Electrical machine including two rotors and at least two bearings, with a single bearing arranged between the two rotors along the axis of rotation

The machine (10) has a shaft (22) movable in rotation around an axis of rotation (X). End bearings (24, 26) and an intermediate bearing (28) support two rotors (16, 20) and the shaft, where each rotor is interdependent of the shaft. The intermediate bearing is located between the rotors along the ax...

Zusammenfassung:The machine (10) has a shaft (22) movable in rotation around an axis of rotation (X). End bearings (24, 26) and an intermediate bearing (28) support two rotors (16, 20) and the shaft, where each rotor is interdependent of the shaft. The intermediate bearing is located between the rotors along the axis of rotation. Each bearing is a magnetic bearing, an oil bearing, a water bearing, a gas bearing or a roller bearing. The rotors are positioned inside a single frame (12). Stators (14, 18) drive the rotors in rotation.
