Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO2003085805
Kind Code:
A3
Abstract:
A rotating electric machine comprising a stator having a first group of windings; a power source for selectively energizing the first group of windings; and a rotor having a first permanent magnet to be magnetically coupled with said first group of windings. The rotor also includes an axis of rotation that passes perpendicularly through the center of the first permanent magnet and the rotor is to rotate the first permanent magnet about the axis of rotation. The rotating electric machine may be configured to work as an electric motor or an electric power generator, or both. In either mode, the rotor is rotatable in the vacuum chamber therefore the magnetic interactions between the winding and the permanent magnet can be improved.
