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 3):
The magnetization state control method according to  claim 1 , wherein\n the trajectory of the flux linkage vector on the dq-axis plane has a substantially involute trajectory expressed by the following formula (1):\n d=\u03bb magnetize  cos(\u2212 p\u03c9t )\u2212 Vt  sin(\u03b8\u2212 p\u03c9t ) \n q=\u03bb magnetize  sin(\u2212 p\u03c9t )\u2212 Vt  sin(\u03b8\u2212 p\u03c9t ) \u2003\u2003(1) \n where \u03b8=cos \u22121 (\u03bb dq /\u03bb magnetize ), \u03bb dq  represents a base circle radius for the involute trajectory, \u03bb magnetize  represents a target flux linkage at a target magnetization, V represents a given voltage, p represents a number of pole pairs, \u03c9 represents a rotor rotating speed, and t represents time after the target magnetization, and\n the trajectory of the flux linkage vector on an \u03b1\u03b2-axis plane has a substantially straight trajectory, with the \u03b1\u03b2-axis plane being a stationary reference frame with an \u03b1-axis coinciding with a phase coil center and pointing in a direction in which a magnetomotive force is generated such that a magnet flux linkage increases when the \u03b1-axis coincides with the d-axis and a \u03b2-axis being 90 degrees ahead of the \u03b1-axis in the rotational direction of the rotor.
