Description
(54) СПОСОБ ИЗМЕРЕНИЯ СТАТИЧЕСКОГО МОМЕНТА (54) METHOD FOR MEASURING THE STATIC MOMENT
. .
Изобретение относитс к измерительной технике и может быть использовано в автоматических электроприводах с переменной статической нагрузкой.The invention relates to a measuring technique and can be used in automatic electric drives with variable static load.
Известен способ измерени статического момента электродвигател путем определени разности сигналов, пропорциональных полному моменту электродвигател и динамическому 1.There is a known method for measuring the static moment of an electric motor by determining the difference of signals proportional to the total moment of the electric motor and the dynamic one.
Этот способ не обеспечивает требуемой точности измерени .This method does not provide the required measurement accuracy.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ измерени статического момента электродвигател , заключающийс в измерении электромагнитного момента и скорости вращени вала электродаигател , алгебраическом суммировании с последующим интегрированием сигнала, пропорщюшшьного электромагнитному моменту, и сигнала обратной св зи интегратора и вычитании из выходного сигнала интегратора сигнала пропорционального скорости вращени вала 2. ЭЛЕКТРОДВИГАТЕЛЯThe closest to the invention in technical essence and the achieved result is a method for measuring the static moment of an electric motor, consisting in measuring the electromagnetic moment and the rotation speed of the electrode shaft, algebraically summing and then integrating the signal proportional to the integrator and subtracting from the output signal integrator signal proportional to the speed of rotation of the shaft 2. MOTOR
Недостатком такого способа также вл етс низка точность измерени .The disadvantage of this method is also low measurement accuracy.
Целью изобретени вл етс повыщение точности измерени .The aim of the invention is to increase the measurement accuracy.
Указшша цель достигаетс тем, что согласно способу в качестве сигнала обратной св зи интегратора используют сигнал, пропорциональный разности между выходным сигналом интегратора и сигналом, пропорциональным скорости вращени вала электродвигател .This goal is achieved in that, according to the method, a signal proportional to the difference between the integrator output signal and a signal proportional to the rotation speed of the motor shaft is used as the integrator feedback signal.
