Abstract: In a rotary electric machine, wound wires are connected to a first terminal and a second terminal. Circuit terminals that are configured from a conductive metal other than aluminum, and the first terminal and the second terminal that are configured from a metal with a principal component of aluminum are joined together inside a circuit chamber that has high water resistant properties. Corrosion is accordingly suppressed at join sites of the circuit terminals with the first terminal and the second terminal. There is therefore no need to coat the join sites with for example a sealing material in order to suppress corrosion at the join sites. Good electrical continuity is accordingly enabled between the circuit terminals and the wound wires while suppressing an increase in costs, even when the wound wire is configured from a metal with a principal component of aluminum.

Abstract: A rotor includes magnetic pole portions and first and second ferric core portions. The first and second ferric core portions are each located between magnetic pole portions in the circumferential direction of a rotor. A first gap is formed between the first or second ferric core portion and a magnetic pole portion at a first circumferential side. A second gap is formed between the first or second ferric core portion and the magnetic pole portion at a second circumferential side. The first gap has a smaller width than the second gap at the first ferric core portion. The first ferric core portion is inclined toward the first circumferential side. The first gap is larger than the second gap at the second ferric core portion. The second ferric core portion is inclined toward the second circumferential side.
