Mathematical Description of an Asynchronous Motor with the Indirect Control of the Output Mechanical Variables

Abstract: Abstract. The article gives the mathematical description of an asynchronous motor with the indirect control of the output mechanical variables of an asynchronous motor in the electric drive. To determine the electromagnetic torque and angular velocity of the asynchronous motor in the electric drive the mathematical description is used in which the values are determined by the readings of the motor and easily measured values by means of known in practice devices. The proposed in the article the mathematical des… Show more

“…Besides, if the motor rotation speed increases, the time of valve conducting state decreases. The linear relationship of conductance angle of valve, armature current and motor rotation speed proportion at different control angles is detected [6][7][8][9][10]. Figure 5 shows the results of electromagnetic calculations for the system at different converter control angles θ.…”

“…Для математического описания способа косвенного контроля выходных координат АД с помощью устройства косвенного контроля (УКК) можно воспользоваться нижеследующими выражениями, согласно которым возможно осуществлять контроль момента и угловой скорости АД по каталожным данным двигателя и легко измеряемым величинам [13][14]: Приведены аналитические выражения для математического описания способов косвенного контроля момента и угловой скорости асинхронного двигателя (АД) с помощью устройства косвенного контроля, позволяющие с заданной точностью рассчитать значения электромагнитного момента и угловой скорости АД и проводить их непрерывный контроль для обеспечения заданных технологических параметров в различных режимах работы общепромышленных механизмов. Приведены блок-схемы устройства косвенного контроля выходных механических переменных АД, реализованные на математическом описании способов расчета электромагнитного момента и угловой скорости АД, с различной точностью.…”
