Rotating electric machine

A rotating electric machine comprising a stator,

• the stator including:
• a stator core having an annular shape, which has a plurality of slots formed in a circumferential direction of the stator core;
• and
• a stator winding mounted to the stator core,
• wherein the stator winding includes a plurality of coils formed by distributed winding, each being made of a conductor that is insulation-coated,
• wherein each of the plurality of coils includes:
• 2X (X is a natural number equal to or larger than 1) slot insertion portions inserted into the slots;
• (2X-1) turn portions configured to connect the 2X slot insertion portions alternately on one axial end side and another axial end side of the stator core to continuously couple the 2X slot insertion portions;
• radially inner-side terminals, each extending from the slot insertion portion located at one end of the continuously coupled slot insertion portions;
• and
• radially outer-side terminals, each extending from the slot insertion portion located at another end of the continuously coupled slot insertion portions,
• wherein the radially inner-side terminals extend from radially innermost positions in the slots in a one-by-one manner,
• wherein the radially outer-side terminals extend from radially outermost positions in the slots in a one-by-one manner,
• wherein the 2X slot insertion portions are respectively inserted into the slots so as to be arranged in one row in a radial direction of the stator core,
• wherein a first terminal and a second terminal extend from two of the slots, which are separate from each other in the circumferential direction, and a third terminal extends from one of the slots, which is located between the two slots, the first terminal, the second terminal, and the third terminal each being any one of the radially inner-side terminal and the radially outer-side terminal,
• wherein the first terminal and the second terminal are connected to each other with use of a bus bar;
• and
• wherein the bus bar has:
• a first end portion to be connected to a distal end portion of the first terminal;
• a second end portion to be connected to a distal end portion of the second terminal;
• and
• an interconnecting portion configured to couple the first end portion and the second end portion to each other, which is arranged in the circumferential direction on the stator core side of the first end portion and the second end portion so as to pass on the slot side of the third terminal.
