Tool for holdling coil for electromechanical device for converting electrical energy and mechanical energy

Abstract

The present invention was contrived through attention being focused on the following in a prior-art distributed-winding coil: a 'solenoid' configuration in which winding wires are to be wound is preserved when initially formed, but this configuration tends to be loosened during subsequent steps, and the initial winding sequence of the winding wires, or the position of the winding wires relative to each other, tends to be disrupted, and accordingly must be prevented, when a certain force is applied and the necessary bending or deformation is induced in coils with distributed winding in which the solenoid configuration is preserved, or when the coils are ultimately inserted into slots. Therefore, as a solution, the present invention provides a holding toolprovided with: at least two substrateslinked at one end so as to be able to open and close; an outletformed at the other end of the substrates; and a holding spacecapable of opening on the outletside, and holding the first accommodation portionor the second accommodation portionof a coilwhile maintaining the alignment state of the winding wiresA that constitute part of the first accommodation portionand the second accommodation portionwhen the substratesare closed; the holding toolbeing capable of forming a twist portion at a first coil end and a second coil end and reducing the size of the coil ends of the coils while maintaining the alignability of the winding wires that constitute part of the first and second accommodation portions of the coil
