摘要： A coil (20) is formed by winding a conductive wire. A core (30) houses the coil (20). The core (30) is provided with a refrigerant inlet (61) and a refrigerant outlet (62). A refrigerant flow path (65) connecting the refrigerant inlet (61) and the refrigerant outlet (62) is provided between the coil (20) and the core (30). The refrigerant flow path (65) is formed so that a refrigerant flowing from the refrigerant inlet (61) to the refrigerant outlet (62) mainly flows along the coil (20) in a winding direction of the coil (20).

摘要： In a stator (3), a segment conductor (18) includes a pair of leg portions (20) inserted into slots (15), and a crossover wire portion (21) that couples the pair of leg portions (20). The stator (3) includes an insulator (11a) that includes a winding barrel portion (23) and an insertion portion (26) that are integrally molded. The winding barrel portion (23) is disposed between a stator core (9) and the crossover wire portion (21) of the segment conductor (18). The insertion portion (26) is disposed on an inner side from the leg portions (20) of the segment conductor (18) inside the slots (15) of the stator core (9).

摘要： A rotor (30) has magnetic poles (34) each including a rotor core (31) having two or more through holes (32) arranged side by side in a circumferential direction of the rotor, and a permanent magnet (35) inserted into each of the through holes (32). A length of a portion of the rotor core in a radial direction of the rotor between an inner surface of each of the through holes (32) close to an outer periphery of the rotor and an outer peripheral surface of the rotor (30) is shorter than a length of each permanent magnet (35) in the radial direction of the rotor. A magnetic circuit in which the permanent magnets (35) generate a magnetic flux shows a smaller magnetic resistance in a portion of the rotor radially outward of the permanent magnets (35) than in a portion of the rotor radially inward of the permanent magnets (35).
