Изобретение касаетс  измереНИН параметров движени .The invention relates to measurement of motion parameters.

Известные устройства, примен е1лые дл  этой же цели содержат частотомер, подгшюченныи к одной из обмоток электродвигател  посто нного тока.The known devices used for the same purpose contain a frequency meter that is connected to one of the windings of the DC motor.

Цель изобтоетенрш - упрощение конструшдии и получение линейной зависимости частоты от скорости вращени .The goal of isobtoteens is to simplify the construction and to obtain a linear dependence of the frequency on the rotational speed.

Дл  этого в предлагаемом устройстве частотомер подключен к компенсационной обмотке  кор , соответствующей полюсному делению электродвигател  посто нного тока.For this, in the proposed device, the frequency meter is connected to the compensation winding of the core corresponding to the pole division of the DC motor.

На чертеже представлена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

Тахометр содержит  корь I с компенсационной обмоткой 2, подключенно к частотомеру 3,The tachometer contains measles I with compensation winding 2, connected to the frequency meter 3,

В компенсационной обмотке индуцируетс  э,д,с. За счет пульсацйи магнитного потока, вызываемог относительным переглещением зубцов  кор  относительно полкюных башглаков статора 4, форла кривой э,д,с, близка к синусоидальной. Частота э.д.с. линейно зависит от скорости вращени   кор  во всем диапазоне скоростей и не зависит от нагрузки машины. Таким образом, показание частотомера будет соответствовать скорости вращени  электродвигател ,In the compensation winding, e, d, c is induced. Due to the pulsation of the magnetic flux, caused by the relative re-pinching of the teeth of the core relative to the polkyuyny baffles of the stator 4, the forl of the curve e, d, s is close to sinusoidal. Emf frequency linearly depends on the speed of rotation of the core in the entire range of speeds and does not depend on the load of the machine. Thus, the reading of the frequency meter will correspond to the rotational speed of the motor,

ПРЕКЖГ ИЗОБРЕГЕНШPREKZHG ISOBREGENSH

Тахометр, содеркащий частотомер , подютюченный к одной из обмоток электродвигател  посто нного тока, отличакшщйс  .тем,что, с целью упрощени  конструкции и получени  линейной зависимости частоты от скорости вращени , частотомер подключен к компенсационной обмотке  кор .A tachometer containing a frequency meter podtyuchenny to one of the windings of a DC motor is different because, in order to simplify the design and to obtain a linear dependence of the frequency on the speed of rotation, the frequency meter is connected to the compensation winding box.
