Abstract
Electrical components of a rotating electric machine system includes a plurality of capacitors and a plurality of power modules. A first principal surface of each of the capacitors and a second principal surface of each of the power modules are arranged to surround a rotating shaft part such that the normal directions of the first principal surface and the second principal surface are directed along a radial direction of the rotating shaft part. Each of the capacitors and each of the power modules are arranged such that the axial positions thereof at least partially overlap each other.
Claims14
A rotating electric machine system comprising:
- a rotating electric machine including a rotor provided with a rotating shaft part, the rotating electric machine being configured to be driven by alternating current electrical power;
- and
- an electrical component configured to convert direct current electrical power into the alternating current electrical power,
- wherein the electrical component includes a plurality of capacitors and a plurality of power modules,
- the power modules and the capacitors each include:
- a principal surface;
- and
