<p>A method of characterizing a rotating electromagnetic machine. The machine, such a switched reluctance machine, has a stator, a rotor and a plurality of phases of energizable windings. The method of characterizing includes turning the rotor, injecting a plurality of diagnostic pulses into at least one of the phase windings, and determining a rotor position profile based on detected characteristics of the diagnostic pulses. A predetermined rotor position profile describing the relationship between diagnostic values and rotor positions may be stored in a memory accessible by the machine's processing device. Diagnostic values corresponding to aligned and unaligned rotor positions for the rotating electromagnetic machine are determined and the predetermined rotor position profile is modified based on the determined diagnostic values corresponding to the aligned and unaligned rotor positions.</p> |
