Abstract
A rotary electrical machine includes a housing which includes a flow passage portion in which a refrigerant flow passage through which a refrigerant flows is formed and which houses a rotor and a stator. The refrigerant flow passage includes a first flow passage of which a length from the inlet to the outlet in the circumferential direction is a predetermined length, and a second flow passage of which a length from the inlet to the outlet in the circumferential direction is shorter than that of the first flow passage. The second flow passage is provided with a partition wall portion between the inner peripheral wall and the outer peripheral wall in the radial direction. A slit penetrating the partition wall portion in the circumferential direction is formed in the partition wall portion. A width of the slit is smaller than a width of the first flow passage.
