Title:
DEVICE FOR PREVENTING THE CREATION OF NARROWBAND STRAY RADIATION SPECTRA IN A PULSE-WIDTH MODULATED CONTROL SYSTEM OF A D.C. MOTOR
Document Type and Number:
WIPO Patent Application WO2003071669
Kind Code:
A3
Abstract:
The aim of the invention is to avoid the creation of narrowband stray radiation spectra caused by a pulse-width modulation control system (5) of a d.c. motor (1). To this end, switching means (8) are used to modulate the clock pulse frequency of the pulse-width modulated control signal.
