摘要： To provide a rotary electric machine can suppress from enlarging the outer diameter of the rotary electric machine due to mounting of the power module and the heatsink. In a rotary electric machine (100), the heatsink fixing face (16) of the power module (160) extends in the radial direction (Y) and the axial direction (Z); and the two or more power modules (160) are provided; the two power modules (160) are arranged so that the heatsink fixing faces (16) thereof face each other in a circumferential direction (X); and, between the two power modules (160), one or more heatsinks (110) is disposed, and a passage (180) through which a refrigerant flows to the radial direction (Y) is formed.

摘要： There is provided a motor generator that makes it possible that even when a nut for fastening a pulley to a rotation axle loosens, the pulley is prevented from falling out of the rotation axle. In a motor generator (1), while being fit to the outer circumferential surface of the one end of a rotation axle (11), a pulley (12) is fastened to the rotation axle (11) with a nut (14) screwed to a male screw portion (11b) provided in the outer circumferential surface of the rotation axle (11) at the axial-direction one side (X1) of the fitting portion of the pulley (12), and on a portion of the rotation axle (11) at the axial-direction one side (X1) of the nut (14), there is mounted a pulley falling prevention member (9) that prevents the pulley (12) from falling out of the rotation axle (11) when the nut (14) loosens.

摘要： To provide a rotary electric machine can suppress from enlarging the outer diameter of the rotary electric machine due to mounting of the power module and the heatsink. A rotary electric machine (100) is provided with a power module (160) that is provided with a power semiconductor device (166H, 166L) which turns on and off energization to the windings (32); a heatsink (110) that is thermally connected to a heat sink fixing face (16) of the power module (160); and a refrigerant passage (160) through which a refrigerant flows in an arrangement space of the heatsink (110), wherein the heatsink fixing face (16) of the power module (160) extends in the radial direction (Y) and in the axial direction (Z), and wherein in the refrigerant passage (180), the refrigerant flows in the radial direction (Y) in the arrangement space of the heatsink (110).
