Description

Предлагаетс  устройство дл  записи кривой крут щих моментов асинхронного двигател  при разбеге.A device is proposed for recording the torque curve of an induction motor during a takeoff run.

Известные устройства подобного рода, основанные на измерении ускорений, имеют сложную конструкцию и не дают значений крут щих моментов в функции скорости, между тем как эта характеристика  вл етс  важнейшей дл  короткозамкнутых асинхронных двигателей.The known devices of this kind, based on the measurement of accelerations, have a complex structure and do not give torque values as a function of speed, whereas this characteristic is the most important for short-circuited asynchronous motors.

Предлагаемое устройство проще известных и позвол ет получить указанную характеристику благодар  выполнению датчика в виде дву.ч электрических мащин-тахометрического генератора и индикатора ускорени , сид щих на одном валу с маховой массой, а также подключению в регистрирующем приборе пищущего миллиамперметра к индикатору ускорений и питанию двигател  лентопрот жного механизма от тахометрического генератора.The proposed device is simpler known and allows to obtain the indicated characteristic due to the sensor in the form of a two-hour electric tachometer generator and acceleration indicator, sitting on the same shaft with the fly-weight, and connecting a milli-meter gauge to the acceleration indicator and the engine power supply in a recording device. the tape mechanism from the tachometer generator.

Дл  усилени  напр жени  мандины-индикатора ускорений - может быть применен фотокомпенсациопный усилитель.To increase the voltage of the accelerator mandin-indicator, a photo-compensating amplifier can be used.

На фиг. 1 схематично изображено предлагаемое устройство; на фиг. 2 - его индикатор ускорений.FIG. 1 schematically shows the proposed device; in fig. 2 is its acceleration indicator.

Устройство состоит из датчика и регистрирующего прибора.The device consists of a sensor and a recording device.

Датчик выполнен в виде двух электрических машин, сид щих на общем валу с маховой массой /, к которой присоедин етс  испытуемый двигатель 2. Одна из мащин - тахометрический генератор 3 - дает на регистрирующий прибор э.д.с., характеризующую скорость вращени  двигател .The sensor is made in the form of two electric machines, sitting on a common shaft with a ground mass /, to which test engine 2 is attached. One of the machines, a tachometric generator 3, provides an emf to the recording device, which characterizes the speed of rotation of the engine.

Втора  мащина 4 служит индикатором ускорений.The second mask 4 serves as an indicator of acceleration.

Основной деталью этой мащипы  вл етс  статор 5 {фиг. 2). На нем расположены две обмотки б и 7, магнитные оси которых взаимно перпендикул рны . В воздущном зазоре между статором и неподвижным сердечником 8 вращаетс  пустотелый цилиндр 9, соединенный с валомThe main part of this machine is the stator 5 {fig. 2). It has two windings b and 7, whose magnetic axes are mutually perpendicular. In the air gap between the stator and the fixed core 8, a hollow cylinder 9 rotates, which is connected to the shaft
