Description

вращени  вала индукционной машины, амплитуда посто нна, а чередование фаз определ етс  нанравлением вращени . После дифференцировани  треугольного сигнала на выходах дифференциатора 7 получаютс  сигналы пр моугольной формы, амплитуда которых пропорциональна наклону треугольного сигнала, т. е. скорости вращени  вала. С помощью коммутатора 9 сигналы пр моугольной формы преобразуют посто нное напр жение, величина которого пр мо пропорциональна скорости вращени . Управление коммутатором 9 осуществл етс  с помощью формировател  сигналов управлени  8, выход которого также подключен коrotation of the shaft of the induction machine, the amplitude is constant, and the phase rotation is determined by the direction of rotation. After differentiating the triangular signal, the outputs of the differentiator 7 produce square-shaped signals, the amplitude of which is proportional to the slope of the triangular signal, i.e. the shaft rotation speed. By means of the switch 9, square-wave signals convert a constant voltage, the magnitude of which is directly proportional to the speed of rotation. The switch 9 is controlled by the control signal generator 8, the output of which is also connected to

входу формировател  импульсного выхода 10.the input of the pulse output 10.

Использование предлагаемого способа измерени  скорости вращени  обеспечивает повышенную точность измерени  скорости вращени  в сравнении с прототипом.Using the proposed method of measuring the rotational speed provides increased accuracy of the measurement of the rotational speed in comparison with the prototype.
