MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617072172 A) filed by Brose Fahrzeugteile Se & Co. on June 10, 2026, for Method For Operating An Electric Motor.
Inventor includes Schwarzkopf, Johannes.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The invention relates to a method for operating an electric motor (4) by means of pulse width modulation, in which, during a period duration (Tperiode), at least one pulse width modulated signal pulse (70) is generated at a pulse position (T0) with a pulse duration (Ton), wherein a resulting amplitude spectrum (64) has an amplitude value (A) at a critical frequency (?kritisch), wherein at least one time parameter (Tperiode, T0, Ton) of the pulse width modulation is replaced by a sum of the time parameter (Tperiode, T0, Ton) and a correction factor (Tkorr), wherein the correction factor (Tkorr) is changed in such a way that a calculated amplitude spectrum (64') at the critical frequency (?kritisch) has a reduced amplitude value (Iamp), and wherein the pulse width modulation is performed with the time parameter (Tperiode, T0, Ton) and the modified correction factor (Tkorr).
