Rotating electric machine system and combined power system

A rotating electric machine system equipped with:

• a rotating electric machine provided with a rotor, the rotor including a permanent magnet and a rotating shaft;
• and a rotating electric machine housing configured to rotatably support the rotating shaft, the rotating electric machine system comprising:
• an electrical component provided at the rotating electric machine housing;
• and
• a first retaining member and a second retaining member provided on an outer circumferential portion of the rotating electric machine housing and configured to retain the rotating electric machine housing by a support member provided in a structural body to which the rotating electric machine system is installed,
• wherein the first retaining member and the second retaining member are arranged at positions spaced from each other in a circumferential direction of the rotating electric machine housing, and
• the electrical component is disposed at a position away from a portion between the first retaining member and the second retaining member in the outer circumferential portion,
• the rotating shaft includes a large diameter portion configured to support the permanent magnet, and a first small diameter portion and a second small diameter portion projecting from the large diameter portion in respective directions opposite to each other in an axial direction of the rotor,
• a first bearing is disposed between the rotating electric machine housing and the first small diameter portion,
• a second bearing is disposed between the rotating electric machine housing and the second small diameter portion, and
• the first retaining member is disposed in a part of the outer circumferential portion, which is a part of the rotating electric machine housing that surrounds the first small diameter portion.
