First, an operation when generating a driving force for driving the vehicle will be described.
The negative terminal of the battery B is connected to the vehicle, and is connected to the connection portion 31k of the power supply wiring member 31b via the housing 20. When an ignition switch (not shown) of the vehicle is turned on, the positive terminal of the battery B is connected to the connection portion 31j of the power supply wiring member 31a via the terminal member 31t. As a result, direct current is supplied to the power supply terminals of the power modules 33A to 33C via the connection portions 31h and 31i of the power supply wiring members 31a and 31b. Further, a direct current is supplied to the wiring board 30 through the connection portions 31f and 31g of the power supply wiring members 31a and 31b, and is supplied to the rotation angle detection circuit IC32, the field circuit IC34, and the microcomputer 35 through the wiring pattern of the wiring board 30. Direct current is supplied.

When the direct current is supplied, the rotation angle detection circuit IC32, the field circuit IC34, and the microcomputer 35 start operation.
The rotation angle detection circuit IC 32 detects the rotation angle of the rotor 22 from the magnetic field generated by the rotation angle detection magnet 25.

  The microcomputer 35 uses the power modules 33A, 33B, 33C, and 33C based on the command input from the outside via the wiring pattern of the external communication wiring member 31e and the wiring board 30 and the detection result of the rotation angle detection circuit IC32.

  The wiring board 30 is connected to the connection part 31n of the rotor wiring member 31d. The connection part 31o of the rotor wiring member 31d is connected to the brush 24 via the wiring member 31s.

(charging)
Next, an operation when generating electric power for charging battery B will be described.
When the driving force is supplied from the engine, the stator windings 21b and 21c generate a three-phase alternating current. The microcomputer 35 stops switching of the switching elements of the power modules 33A, 33B, and 33C. The diodes of the power modules 33A, 33B, and 33C convert the three-phase alternating current supplied from the stator windings 21b and 21c through the wiring member 31r and the stator wiring member 31c into direct current, and supply the power wiring members 31a, 31b and The battery is supplied to the battery via the terminal member 31t.

(Judgment of state)
The control apparatus-integrated dynamoelectric machine 1 of this embodiment can determine the state based on detection signals from temperature detection elements 33Af, 33Bf, and 33Cf provided in the power modules 33A, 33B, and 33C.

Specifically, when charging and discharging are performed, electricity flows through the two sets of stator windings 21b and 21c. When the rotating electrical machine 1 is normal, the temperatures of the power modules 33A, 33B, and 33C do not exceed a predetermined temperature.
When there is an abnormality in the rotating electrical machine 1, the temperature of at least one of the power modules 33A, 33B, 33C rises and exceeds a predetermined temperature. When the temperature rises further beyond the predetermined temperature, or when the state exceeding the predetermined temperature continues for a long time, the electrical insulation of the stator windings 21b and 21c decreases, and the battery B is charged. This leads to a decrease in generated power.

  When an abnormality occurs in one of the two sets of stator windings 21b and 21c, the energization path of the stator winding (assumed to be the stator winding 21b) abnormally generates heat. Then, the temperature of the power modules 33A and 33B that control the stator winding 21b rises and exceeds a predetermined temperature.

  At this time, the temperature detection element 33Af mounted on the power module 33A detects abnormal heat generation of the power module 33A. The microcomputer 35 determines that at least one of the two sets of stator windings is abnormal by detecting abnormal heat generation of the temperature detection element 33Af mounted on the power module 33A.

  The temperature detection element 33Bf mounted on the power module 33B detects abnormal heat generation of the power module 33B. The microcomputer 35 determines that the corresponding pair of stator windings (stator winding 21b) is abnormal, based on the detection result of the abnormal heat generation of the power module 33B and the detection result of the power module 33A.

And a detection element (temperature detection element 33Af) for detecting the state of the module (power module 33A).

  According to the control apparatus-integrated dynamoelectric machine 1 of this embodiment, at least one module 33A controls two different sets of stator windings 21b and 21c. The state of the at least one module 33A is detected by a temperature detection element. In this case, by detecting the state of at least one module 33A with one temperature detection element, the state of the two sets of stator windings (whether an abnormality has occurred) can be detected.

  This indicates that the detection of abnormality in the entire rotating electrical machine 1 can be performed by one detection element, and conventionally, only the same set of stator windings is controlled, and the abnormality in the entire rotating electrical machine 1 is controlled. Since detection needs to be performed with two detection elements, the number of detection elements installed in this embodiment can be reduced. Further, it is shown that the number of connections of the microcomputer 35 (the number of communication ports of the microcomputer 35) to which the detection element and the detection result are sent can be reduced. This can suppress coarsening of the physique of the microcomputer 35 and the control board (wiring board 30) on which the microcomputer 35 is mounted. In addition, since one detection element can be provided, the processing time required for abnormality detection can be shortened.

  According to the control apparatus-integrated dynamoelectric machine 1 of the present embodiment, at least one module (power module 33A) is not close to the annular open portion. For this reason, even when heat dissipation occurs in the annular open portion, the heat of at least one module (power module 33A) can be prevented from radiating from the open portion. As a result, a decrease in detection accuracy due to the detection element can be suppressed.

  Further, modules other than at least one module (power modules 33B and 33C) are installed between at least one module (power module 33A) and the annular open portion. In this case, the heat of modules (power modules 33B and 33C) other than at least one module (power module 33A) can be radiated at the annular open portion.

  Specifically, the distance (heat transfer distance via the control board) between the first module (power module 33A) for detecting the state (abnormality) of the stator windings 21b and 21c and the annular open portion is increased. Even when the first module (power module 33A) generates heat, it is difficult to transfer heat to the annular open portion, and heat is not easily generated from this portion.

  Further, the second module (power modules 33B and 33C) is positioned between the first module (power module 33A) and the annular open portion, and the first module (power module 33A) generates heat. Even in this case, even if heat transfer is performed in the circumferential direction toward the annular open portion, the second modules (power modules 33B and 33C) disposed therebetween inhibit the heat transfer.

  According to the control apparatus-integrated dynamoelectric machine 1 of the present embodiment, since the filling member 38 is filled (potted with resin), the temperature detection elements (temperature detection elements 33Af, 33Af, 33C, power modules 33A, 33B, 33C) 33Bf, 33Cf) can reduce the influence of ambient temperature. Moreover, when a foreign substance exists in the power converter (control device 3), the filling member 38 (potted resin) can suppress the contact and collision of the foreign substance.
