Device for determining the coordinates of an AC machine

Article preview

To increase the possibilities of application of alternating current electric drives with various control systems, including those mechanisms where the installation of a tachogenerator is inadmissible or undesirable, the Department of Electrical Machines and Automated Drive of LMI has developed a device that allows indirectly determine the speed of rotation, as well as the components of the stator and rotor flux-coupling of the induction motor (IM).

Control system of electric drive THR-AD with Microcomputer

Article preview

When organizing the control of the drive thyristor frequency converter - induction motor (TFC-AD) with sufficiently high speed, wide range of speed control and good economic indicators it is necessary on the basis of information about the coordinates of the AD state to form control actions on the frequency and voltage channels of TFC in accordance with certain algorithms.

Привод поворота шаровых мельниц по схеме ТПЧН-СД

Article preview

В ряде случаев при механизации ремонтных и вспомогательных работ, свя­занных с шаровыми мельницами, используется непосредственные преобразовате­ли частоты с небольшим диапазоном регулирования выходной частоты, работаю­щие в кратковременном режиме, не требующем оптимальной формы кривой выход­ного напряжения преобразователя и высокой точности поддержания угла открытия тиристоров. С другой стороны, к таким устройствам, как правило, предъявляются повышенные требования в отношении помехоустойчивости и на­дежности, поскольку их устанавливают в производственных помещениях с высо­ким уровнем промышленных помех ...
