Claim 11:
12. A flux-mnemonic permanent magnet synchronous machine (FMPMSM) having a derived internal voltage, the 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 a flux adjuster between the two poles of each of the permanent magnets;
a power inverter for dispensing a current pulse, wherein the power inverter has a voltage (Vps) greater than the derived internal voltage; and
an air gap between the stator and the rotor, wherein a magnetic flux density in the air gap is controllable by applying at least one current pulse from the power inverter to vary a polarization of magnetization of at least one of the permanent magnets at a first speed of the FMPMSM, and
wherein the derived internal voltage limits a relationship between the magnetization state of the at least one permanent magnet and the first speed of the FMPMSM.
