Abstract

máquina giratória elétrica, e, método de fabricar os segmentos de condutor elétrico. em uma máquina giratória elétrica (1), um estator (2) inclui um núcleo de estator cilíndrico oco (7) e uma bobina de estator (8) montada no núcleo de estator (7). a bobina de estator (8) tem uma pluralidade de porções em ranhura (25), cada uma das quais é recebida em uma ranhura correspondente (11) do núcleo de estator (7), e uma pluralidade de porções de conexão (26), cada uma das quais está localizada fora das ranhuras (11) do núcleo de estator (7) para conectar um par correspondente das porções em ranhura (25). ademais, para cada uma das porções de conexão (26), pelo menos parte da porção de conexão (26) é formada de um fio elétrico deformado que é obtido achatando um fio elétrico redondo. o fio elétrico deformado tem um par oposto de faces laterais planas (15) que são paralelas entre si e um par oposto de faces laterais curvadas (17) que são convexas em direções opostas.electrical rotating machine, and, method of manufacturing the electrical conductor segments. in an electrical rotating machine (1), a stator (2) includes a hollow cylindrical stator core (7) and a stator coil (8) mounted on the stator core (7). the stator coil (8) has a plurality of slotted portions (25), each of which is received in a corresponding slot (11) of the stator core (7), and a plurality of connecting portions (26), each of which is located outside the slots (11) of the stator core (7) to connect a corresponding pair of the slotted portions (25). Furthermore, for each of the connecting portions (26), at least part of the connecting portion (26) is formed from a deformed electrical wire that is obtained by flattening a round electrical wire. The deformed electrical wire has an opposing pair of flat side faces (15) that are parallel to each other and an opposing pair of curved side faces (17) that are convex in opposite directions.
