Title:
METHOD FOR REGULATING THE ROTATIONAL SPEED OF A MOTOR AND A MOTOR FOR CARRYING OUT A METHOD OF THIS TYPE
Document Type and Number:
WIPO Patent Application WO2001022095
Kind Code:
A8
Abstract:
The invention relates to a method for regulating the rotational speed of a motor, to which a digital governor is assigned and which during operation generates an actual value signal for the rotational speed in the form of a rotational speed frequency signal, to a rotational speed theoretical value which is predetermined in the form of a theoretical value frequency signal. Said method consists of the following steps: in a first time phase, a first numerical frequency value which characterises the rotational speed of the motor is determined from the speed frequency signal; in a second time phase, which is approximately synchronous with the first time phase, a second numerical frequency value which characterises the frequency of the theoretical value frequency signal is determined from the theoretical value frequency signal; The first and second numerical frequency value are used to regulate the rotational speed of the motor in the digital governor to a speed which is assigned to the theoretical frequency signal according to a predetermined mathematical relationship.
