Abstract
Official abstract text for this publication.
The present invention is concerning a controller-integrated rotary electric machine having a power circuit portion provided between an external power source and a stator winding of a rotary electric machine main body, wherein the power circuit portion includes: a positive-side power input/output terminal and a negative-side power input/output terminal that are electrically connected to the external power source; a power module that performs power conversion between the external power source and the stator winding; and a single heat sink that cools the power module, the positive-side power input/output terminal being fixed to the single heat sink via an insulating material, and the negative-side power input/output terminal being fixed directly to the single heat sink.
First claim
Opening claim text (preview).
What is claimed is: 1 . A controller-integrated rotary electric machine having a power circuit portion provided between an external power source and a stator winding of a rotary electric machine main body, wherein the power circuit portion includes: a positive-side power input/output terminal and a negative-side power input/output terminal that are electrically connected to the external power source; a power module that is connected to the external power source by the positive-side power input/output terminal and the negative-side power input/output terminal, is also connected to the stator winding, and performs power conversion between the external power source and the stator winding; and a single heat sink that cools the power module, the positive-side power input/output terminal being fixed to the single heat sink via an insulating material, and the negative-side power input/output terminal being fixed directly to the single heat sink. 2 . The controller-integrated rotary electric machine according to claim 1 , wherein the positive-side power input/output terminal and the negative-side power input/output terminal are placed separately from each other with a space portion therebetween. 3 . The controller-integrated rotary electric machine according to claim 2 , wherein a seating surface position for a harness mount of the positive-side power input/output terminal and a seating surface position for a harness mount of the negative-side power input/output terminal are separated from each other in an axial direction with the space portion therebetween. 4 . The controller-integrated rotary electric machine according to claim 2 , wherein a seating surface position for a harness mount of the positive-side power input/output terminal and a seating surface position for a harness mount of the negative-side power input/output terminal are separated from each other in a radial direction with the space portion therebetween. 5 . The controller-integrated rotary electric machine according to claim 2 , wherein either one of the positive-side power input/output terminal and the negative-side power input/output terminal extends in an axial direction of the rotary electric machine, and the other one of the positive-side power input/output terminal and the negative-side power input/output terminal extends in a radial direction of the rotary electric machine. 6 . The controller-integrated rotary electric machine according to claim 1 , wherein either one of the positive-side power input/output terminal and the negative-side power input/output terminal is attached to a harness mount provided with an even number of depressions arranged at approximately equal intervals, and the other one of the terminals is attached to a harness mount provided with an odd number of depressions arranged at approximately equal intervals. 7 . The controller-integrated rotary electric machine according to claim 2 , wherein either one of the positive-side power input/output terminal and the negative-side power input/output terminal is attached to a harness mount provided with an even number of depressions arranged at approximately equal intervals, and the other one of the terminals is attached to a harness mount provided with an odd number of depressions arranged at approximately equal intervals. 8 . The controller-integrated rotary electric machine according to claim 3 , wherein either one of the positive-side power input/output terminal and the negative-side power input/output terminal is attached to a harness mount provided with an even number of depressions arranged at approximately equal intervals, and the other one of the terminals is attached to a harness mount provided with an odd number of depressions arranged at approximately equal intervals. 9 . The controller-integrated rotary electric machine according to claim 4 , wherein either one of the positive-side power input/output terminal and the negative-side power input/output terminal is attached to a harness mount provided with an even number of depressions arranged at approximately equal intervals, and the other one of the terminals is attached to a harness mount provided with an odd number of depressions arranged at approximately equal intervals. 10 . The controller-integrated rotary electric machine according to claim 5 , wherein either one of the positive-side power input/output terminal and the negative-side power input/output terminal is attached to a harness mount provided with an even number of depressions arranged at approximately equal intervals, and the other one of the terminals is attached to a harness mount provided with an odd number of depressions arranged at approximately equal intervals.
