A three-phase rotary electrical machine including a stator (1) including a stator core (10) including split cores (11), a rotor (2), a bobbin (30, 40) attached to each of the split cores, a winding (20) being wound around each split core to which the bobbin is attached, and a bobbin unit (50, 60) including three of the bobbins which are arranged in a circumferential direction of a rotation axis (X) as one unit, wherein the bobbin positioned at a center of the bobbin unit are formed in a bendable manner integrally with the bobbins positioned adjoining to the bobbin positioned at the center, the bobbin unit is sealed with the bobbin unit positioned adjoining thereto, and a cooling passage (71) extending in the axial direction is provided at each clearance between the windings for three phases. |
