After melted enamel coating is discharged, a fusion process of electrical wire-to-wire connection is carried out inside a crimping connector. In the conductor connection method based on the fusion process, a plurality of enamel-coated conductor wires are inserted in the crimping connector prior to the start of the fusion process. Further, a temporary crimping process that provides the crimping connector a temporary crimping by mechanical pressurizing means is also performed. Addition of force at both end parts or either end part of the cross-section orthogonal to the axis of the above crimping connector may cause expansion, which needs to be suppressed with external force. At the same time, the cross-sectional areas corresponding to both end parts or either end part should preferably be as small as possible. The temporary crimping is applied to the crimping connector for this purpose.

Conductor wire connecting method

A rotating electrical machine includes: a stator that has a stator core and a stator coil; and a rotor disposed rotatably on an inner circumferential side of the stator core. The stator core includes a plurality of slots opening on the inner circumferential side and the slots are each formed as an open slot with a width of an inner circumferential-side opening thereof ranging along a circumferential direction set substantially equal to or greater than a width of a bottom side measured along the circumferential direction. The stator further includes a slot insulator disposed between inner wall of each of the slots at the stator core and the stator coil and a holding member constituted with a nonmagnetic material and inserted in each of the slots at the stator core so as to hold the slot insulator between two side surfaces present along the circumferential direction at the slot. The stator is formed by winding the stator coil through the plurality of slots.

Rotating electrical machine and method for manufacturing the same

After melted enamel coating is discharged from the crimping connectors, electrical wire-to-wire connection, that is, the fusion process, is carried out inside the crimping connector. In this conductor connection method based on the fusion process, plural the above enamel-coated conductor wires are inserted in the above crimping connector prior to the start of the fusion process. Further, the temporary crimping process which provides the crimping connector a temporary crimping by mechanical pressurizing means is also a part of entire process. Addition of force at both the end parts or either one of them of the cross-section orthogonal to the axis of the above crimping connector may cause expansion, which needs to be suppressed with external fore. At the same time, the areas of cross-section corresponding to both the end parts or either of them mentioned above should preferably be held as small as possible. The above temporary crimping is applied to the above crimping connector for this purpose.

Conductor wire connecting method, and connecting terminal, stator, and rotary electric machine

The present invention relates to a manufacturing system which accepts a custom order of product from a customer and custom manufactures a product without sacrificing manufacturing efficiency. The manufacturing system includes the featuring steps of inputting the required specification of a product, creating the product design based on the design information of the product transmitted from a designing department, status data from the production department, and the input required specification, showing the created product design to the customer, selectively indicating a product to be purchased, transmitting the specification of the selected product to the production department, and producing a product based on the selected product specification.
