Abstract

СПОСОБ КОСВЕННОГО КОНТРОЛЯ НЕРАВНОМЕРНОСТИ ВОЗДУШНОГО ЗАЗОРА ЭЛЕКТРИЧЕСКОЙ МАШИНЫ по авт. св. № 541246, отличающийс  тем, что, с целью повышени  точности, измер ют амплитуду и среднее значение разности ЭДС, наведенных в двух фазах , не подключенных к напр жению, частоту указанного напр жени  выбирают по крайней мере на пор док больше частоты вращени  ротора, а контролируемый сигнал формируют как отношение разности максимального амплитудного значени  и среднего арифметического результатов измерени  средних значений разности ЭДС к этому среднему арифметическому.METHOD OF INDIRECT CONTROL OF THE UNEVENITY OF THE AIR GAP OF THE ELECTRIC MACHINE by author. St. No. 541246, characterized in that, in order to improve accuracy, the amplitude and average value of the difference in emf induced in two phases not connected to the voltage are measured, the frequency of said voltage is chosen at least an order of magnitude higher than the rotor speed, the monitored signal is formed as the ratio of the difference between the maximum amplitude value and the arithmetic average of the measurement results of the average values of the difference between the emf and this average arithmetic value.
