Description
Technical Field
[0001] The utility model relates to the technical field of motors, in particular to a stator core monomer winding placement frame structure. Background Art
[0002] In the production of stator core assemblies, an insulating frame (insulating frame) is required at each end of the core, and then the enameled wire is wound. In the production of stator core assemblies, an insulating frame (insulating frame) is required at each end of the core, and then the enameled wire is wound. The single wound cores are assembled into a whole circle to form the stator core.
[0003] In the prior art, the insulating frames at both ends need to form an insulating structure that penetrates the iron core. Therefore, for stator cores of different thicknesses, insulating frames of different lengths must be matched. The insulating frames must be produced by molds. The mold cost of the insulating frames is relatively high, and the investment is large, which increases the production cost. In addition, the thicker the stator core is, the longer the part where the insulating frame and the core match. If the insulating frame is found to be incompatible during winding, it is easy to cause scrapping, which is not only wasteful but also reduces production efficiency.
[0004] China Patent Authorization Announcement Number: CN 207947663 U, Authorization Announcement Date: October 9, 2018. This utility model relates to a measuring frame for assembling turbine runner blades, including a pad, a positioning flange, a base, a rotating cylinder, a buttress and a measuring arm, wherein the outer edge of the positioning flange matches the tail cone hole of the runner upper crown and is concentric with the tail cone hole, the outer circle of the base matches the inner circle of the positioning flange and is concentric with the positioning flange, the rotating cylinder is welded to the base and is concentric with the base, the base and the positioning flange are connected by bolts, the measuring arm is installed on the rotating cylinder, the buttress supports the runner lower ring, and the pad supports the runner upper crown. The shortcomings of this technical solution are: replacing different lengths of insulating paper according to different thicknesses of stator cores increases the number of structural monomers, and at the same time the support stability is insufficient, and the insufficient adaptability of the adjustment method reduces the adjustment flexibility.
