Abstract
A rotating electrical machine includes: a three-phase coil including a U-phase coil, a V-phase coil, and a W-phase coil each formed of a flat wire; a neutral point bus bar forming a neutral point of the three-phase coil and formed of a conductive plate; and a temperature detector configured to detect a temperature of the three-phase coil. The neutral point bus bar is formed in an arc shape along an outer periphery of the three-phase coil. One end of one coil in the three-phase coil is connected to a vicinity of a center of the neutral point bus bar in a circumferential direction thereof. One end of each of remaining two coils in the three-phase coil is connected to a vicinity of an end of the neutral point bus bar in the circumferential direction.
