Abstract: A controller integrated rotating electrical machine is designed to minimize adverse thermal effects on a control device. The controller device includes switching modules, a control circuit, and a casing. The switching modules are disposed inside the casing at a distance from a rear housing. The control circuit is disposed in the casing and located in front of the switching modules at a distance from the rear housing and the switching modules. In other words, the control circuit is arranged away from the switching modules which are a heat source when operating, thereby eliminating adverse thermal effects on the control circuit.

Abstract: In a vehicle, a control apparatus controls a power converter supplying a rotary machine which can operate as a drive motor of the vehicle, and controls a cooling apparatus for circulating a coolant fluid through the rotary machine and the power converter. When a temporary condition occurs immediately after commencement of the circulation, whereby the temperatures of the coolant fluid and of switching elements in the power converter are judged to concurrently exceed respective specified temperature thresholds, the control apparatus limits the maximum power that can be supplied from the power converter to a lower value than is normally available. When the temperature of the coolant fluid is judged to no longer exceed the corresponding temperature threshold, the limiting is released.
