Abstract: This invention relates to a bearingless constant frequency phase locked generator adaptable of variable torque. With a reasonable combination of rotor poles and stator poles configured with U type permanent magnets and windings respectively, this novel generator can, with no need for acceleration of gearbox and sequential electrical controls, produce constant frequency constant voltage output, and is capable of auto phase (of the grid, for example) tracing and/or locking through the electrical control of the turn on/off of individual stator windings. Further a bearingless design is adopted and initiative suppression of axis vibration can be achieved. This generator has a relative simple structure, lower cost and high wind energy conversion, and is adaptable for a wide range of wind speed. This generator can be connected to grid directly and is suitable for wind power generation and other applications.
