Driving-device-integral-type rotary electric machine

摘要

A driving-device-integral-type rotary electric machine includes a driving device 8 having a first inverter 27a and a second inverter 27b, which can supply power to stator windings 5a and 5b of the rotary electric machine 2, and the first inverter 27a and the second inverter 27b are arranged and installed in a heat sink 19, in a state where the inverters are linearly symmetrical with respect to an axis X of the rotary electric machine 2, and the heat sink is configured in such a way that at least a heat capacity of a portion with respect to the first inverter 27a is roughly equal to a heat capacity of a portion with respect to the second inverter 27b.
