Two adjacent silicon steel sheets are usually connected by welding. This increases the eddy current loss generated by the stator and the rotor, thereby causing the temperature inside the motor to rise, increasing the energy consumption of the motor and reducing the power of the motor.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0048] Referring to Figures 1 to 10 , a motor component is disclosed, which comprises a plurality of silicon steel sheets 1 stacked with each other and an adhesive layer 2 between two adjacent silicon steel sheets 1 to fix and connect the two adjacent silicon steel sheets 1 by the adhesive layer 2, and the plurality of silicon steel sheets 1 fixed together by the adhesive layer 2 constitute a stator or a rotor of a motor.

[0049] It should be noted that in the prior art, the rotor and the stator of the motor are formed by stacking and fixedly connecting a plurality of silicon steel sheets 1, and the rotor and the stator are only different in shape of the silicon steel sheets 1, and the above-mentioned "a plurality of silicon steel sheets 1 fixed together by the adhesive layer 2 constitute the stator or the rotor of the motor" refers to not limiting the shape of the silicon steel sheet 1, which can be, for example Figure 1 as shown in the stator structure, or Figure 2 as shown in the rotor structure; that is, when the silicon steel sheet 1 is in the shape of the stator, a plurality of silicon steel sheets 1 are fixedly connected by the adhesive layer 2 to finally form the stator; and when the silicon steel sheet 1 is in the shape of the rotor, a plurality of silicon steel sheets 1 are fixedly connected by the adhesive layer 2 to finally form the rotor.

[0050] Since the silicon steel sheet 1 in the present application is fixedly connected by the adhesive layer 2, the eddy current loss caused by the welding method is avoided, thereby reducing the temperature inside the motor installed with the motor component, reducing the energy consumption of the motor and ensuring the power of the motor; at the same time, the reprocessing of the silicon steel sheets 1 that need to be fixedly connected together due to the welding method for fixing the silicon steel sheets 1 is avoided, thereby reducing the production cost of the motor component and improving the production efficiency of the motor component.

[0051] The present application does not make specific limitation on the forming method of the adhesive layer 2, preferably, the adhesive layer 2 is formed by insulating glue coated on the end surface of the silicon steel sheet 1, on the one hand, realizing the fixed connection of the adjacent two silicon steel sheets 1 by the adhesive method, on the other hand, strengthening the insulation effect between the adjacent two silicon steel sheets 1, to further reduce the loss of the motor component, thereby further reducing the internal temperature of the motor installed with the motor component, further reducing the energy consumption of the motor and further ensuring the power of the motor.

[0052] In other embodiments, the adhesive layer 2 can also be formed by other glue coated on the end surface of the silicon steel sheet 1.

[0053] In a preferred embodiment, the silicon steel sheet 1 is provided with a positioning portion and a matching portion, and the positioning portion on one of the adjacent two silicon steel sheets 1 matches the matching portion on the other silicon steel sheet 1 to position the adjacent two silicon steel sheets 1.

[0054] Specifically, when the silicon steel sheet 1 is assembled, the positioning portion on one of the adjacent two silicon steel sheets 1 matches the matching portion on the other silicon steel sheet 1 to realize the positioning of the adjacent two silicon steel sheets 1, thereby reducing the assembly difficulty of the silicon steel sheet 1 and improving the production efficiency of the motor component.

[0055] The structure of the positioning portion and the matching portion is not limited in the present application, which can adopt any one of the following embodiments:

[0056] In the embodiment, referring to Figures 1 to 4 , the positioning part is a positioning protrusion 11 arranged on the silicon steel sheet 1, and the cooperating part is a cooperating groove 12 arranged on the silicon steel sheet 1, and the positioning protrusion 11 can be matched with the cooperating groove 12.

[0057] Specifically, when assembling the silicon steel sheet 1, the positioning protrusion 11 on one of the two adjacent silicon steel sheets 1 extends into the cooperating groove 12 of the other silicon steel sheet 1, so that the cooperation of the positioning protrusion 11 and the cooperating groove 12 positions the two adjacent silicon steel sheets 1, thereby reducing the assembly difficulty of the silicon steel sheet 1, improving the assembly efficiency of the silicon steel sheet 1, and reducing the production cost of the electrical component; meanwhile, the assembly precision of the silicon steel sheet 1 is improved, thereby improving the production quality of the electrical component.

[0058] Further, referring to Figure 5 , the positioning protrusion 11 includes a first positioning protrusion 111 extending along the radial direction of the silicon steel sheet 1 and a second positioning protrusion 112 extending along the circumferential direction of the silicon steel sheet 1, and the cooperating groove 12 includes a first cooperating groove 121 and a second cooperating groove 122, the first positioning protrusion 111 can be inserted and matched with the first cooperating groove 121 to position the silicon steel sheet 1 in the circumferential direction, and the second positioning protrusion 112 can be inserted and matched with the second cooperating groove 122 to position the silicon steel sheet 1 in the radial direction.

