Drive unit integrated rotating electrical machine
ProblemTo obtain a drive unit integrated rotating electrical machine that makes it easier to connect power circuits and achieves not only excellent vibration resistance but also excellent heat releasing properties.Means for SolutionA drive unit integrated rotating electrical machine has a motor, a drive unit driving the motor under control and provided with power switching elements and conductors passing a current to the power switching elements, and a heat sink cooling the drive unit, which are combined into one unit. The drive unit integrated rotating electrical machine is characterized in that: the power switching elements are molded and formed into mold modules in a state in which terminals thereof are exposed; the conductors are insert-molded in a frame in a state in which terminals thereof are exposed; and the exposed terminals of the mold modules are connected to the exposed terminals of the insert-molded conductors and the mold modules are firmly fixed to the heat sink.
