FIELD: electricity.
SUBSTANCE: method provides automatic excitation control of a synchronous drive motor of a multimachine aggregate of an excavator by excitation current regulation according to a specific signal which is generated as total reference constant signal, first correcting signal generated as constant voltage if observing an effective value of power voltage decreased below an allowable level, and second correcting signal generated as constant voltage if observing a command device in a lifting position exceeding a preset threshold value, measurement of total electric capacity of main motion drives, addition of the derived value and the reference signal and the first correcting signal, comparison of two calculated totals and generation of the specific excitation current signal equal to a maximum of two totals.
EFFECT: higher dynamic stability of the synchronous drive motor of the excavator in various operation modes.
