Abstract:
An electric rotating machine comprising a stator, a rotor core which can rotate inside said stator with a clearance between the rotor core and the inner surface of the stator, a stator winding formed around said rotor core, and a rotor having feeding lead wires connected to said rotor winding by means of a joint conductor;wherein said feeding lead wire comprises a first part connected to said joint conductor, a second part thinner than said first part, and a third part which is formed between said first and second parts and has a thickness changing from the thickness of said first part to the thickness of the second part; and wherein a size of a connecting plane of said joint conductor to said first part of said feeding leading wire and a size of a connecting plane of said first part of said feeding leading wire to said joint conductor are substantially the same.
