PROBLEM TO BE SOLVED: To provide a rotary electric machine unit that is able to restrain an operation so as to prevent both an element temperature and a device temperature from increasing beyond corresponding set-temperatures.SOLUTION: A rotary electric machine unit comprises: a rotary electric machine 21; a plurality of switching elements Sp, Sn for electrically conducting or cutting off the rotary electric machine for each phase; a control device 23 that controls an operation of the rotary electric machine by controlling the plurality of switching elements; a first temperature detecting section that detects a temperature of each switching element as an element temperature; and a second temperature detecting section 29 that detects a temperature of the control device as a device temperature. The control device controls the switching elements so as to prevent the element temperature detected by the first temperature detecting section from becoming higher than an element set-temperature, which is set for each switching element and so as to prevent the device temperature detected by the second temperature detecting section from becoming higher than a device set-temperature, set for the control device.SELECTED DRAWING: Figure 2

    【課題】素子温度と、装置温度のどちらの温度も、対応する設定温度を超えて高くなることがないように動作抑制することが可能な回転電機ユニットを提供する。【解決手段】回転電機21と、回転電機の相ごとの通電及び遮断を行う複数のスイッチング素子Sp,Snと、複数のスイッチング素子を制御することにより、回転電機の動作を制御する制御装置23と、スイッチング素子の温度を素子温度として検出する第一温度検出部と、を備え、制御装置の温度を装置温度として検出する第二温度検出部29を備え、制御装置は、第一温度検出部により検出された素子温度がスイッチング素子に対して設定される素子設定温度よりも高くなることを抑制し、且つ、第二温度検出部により検出された装置温度が制御装置に対して設定される装置設定温度よりも高くなることを抑制するように、スイッチング素子を制御する回転電機ユニット。【選択図】図2
