METHOD FOR CONTROLLING INDUCER ENGINE (VARIANTS) Russian patent published in 2006 - IPC H02P8/12 H02P6/00 

FIELD: electric engineering, possible use in railroad train.

SUBSTANCE: in the method for controlling inducer engine, trajectory of signals of upper and lower settings of phase current of "current corridor" are received as a result of comparison of sinusoidal modulating signal of double frequency, determining desired type of current setting, which lags relatively to front of rotor position sensor and is shifted into positive area relatively to zero, with signal, appropriate for minimal value of "current corridor", or "trajectory" of signals of upper and lower settings of phase current of "current corridor" is received as a result of comparison of sinusoidal modulating signal of triple frequency, determining desired type of current setting, which lags relatively to front of rotor position indicator and is shifted relatively to zero into positive area, with signal, appropriate for maximal value of "current corridor". As a result due to synchronized forming of phase currents in such a way, that total momentum of individual phases, being under currents simultaneously, provides for decrease of "burst" in resulting momentum curve.

EFFECT: decreased momentum pulsations.
