering with each other, when a plurality of connection terminals 20 are arranged in the neutral bar 10, the different connection terminals 20 may not cross each other. In this embodiment, the specific number of the terminals 20 may be a plurality of values known to those skilled in the art. In a preferred example of the invention, considering that the supply voltage commonly used for flat wire motors is a three-phase voltage, the terminals 20 may be at least three, each of which terminals 20 may be used for connection to one of the three-phase voltages. The outlet mechanism shown in fig. 3 is capable of being embedded in the end face of the winding by splitting the single outlet mechanism, which is conventional in the prior art, into the neutral bar 10 and the terminal block 20, and designing the neutral bar 10 to be an arc shape similar to the end face of the winding. Due to the front-mounted mat of the neutral bar 10, space is made available on the end face of the winding for the terminal 20 to be mounted, so that the terminal 20 can also be inserted into the end face of the winding. The wire outlet mechanism provided by the invention ensures that the shape of the wire outlet mechanism is not limited to the form of the winding by combining the neutral bar 10 and the wiring terminal 20. Compared with the conventional wire outlet mechanism in the prior art, the wire outlet mechanism has higher universality, and the design cost and the design volume of the wire outlet mechanism of the flat wire motor are reduced.
Fig. 4 shows an exploded view of the winding mechanism of a flat wire motor according to an embodiment of the present invention. In this fig. 4, the winding arrangement may include an outgoing line arrangement (neutral bar 10 and connection terminals 20), a plurality of straight line section conductors 31, a hairpin 32 and a commutation conductor 33 as shown in fig. 1 to 3. Each of the linear conductors 31 may be arranged in parallel, and the linear conductors 31 may be divided into at least three groups so as to be used as a line loop of each phase of the externally connected three-phase voltage. The hairpin end 32 may be connected to one end of two adjacent straight-line conductors 31 in the same group, so as to connect the straight-line conductors in the same group end to form a circuit loop. The commutation conductor 33 may be connected to the other ends of two adjacent straight-line segment conductors 31 in the same group, and the other end of the commutation conductor 33 connected to the first and last straight-line segment conductors 31 of each group (the end not connected to the straight-line segment conductors 31) may be connected to the terminal 12 of the outlet mechanism.
In one embodiment of the present invention, the winding mechanism may further include a stator core 34 in order to fix the coil of the winding as shown in fig. 4. As shown in fig. 4, the stator core 34 may be a cylindrical housing with a hollow top and a hollow bottom, and the inner wall of the cylindrical housing may be provided with a rectangular groove 35 for accommodating the linear conductor 31. Wherein, the specific number of the rectangular slots 35 can be determined according to the length of the coil of the winding mechanism. In one example of the present invention, the number of the rectangular grooves 35 may be 48. And the 48 rectangular grooves 35 can be uniformly distributed on the inner wall of the cylindrical shell. In addition, considering that the adjacent straightaway conductors 31 need to be insulated from each other, 2n straightaway conductors 01 may be installed in each rectangular slot 34. Wherein n may be a positive integer. The 2 linear conductors 01 may be disposed near the bottom and the opening of the rectangular slot 35, respectively. Further, since the stator core 34 is generally made of silicon steel by pressing, in order to insulate the linear conductors 31 from each other and insulate the linear conductors 31 from the stator core 34, the rectangular slot 35 may be provided with an insulating paper 36.
In one embodiment of the present invention, to facilitate the connection of the commutation conductors 33 and the hairpin ends 32, the linear conductors 31 may be arranged in a cylindrical shell, and each group of linear conductors 31 is disposed at a distance from each other. The commutation conductor 33 may include two straight wires having opposite inclination directions and a bridge line for connecting the two straight wires, and the two straight wires are connected to the other ends of the adjacent two straight-line segment conductors 31, respectively. In this embodiment, the straight conductor on the commutation conductor 33 connected to the straight section conductor 31 is in an oblique direction, so that the height of the wiring is further reduced compared to a conventional vertical wiring. In addition, since the two straight wires connected to the two straight-line conductors 31 are inclined in opposite directions, the influence of the magnetic field between the wires is reduced, and the suppression current due to magnetic induction is reduced.
In another aspect, the present invention further provides a flat wire motor, where the flat wire motor includes any one of the winding mechanisms described above and a flat wire motor body.
According to the flat wire motor and the wire outlet mechanism and the winding mechanism thereof, the wire outlet mechanism is designed into the neutral row and the wiring terminal, the neutral row is semicircular, so that the neutral row can be embedded in the wire winding end face of the flat wire motor, and the wiring terminal and the neutral row are perpendicular to each other, so that the neutral row embedded in the flat wire motor can be connected with external wiring voltage. Compared with the prior art, the flat wire motor, the wire outlet mechanism and the winding mechanism thereof provided by the invention can reduce the design volume of the flat wire motor and the design cost of the flat wire motor.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention. Including each of the specific features, are combined in any suitable manner. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
