Изобретение относитс к способам проверки обмоток коллекторных электрических машин , в частности, при производстве электродвигателей .The invention relates to methods for checking the windings of collector electric machines, in particular, in the manufacture of electric motors.
Известны способы обнаружени обрыва, неправильной укладки, витковых замыканий в обмотках корей коллекторных элетрических машин путем индуктировани э.д.с. в секци х при вращении кор машины с большой скоростью .Methods are known for detecting breakages, improper installation, winding short circuits in the windings of Korean collector electrical machines by inducing emf. in sections when the machine rotates at high speed.
Недостатком известных способов вл етс ухудшение в результате испытаний качества поверхности коллектора за счет следов, остаюш ,ихс на коллекторе от металлических ш,упов . Целью предложенного способа вл етс устранение нарушени поверхности коллектора при проверке корной обмотки электрической машины.A disadvantage of the known methods is the deterioration as a result of testing the quality of the surface of the collector due to traces, remaining, on the collector from metal w, ups. The purpose of the proposed method is to eliminate the disturbance of the collector surface when checking the core winding of an electric machine.
Поставленна цель достигаетс вращением индуктора и приемника вокруг неподвижного кор .The goal is achieved by rotating the inductor and receiver around a fixed core.
На чертеже изображена принципиальна схема устройства осуществл ющего способ.The drawing shows a schematic diagram of a device carrying out the method.
Испытуемый корь 1 устанавливаетс на опоре и зажимаетс цангой 2. К индуктору 3 подключаетс источник переменного или посто нного тока. При обнаружении обрыва, неправильной укладки на коллектор 4 устанавливаетс колодка 5.The test bark 1 is mounted on a support and clamped by the collet 2. An alternating current or direct current source is connected to the inductor 3. Upon detection of a breakage, improper installation on the collector 4 is installed block 5.
При вращении барабана 6 двигателем 7 совместно с индуктором 3 вокруг кор поочередно засвечиваютс фотодноды 8. Это позвол ет вход осциллографа 9 при помощи формировател 10 подключать к двум соседним ламел м и наблюдать наличие дефекта в корной обмотке.When the drum 6 is rotated by the motor 7 together with the inductor 3 around the core, the photodnods 8 are alternately illuminated. This allows the input of the oscilloscope 9 to be connected to two adjacent lamellas by means of the shaper 10 and observe the presence of a defect in the core winding.
При проверке наличи внтковых замыканий на индуктор 3 подаетс напр жение повышенной частоты. При помощи двигател индуктор 3 и приемник 1 i вращаютс вокруг кор с большой скоростью. Если в секци х есть хоть один замкнутый виток, магнитные св зи между индуктором 3, корем н приемником нзмен ютс . Это привод т к резкой модул ции сигналов, постунащих на осциллограф 9.When checking for the presence of short circuits, an inductor 3 is energized at an increased frequency. With the help of a motor, the inductor 3 and the receiver 1 i rotate around the core at high speed. If there are at least one closed loop in the sections, the magnetic coupling between the inductor 3 and the receiver is replaced. This results in a dramatic modulation of the signals posting to the oscilloscope 9.
