Abstract: A rotating electric machine includes a rotating shaft with a rotation axis, a rotor, a stator, a housing, a plurality of control modules and a cover. The housing rotatably supports the rotating shaft and accommodates the rotor and the stator. The housing has a shaft-supporting part that supports an end portion of the rotating shaft. The control modules are arranged outside the shaft-supporting part of the housing and around the rotating shaft. The control modules each include a plurality of switching elements and a heat sink provided only on the rotation axis side of the switching elements. The cover, which covers the control modules, has a bottom part arranged on an opposite side of the control modules to the shaft-supporting part of the housing. End surfaces of the heat sinks of the control modules are formed to extend along an inner wall surface of the bottom part of the cover.

Abstract: In a power converter, outer lead frames are drawn out from a semiconductor module and are bent to be separated from a cooler. Each of the outer leads has a terminal end. The terminal end of each outer lead frame projects from a virtual plane extending along a second surface of a housing. Connector leads each includes an inner portion disposed in the housing, and an outer portion drawn out from the housing and bent to be separated from the cooler. The outer portion of each connector lead has a terminal end. The terminal end of the outer portion of each connector lead projects from the virtual plane.

Abstract: A rotor for a rotating electric machine includes a rotor core having a plurality of magnet-receiving holes formed along a circumferential direction, and a plurality of permanent magnets each of which is received in a corresponding one of the magnet-receiving holes of the rotor core. Each of the magnet-receiving holes has a pair of a radially-outer wall surface and a radially-inner wall surface that are radially opposite to each other. Each of the permanent magnets is fixed in the corresponding magnet-receiving hole of the rotor core by a fixing resin that includes a radially outer resin interposed between the permanent magnet and the radially-outer wall surface of the corresponding magnet-receiving hole and a radially inner resin interposed between the permanent magnet and the radially-inner wall surface of the corresponding magnet-receiving hole. An adhesive strength of the radially outer resin is higher than an adhesive strength of the radially inner resin.

Abstract: A rotating electric machine includes a rotating shaft, a rotor, a stator, a housing, control modules and fixing members. The housing, which is grounded, rotatably supports the rotating shaft and accommodates the rotor and the stator.The control modules are arranged around the rotating shaft and adjacent to one another. Each of the control modules includes switching elements, a supporting part that supports the switching elements, and at least one connection part having a ground terminal formed therein. The fixing members are provided to fix the connection parts of the control modules to the housing. Each adjacent pair of the connection parts respectively belonging to two different ones of the control modules are together fixed to the housing by a corresponding one of the fixing members; the ground terminals formed in the adjacent pair of the connection parts are together electrically connected to the housing.

Abstract: A rotating electric machine includes a rotor, a stator, a housing, a plurality of control modules and a joining member. The stator includes a stator coil. The housing accommodates both the rotor and the stator therein. The control modules are capable of supplying multi-phase alternating current to the stator coil and rectifying multi-phase alternating current generated in the stator coil into direct current. The control modules include a first control module and a second control module that are arranged adjacent to each other. The first and second control modules are joined, by the joining member, to be in surface contact with each other.
