Abstract:
A magnetization state control method for a variable magnetization machine, the method includes generating a flux linkage vector while changing a magnetization state of the variable magnetization machine such that a trajectory of the flux linkage vector has a curved clockwise trajectory on a dq-axis plane and a magnitude of the flux linkage vector temporally changes, with the dq-axis plane being a synchronous reference frame with a d-axis pointing in a direction of a permanent magnet flux and a q-axis being 90 degrees ahead of the d-axis in a rotational direction of a rotor.

Claim (Index 4):
The magnetization state control method according to  claim 3 , wherein\n the trajectory of the flux linkage vector on the dq-axis plane has the substantially involute trajectory further expressed by the following formula (2):\n \u03bb dq \u2264\u03bb rated  \u2003\u2003(2) \n where \u03bb rated  represents a rated flux linkage at the given voltage and rotor speed.