[0059] Specifically, when assembling the silicon steel sheet 1, the first positioning protrusion 111 on one of the two adjacent silicon steel sheets 1 extends into the first cooperating groove 121 of the other silicon steel sheet 1, so as to position the two adjacent silicon steel sheets 1 in the circumferential direction, and the second positioning protrusion 112 on one of the two adjacent silicon steel sheets 1 extends into the second cooperating groove 122 of the other silicon steel sheet 1, so as to position the two adjacent silicon steel sheets 1 in the radial direction, thereby further reducing the assembly difficulty of the silicon steel sheet 1, improving the assembly precision of the silicon steel sheet 1, and further improving the production quality of the electrical component.

[0060] Preferably, the first positioning protrusion 111 and the second positioning protrusion 112 are both in a V-shaped strip structure, so as to simplify the structural design of the first positioning protrusion 111 and the second positioning protrusion 112, and make the first positioning protrusion 111 and the second positioning protrusion 112 both formed by stamping the silicon steel sheet 1, thereby reducing the production cost of the silicon steel sheet 1.

[0061] In the embodiment, referring to Figures 6 to 8 , the positioning part is a positioning arm 13 arranged on the side of the silicon steel sheet 1, and the cooperating part is a cooperating notch 14 arranged on the side of the silicon steel sheet 1, and the positioning arm 13 can be matched with the cooperating notch 14.

[0062] Specifically, when the silicon steel sheets 1 are assembled, the positioning arms 13 on one silicon steel sheet 1 extend into the matching notches 14 on the other silicon steel sheet 1, so that the matching of the positioning arms 13 and the matching notches 14 realizes the positioning of the two adjacent silicon steel sheets 1, thereby avoiding the mispositioning of the two adjacent silicon steel sheets 1, and further improving the production quality of the electric machine component.

[0063] The application does not make specific limitations on the forming mode of the positioning part and the matching part. Preferably, the positioning part is formed by stamping one end face of the silicon steel sheet 1, so that the end of the silicon steel sheet 1 away from the positioning part forms the matching part, that is, the matching part is formed by stamping the positioning part, thereby reducing the production difficulty of the silicon steel sheet 1, simplifying the production steps of the silicon steel sheet 1, improving the production efficiency of the silicon steel sheet 1, and at the same time ensuring that the matching part is opposite to the positioning part, so as to ensure that the two adjacent silicon steel sheets 1 can be aligned in position when the positioning part and the matching part are matched, thereby further improving the production quality of the electric machine component.

[0064] In other embodiments, the positioning part and the matching part can also be structures separately provided on the end face of the silicon steel sheet 1.

[0065] In a preferred embodiment, referring to Figure 9 , the end face of the silicon steel sheet 1 is provided with a glue containing groove 15, which is arranged along the circumference of the silicon steel sheet 1, so that when the two adjacent silicon steel sheets 1 are pressed together, the excess glue can enter the glue containing groove 15 for storage, which on the one hand can increase the connection stability of the two adjacent silicon steel sheets 1, and on the other hand can avoid the situation that the excess glue flows to the outside of the silicon steel sheet 1, thereby improving the appearance quality of the electric machine component.

[0066] Further, the glue containing groove 15 is arranged at the outer side edge of the silicon steel sheet 1, so that the glue flowing to the outer side of the silicon steel sheet 1 can enter the glue containing groove 15, thereby avoiding the situation that the excess glue flows to the outside of the silicon steel sheet 1, and further improving the appearance quality of the electric machine component.

[0067] In a preferred embodiment, referring to Figure 10 , the end face of the silicon steel sheet 1 is provided with a plurality of glue containing grooves 15, which are arranged outward from the center of the silicon steel sheet 1 and at an angle with the radial direction of the silicon steel sheet 1, so that the glue entering the glue containing groove 15 can flow along the extension direction of the glue containing groove 15, so that the glue is more uniform between the two adjacent silicon steel sheets 1, thereby ensuring the bonding stability of the two adjacent silicon steel sheets 1.

[0068] The application does not make specific limitations on the forming mode of the glue containing groove 15, which can be formed by stamping the silicon steel sheet 1, or can be formed by milling the silicon steel sheet 1. Since the thickness of the silicon steel sheet 1 is small, the depth of the glue containing groove 15 is shallow, thereby making the forming mode of the glue containing groove 15 more diversified.
