ROTARY ELECTRIC MACHINE

摘要

A rotary electric machine includes a three-phase coil including a first phase coil, a second phase coil, and a third phase coil for magnetic flux generation. A bridge conductor connecting an ath end and a bth end of the first phase coil, and a bridge conductor connecting the ath end and the bth end of the third phase coil are provided in a protruding shape on one side of a stator in a radial direction when viewed in a axial direction of the stator. A bridge conductor connecting the ath end and the bth end of the second phase coil is provided in a protruding shape on the other side of the stator in the radial direction when viewed in the axial direction of the stator. The bridge conductor of each coil in the three-phase coil is arranged at the same height position in the axial direction.
