Claim 0:
1. A flux-mnemonic permanent magnet synchronous machine (FMPMSM) comprising:
an annular stator having a winding;
a rotor disposed concentric with the stator, the rotor comprising: at least two circumferentially magnetized adjustable permanent magnets, each of the permanent magnets having two poles normal to an air gap between the stator and rotor; and one or more flux adjusters adjacent to one or more magnet poles of the permanent magnets; and
a power inverter for dispensing an excitation current and at least one current pulse,
wherein a polarization ratio of magnetization of at least one of the permanent magnets is adjustable during operation of the FMPMSM by application of the at least one current pulse, and
wherein a magnetic flux density in the air gap is controlled during operation of the FMPMSM by adjusting the polarization ratio of the at least one permanent magnet.
