PROCESSING DEVICE, ELECTRIC VEHICLE, PROCESSING METHOD AND PROGRAM Russian patent published in 2025 - IPC H02P23/04

Abstract RU 2840717 C2

FIELD: electricity.

SUBSTANCE: invention relates to processing means for use in excitation of electric motor. Processing device (400) sets amplitude of fifth harmonic (I₅) so that ratio of amplitudes (A₅) makes from 20% to 80%. Besides, processing device (400) establishes phase difference (ϕ₅) so as to make the phase of the fifth harmonic relative to the main wave the leading phase and to make the phase difference (ϕ₅) of 80° up to 106°.

EFFECT: increased effect of electric motor vibration suppression.
