Abstract
A rotating electric machine includes a stator and a rotor. The stator includes a stator core and a stator winding that includes phase coils wound around slots of the stator core. Each phase coil is configured such that: a first end is connected to an external terminal; a second end is connected to a neutral point; and 2n (n being a natural number) circling coils are arranged to circle the stator core and connected in series. A neutral-point-side coil is housed in a first slot where a terminal-side coil is housed. The terminal-side coil is a circling coil that is arranged on the external-terminal side of a first phase coil among the phase coils. The neutral-point-side coil is a circling coil that is arranged on the neutral-point side of a second phase coil among the phase coils. The second phase coil is different in phase from the first phase coil.
