SEGMENTED-COIL MANUFACTURING METHOD, SEGMENTED-COIL MANUFACTURING DEVICE, AND SEGMENTED COIL MANUFACTURED USING SEGMENTED-COIL MANUFACTURING DEVICE

摘要

A segmented-coil manufacturing method is configured so that, in order to reduce the number of segmented-coil manufacturing steps, the method manufactures a segmented coil (SC) by winding a flat rectangular conductor (D) and using forming dies, the segmented coil (SC) having a circular arc section (Sa1), a crank section (S4), and a protrusion-shaped section (S5). The forming die includes an outer peripheral surface forming upper die (M1), an inner peripheral surface forming upper die (M4), an inner peripheral surface forming lower die (M2), and an outer peripheral surface forming lower die (M3). The circular arc section (Sa1), the crank section (S4), and the protrusion-shaped section (S5) are formed while at least two surfaces of the outer peripheral surfaces of the flat rectangular conductor (D) are restrained by the outer peripheral surface forming upper die (M1), the inner peripheral surface forming upper die (M4), the inner peripheral surface forming lower die (M2), and the outer peripheral surface forming lower die (M3).
