Patent ID: 8288903

Claim:
A stator of a rotary electric motor, comprising: a plurality of core segments arranged in an annular fashion; a plurality of coils wound around the core segments via bobbins; a plurality of terminals connected to the coils; and a plurality of terminal mounting members to which the terminals are mounted; wherein the bobbin and the terminal mounting member for each of the core segments are molded by resin and integrated with the corresponding core segment; connection wire retaining members each retaining a connection wire between the coils for each phase during winding of the coils, wherein each of the connection wire retaining members is molded by resin and integrated with the corresponding core segment; wherein each connection wire retaining member includes a first side wall portion, a second side wall portion and an outer wall portion, the first side wall portion and the second side wall portions being disposed at right and left end edges of the corresponding core segment with respect to a circumferential direction of an annular of the annular fashion, and the outer wall portion being disposed on an outer peripheral side of the annular; wherein a retention groove is formed in the outer wall portion and extends in the circumferential direction; wherein a first guide groove is defined between the first side wall portion and the outer wall portion, and a second groove is defined between the second side wall portion and the outer wall portion; wherein each of the first and second guide grooves has a groove bottom portion at substantially the same level as the retention groove; and wherein the connection wire extends along the first guide groove of one of a pair of the core segments for each phase, the retention groove of at least one of the core segments positioned between the pair of the core segments, and the second guide groove of the other of the pair of the core segments.
