摘要:
There is provided a rotating electric machine capable of preventing a coolant from being retained at an outer surface of a rotor. This rotating electric machine includes a rotation shaft provided so as to be rotatable, a core body secured to the rotation shaft, a permanent magnet embedded in the core body, and an end plate provided so as to be opposed to an axial end surface of the core body. A first coolant channel is formed in the rotation shaft to allow a coolant to flow therethrough. A second coolant channel is formed between the end plate and the axial end surface of the core body to communicate with the first coolant channel. A partition wall that partitions the second coolant channel in a circumferential direction and a path wall that guides the coolant in the second coolant channel toward an outer peripheral edge region of the axial end surface where the permanent magnet is placed are formed inside the second coolant channel.

A connection line has a first bent portion bent toward a coil's main body in a vicinity of a stator core's axial length limit line. Furthermore, the connection line at a portion closer to the coil's main body than the first bent portion has a second bent portion bent away from the coil's main body. Furthermore, the connection line has a third bent portion bent away from the coil's main body to have a connection portion along an end surface of the terminal member in contact therewith generally parallel thereto.

A semiconductor device and a method of producing the same, wherein a joining member and a joined member are bonded by means of brazing in a way such that no voids are left inside the joining layer. The semiconductor device comprises a joined member and a joining member which is joined to the joined member by means of brazing. The joined member is provided with a through hole which is open on the joining surface with the joining member, and a path communicating with the through hole is provided on at least one of the joining surface of the joining member with the joined member or the joining surface of the member with the joining member.

A rotating electric machine, comprising a stator, a rotor, a case storing the stator and the rotor, and an oil pump. Oil discharge ports are formed at the terminal part of an oil discharge passage of the case, and a cooling oil is supplied to the upper cutout parts of the stator. A groove part is covered by a cover to form a closed flow passage. Since the cooling oil is sufficiently applied to the portion of a coil exposed to the inside of the flow passage, a cooling efficiency is increased. Also the cooling oil is guided to an orifice on the lower side in the gravitational direction. Accordingly, since the cooling oil does not flow in an air gap between the rotor and the stator, a power loss can be prevented from occurring.

An in-wheel motor includes a motor, a shaft, an oil pump and oil paths. The oil pump is provided on one end of the shaft. The motor includes a stator core, stator coils and a rotor. The oil pump pumps up an oil from an oil reservoir via an oil path to supply the pumped-up oil to another oil path. The another oil path supplies the oil from the oil pump to the outer periphery of the stator core of the motor from an opening end.

A stator includes a stator core having a plurality of slots in a direction parallel to the rotating shaft of a rotating electrical machine; and a coil plate laminated body formed by laminating a plurality of I-shaped coil plates, each of which has an insulating film adhered at least on one side, in a diameter direction. In the coil plate laminated body, a plurality of coil plates are inserted inside a resin insulator inserted into the slots so that the insulating film is arranged between the coil plates, and the coil plates are integrally held by the resin insulator. The resin insulator integrally holds the coil plate laminated body of a plurality of phases in the same slot.
