ROTARY ELECTRIC MACHINE WITH POWER CONVERTER

摘要

A rotary electric machine with a power converter includes: a stator that has stator windings; a rotor that has a rotor winding; a rotational position detecting sensor that outputs a rotational position signal of the rotor; a case that contains the stator and the rotor; a field module that is connected to the rotor winding; power modules, each of which is connected to each of the stator windings and has a current detector, a first switching element, and a second switching element; a heat sink fixed to the field module and the power modules; and a control substrate that outputs control signals to the field module and the power modules based on the rotational position signal from the rotational position detecting sensor. The first switching element is connected in series to the second switching element; and the current detector and both switching element are molded with insulating resin.
