Abstract
An electric generator that converts mechanical energy to electrical energy includes, among other things, a first axial flow electrical machine that includes a first rotor mounted in rotation about a first axis and surrounding a first stator; a second axial flow electrical machine that includes a second rotor coaxial to the first rotor and surrounding a second stator; and first azimuthal securing means that joins together the first and second rotors so that the first and second rotors can be simultaneously set in rotation about the first axis. The electrical generator may be used as part of a wind turbine.
Claims12
An electric generator allowing the conversion of mechanical energy to electrical energy, comprising at least:
- a first axial flow electrical machine comprising a first rotor mounted in rotation about a first axis and surrounding a first stator to generate a first magnetic flow;
- a second axial flow electrical machine comprising a second rotor separate from the first rotor, which is coaxial to the first rotor and surrounds a second stator to generate a second magnetic flow;
- and
- first azimuthal securing means to secure the first and second rotors so that the first and second rotors can be simultaneously set in rotation about the first axis to generate the first and second magnetic flows simultaneously.
