Description
(54) КОЛЛЕКТОРНЫЙ ЭЛЕКТРОДВИГАТЕЛЬ(54) COLLECTOR MOTOR
С УСТРОЙСТВОМ ИЗМЕРЕНИЯ СКОРОСТИ ВРАЩЕНИЯWITH DEVICE OF MEASURING THE SPEED OF ROTATION
Устройство.работает следующим образом.The device works as follows.
Генератор высокочастотного напр жени 7 работает на последовательную цепь состо щую из обмотки 6 и блока формировани измер емого сигнала 8. При вращении электродвигател , коллекторные пластины 2 пересекают высокочастотное магнитное поле, создаваемое обмоткой 8 датчика сигнала, что приводит к периодическому изменению с частотой вращени электродвигател полного сопротивлени датчика сигнала и, как слествие , к модул ции тока через обмотку 6 датчика и напр жени блока формировани измер емого сигнала. Причем , частота модул ции пропорциональна скорости вращени . Измеритель скорости 9 измен ет частоту выходного сигнала блока 8, котора пропорциональна скорости вращени электродвигател . То обсто тельство, что коллектор 1 электродригател одновременно выполн ет роль модулирующегоThe high-frequency voltage generator 7 operates on a series circuit consisting of a winding 6 and a measuring signal forming unit 8. When the electric motor rotates, the collector plates 2 intersect the high-frequency magnetic field created by the signal sensor winding 8, which causes a periodic change in the full motor frequency resistance of the sensor signal and, as a consequence, to the modulation of the current through the winding 6 of the sensor and the voltage of the unit forming the measured signal. Moreover, the frequency of modulation is proportional to the speed of rotation. A speed meter 9 changes the frequency of the output signal of block 8, which is proportional to the speed of rotation of the motor. The fact that the electric collector 1 collector simultaneously performs the role of modulating
элемента датчика скорости позвол ет упростить конструкцию электродвигател .element speed sensor allows you to simplify the design of the electric motor.
