Problems solved by technology

[0004] However, since the above-mentioned flexible base plate 91 of the conventional motor stator is made of flexible materials, it tends to have inherent defects in materials such as insufficient rigidity and poor bonding stability.
In addition, since any two carrier plates 911 are connected by a bridging portion 912, when the installation space of the motor stator is to be compressed, it is necessary to bend the bridging portion 912 to have only a very small curvature, which is easy to cause the bridging portion 912 Broken and damaged; moreover, after forming the motor stator, bending the bridging portion 912 protruding from the side of each carrier plate 911 will also increase the installation space of the motor stator
In addition, the winding group 92 can only be distributed on the two opposite surfaces of the flexible substrate 91 at most, resulting in extremely complicated wiring patterns of the winding group 92, which will reduce the production yield of the motor stator.

Abstract

A motor stator comprising a plurality of wiring layers (1) and at least one electrical connection module (2) is disclosed. Each wiring layer (1) has an insulating base (11) and at least one winding module (14) formed on the insulating base (11). Each electrical connection module (2) has a thorough conductor (21) and at least one local conductor (22), with the thorough conductor (21) penetrating the plurality of wiring layers (1) and electrically connecting with at least one of the at least one winding module (14) of at least one of the plural wiring layers (1), with the at least one local conductor (22) penetrating at least one of the plural wiring layers (1), and with each local conductor (22) electrically connecting the winding modules (14) of at least two of the plural wiring layers (1).

Description

technical field [0001] The present invention relates to a motor stator, in particular to a motor stator with multi-layer boards having an electrical connection module penetrating through several wiring layers to reduce wiring complexity. Background technique [0002] In view of the miniaturization trend of today's electronic products, fans installed in various miniaturized electronic products for driving wind and dissipating heat must also occupy a smaller installation space than traditional fans. Therefore, in the design and mass production of fan miniaturization, how to manufacture a motor stator with high power and good structural strength has become one of the key elements of fan miniaturization technology. In detail, since it is difficult to meet the "light" and "thin" requirements of micro fans with the motor stator formed by traditional winding methods, the existing motor stator manufacturing technology uses printed circuit board layout (PCB layout) or electroforming ...
