Abstract
An electrical rotating machine system that can be easily maintained and can provide improved power generation efficiency. The electrical rotating machine system includes: a first electrical rotating machine having a first stator that has first stator windings, and a first rotor that has first rotor windings and is disposed on the internal diameter side of the first stator so as to have a gap between the internal diameter side of the first stator and the first rotor itself; a second electrical rotating machine having a second stator that has second stator windings, and a second rotor that has second rotor windings and is disposed on the internal diameter side of the second stator so as to have a gap between the internal diameter side of the second stator and the second rotor itself; and at least one power converter that is electrically connected to the first rotor windings and the second rotor windings, and configured to rotate when the first rotor rotates.
