Abstract:
An electric motor comprising:a plurality of stator coils wound around a magnetic pole of a stator core, and of which lead wires are led to an external diameter side in the vicinity of one end of the stator core; a connecting conductor holder being an insulating annular member having a through hole at the central part, in which a plurality of accommodating grooves opened to one side and formed in belt shape in circumferential direction are provided in diameter direction so as to be located in close proximity to the lead wires of said stator coils; a first connecting conductor and a second connecting conductor each comprising a belt-like conductor accommodated in said accommodating grooves of said connecting conductor holder, and connecting terminals provided projecting from said belt-like conductor to the external diameter side of said connecting conductor holder and each connected to a predetermined lead wire of said stator coils; wherein the lead wires of said stator coils of same phase are connected to each other through said first connecting conductor, and the lead wires to be connected to an electrically neutral point of said stator coils are connected through said second connecting conductor; and a plurality of said first connecting conductors are provided, each having a cross-sectional area sized to make electric resistance of each phase equal after connecting the lead wires of said stator coils.
