Detailed Description
Fig. 1-7 are schematic block diagrams of a motor and its components according to one embodiment of the present invention. As shown in fig. 1-7. The present embodiment provides a motor 100, and the motor 100 may include a stator core 10 and a housing 20. The stator core 10 is formed by stacking a plurality of annular core laminations 11 in a staggered manner. The main structure of the stator core 10 is formed by stacking a plurality of core laminations 11. After the plurality of core segments 11 are stacked, a flow channel is formed between the core segments 11 and the housing 20, and a liquid (e.g., a cooling liquid) may flow in the flow channel to cool the motor 100.
Because the stator core 10 of this embodiment is formed by stacking a plurality of core laminations 11, the manufacturing process of the core laminations 11 is simple, and the manufacturing cost is low.
As a specific example, the stator core 10 may be formed by alternately stacking at least one circular first core lamination 111 and at least one circular second core lamination 112. The housing 20 is wrapped around the stator core 10 and attached to the outer periphery of the stator core 10 to form a flow channel, so that the liquid flows in the flow channel. The outer peripheral surfaces of the first iron core stamped sheet 111 and the second iron core stamped sheet 112 are different in structure, so that the flow channel penetrates through the peripheries of the first iron core stamped sheet 111 and the second iron core stamped sheet 112, and then liquid can flow between the first iron core stamped sheet 111 and the second iron core stamped sheet 112 in a series flow mode.
Specifically, the motor 100 in this embodiment includes the stator core 10 and the housing 20, the stator core 10 is formed by stacking the first core lamination 111 and the second core lamination 112 having different structures in a staggered manner, so that liquid can flow in the flow channel formed between the first core lamination 111 and the housing 20 and between the second core lamination 112 and the housing 20 in a series manner, and further the heat of the stator core 10 can be taken away by the cooling liquid, thereby achieving the cooling purpose, because the flow channel in this embodiment runs through the first core lamination 111 and the second core lamination 112, the heat dissipation capability of the motor 100 in this embodiment is strong.
Since the flow in this embodiment is directly formed between the outer surface of the stator core 10 and the stator core, the heat exchange area is greatly increased
As a specific embodiment of the present invention, as shown in fig. 3 to 4, a plurality of convex portions 113 and a plurality of concave portions 114 are distributed at intervals on the outer circumferential surface of the first core segment 111 of the present embodiment. The outer peripheral surface of the second core segment 112 is a smooth structure (as shown in fig. 5-6). The flow channel is formed between the concave portion 114 of the first core sheet 111 and the outer periphery of the second core sheet 112 and the inner wall of the housing 20. Specifically, the structures of the convex portion 113 and the concave portion 114 at the outer periphery of the first core segment 111 of the present embodiment can be freely designed according to actual needs. For example, the convex portion 113 in the present embodiment has a cubic shape. In other embodiments, the structure of the protrusion 113 may be a trapezoidal or other three-dimensional structure. The projection 113 may be formed in a flat shape only at the outermost portion. The outermost portions of the protrusions 113 of the first core stamped pieces 111 are in contact with the inner wall of the housing 20. The structural design of the periphery of the first iron core punching sheet 111 in this embodiment can greatly improve the heat exchange area, thereby improving the heat exchange effect.
In addition, the structure of the outer periphery of the second core stamped piece 112 of the present embodiment may be other than a smooth structure, and it is only necessary that the structural height at the outer periphery of the second core stamped piece 112 does not exceed the height of the convex portion 113 of the first core stamped piece 111, and a communicating flow channel can be formed between the second core stamped piece 112 and the concave portion 114 and the housing 20. When the outer periphery of the second core segment 112 is designed to have another structure, it is necessary to have a structure different from that of the first core segment 111. The periphery of the second core sheet 112 is designed to be of other structures, and compared with the other structures, the structure of the second core sheet is smooth, so that the heat exchange area can be increased, and further the heat exchange efficiency of the motor 100 is improved.
As other embodiments, the thickness of the first core stamped piece 111 and the thickness of the second core stamped piece 112 may be freely designed according to actual needs.
As another embodiment, in the present embodiment, when the first core segment 111 and the second core segment 112 are stacked at intervals, the outer circumferential surface of the second core segment 112 and the recess 114 are on the same plane. That is, the concave portion 114 of the first core sheet 111 and the periphery of the second core sheet 112 are in the same plane, so that the cooling liquid can smoothly flow between the first core sheet 111 and the second core sheet 112 in series, thereby improving the cooling efficiency.
As a specific embodiment of the present invention, a first protrusion 115 is further disposed at the concave portion 114 on the outer circumferential surface of the first core stamped sheet 111, and the first protrusion 115 extends along the axial direction of the first core stamped sheet 111. A second protrusion 116 is disposed on the outer peripheral surface of the second core sheet 112, and the second protrusion 116 extends along the axial direction of the second core sheet 112. When the first core punching sheet 111 and the second core punching sheet 112 are stacked at intervals, the first protrusion 115 and the second protrusion 116 are arranged in a matching manner. In this embodiment, the first protrusion 115 and the second protrusion 116 are designed to be accurately positioned when the first core lamination 111 and the second core lamination 112 are stacked.

The thickness of the core sheet 11, the number and size of the convex portions 101 and the concave portions 102 in this embodiment can be designed according to actual needs. Preferably, the greater the number of the convex portions 101 and the concave portions 102, the greater the number of the flow passages, the better the cooling effect.
