Stator of electrical machine

摘要

A stator (1) of a rotary electrical machine includes a core unit (3) configured by a plurality of core assemblies (4), around which wires are respectively wound to form the coils (42), including low voltage side terminals (44), which connect first ends (422) of the coils (42), and a bus ring (5) attached to the core unit (3) so as to connect second ends (421) of the coils (42) to electricity supply wires (53u, 53v, 53w) by high voltage side terminals (54). Each terminal accommodating portion (6) is individually formed relative to each of the core assemblies (4) at an external side of the coils (42). Each of the terminal accommodating portions (6) is filled with an insulating resin material in a state where at least one of a connecting portion of the first end (422) and each of the low voltage side terminals (44) and a connecting portion of the second end (421) and each of the high voltage side terminals (54) is accommodated within each of the terminal accommodating portions (6).
