Abstract
A method controls a motor using pulse width modulation (PWM). The method involves measuring the PWM frequency; determining the carrier frequency of a set radio transmitter; and matching the PWM frequency to the carrier frequency of the radio transmitter in such a manner that an integer multiple of the PWM frequency corresponds to the carrier frequency or an integer multiple of the PWM frequency lies in the middle between two carrier frequencies.
