1. A method of operating a flux-mnemonic permanent magnet synchronous machine (FMPMSM), the FMPMSM comprising:
an annular stator having a winding;
a rotor disposed with a stator, the rotor comprising:
at least two permanent magnets, each of the permanent magnets having two poles normal to an air gap between the stator and rotor, the air gap having a nullified flux, both permanent magnets comprising a single magnet type with a coercivity less than 2000 Oe; and
one or more flux adjusters adjacent to one or more poles of at least one of the permanent magnets; and
a power inverter for dispensing at least one current pulse, wherein the power inverter has a microcontroller;
the method comprising:
realizing a first valued operational parameter by applying at least a first current pulse from the inverter to set a magnetic flux linkage between the rotor and stator; and
realizing a second valued operational parameter by applying at least a second current pulse to adjust the magnetic flux linkage to a magnetization state.
