Abstract

In one aspect of a motor of the present invention, an inverter housing portion is located on the radially outer side of a stator housing portion. A housing has a tubular circumferential wall surrounding the rotor and the stator on the radially outer side of the rotor and the stator, and is a single member. The circumferential wall has a first cooling flow path, and a partition wall that partitions the stator housing portion and the inverter housing portion. The first cooling flow path extends in the circumferential direction, and at least a part of the first cooling flow path is provided in the partition wall. As viewed along the predetermined direction, a portion of the first cooling flow path provided in the partition wall has a portion overlapping the inverter and a portion overlapping the capacitor.
