Problems solved by technology
[0003] However, in the technology disclosed in the aforementioned patent documents, the distance between adjacent terminal layers in the peripheral direction is relatively narrow, and when soldering, due to the splash (splash) flow of solder, the adjacent connected terminal layers may be short-circuited.
[0004] Therefore, when the terminal layer is connected by resistance welding, the solder defect will be eliminated, but when the welding rod is pressed, the terminal of the terminal layer will deviate, and the pressure of the welding rod will also cause the expansion of the terminal area (the terminal becomes thicker). Short circuit between adjacent terminal layers due to metal flying
Furthermore, during resistance welding, since the current applied to the resistance layer passes through the Freming force, due to the deviation of the terminal, the terminal layer will touch the adjacent another terminal layer and cause a short circuit

Embodiment Construction
[0019] Below, refer to the attached Figure 1 to Figure 5 , the first embodiment of the present invention will be described in detail. First, a manufacturing apparatus for a coil substrate and a coreless motor in this embodiment will be described. In addition, the coreless electric motor involved in this embodiment is adopted as a rotor of a generator.
[0020] Such as figure 2 As shown, on the coil substrate 1, a plurality of conductive strips 3 are arranged at certain intervals. The respective terminals 5 of the respective conductive strips are connected by side edge portions 7 . The coil base 1 forms conductive strips 3 at certain intervals after being etched on a copper plate and stamped.
[0021] figure 1 and image 3 As shown, both ends of the coil base 1 are wound into a cylindrical shape between cylindrical coil jigs 9a and 9b, and are concentrically wound into multiple layers. Between each coil base body 1, insert insulating resin material 13 (refer to image...

A method for manufacturing a coreless armature, which can prevent a short circuit of adjacent terminal layers when resistance-welding the terminal layers, is provided. In a method for manufacturing a coreless armature, terminals 5 of the conducting bands 3 provided to each coil base 1 are stacked to form a terminal layer 23, a welding rod 21 is pressed against a terminal positioned on an outermost periphery so as to interpose the terminal layer 23 between coil jigs 9a and 9b and the welding rod 21, and an electric current is applied thereto, thereby connecting each terminal 5 of the terminal layer 23 by way of resistance welding, in which an insulating material 25 is arranged between terminal layers 23 adjacent in a circumferential direction to resistance-weld the terminal layers 23.
Description
technical field [0001] The present invention is a manufacturing method of a coreless motor used as a rotor of a generator and a motor. Background technique [0002] In the patent document with the publication number JP2002-542749, it is disclosed that a plurality of conductive strips are arranged side by side to form a coil substrate, and after the intervening insulating layer is arranged in a concentric circle, the conductive strip terminals set in each coil substrate are overlapped. Terminal layers are formed, and the terminal layers arranged at regular intervals in the peripheral direction are connected by sequential welding and resistance welding. [0003] However, in the technology disclosed in the aforementioned patent documents, the distance between adjacent terminal layers in the peripheral direction is relatively narrow, and the adjacent connected terminal layers may be short-circuited due to the splash (splash) flow of solder during soldering. [0004] Therefore, ...
