Abstract
A generator system comprises an inner generator rotor, an outer generator rotor, and a stator. The inner rotor is mounted on the first shaft rotating at a first speed, while the outer rotor is mounted on a second shaft coaxial with the first shaft, and rotating at a second speed different from the first speed. The outer rotor is mounted coaxially with and radially outward of the inner rotor, and the stator is mounted coaxially with and radially outward of the outer rotor.

2 more elements
A multi-rotor generator comprising:
- an inner rotor mounted on a first rotating shaft configured to rotate at a first speed range;
- an outer rotor mounted concentric with and radially outward of the inner rotor, on a second rotating shaft concentric with the first rotating shaft and configured to rotate at a second speed range not equal to the first speed range;
- a stator mounted concentric with and radially outward of the outer rotor.
