Description
ном соответственно, La - индуктивность экрана .Mr. respectively, La - screen inductance.
На чертеже представлена схема предлагаемого электродинамического возбудител колебаний .The drawing shows the scheme of the proposed electrodynamic exciter oscillations.
Устройство состоит из магнитоировода 1, на внзтреннем стерл не которого расположена неподвижна катзшка подмагничиванп 2. В кольцевом зазоре магнитопровода расположены подвижна катушка управлени 3 и корректирующа катушка 4, обш.ий каркас 5 которых жестко св зан с нагрузкой 6 возбудител . В кольцевом зазоре магнитопровода расположен таклсе экран, выполненный в виде двух короткозамкнутых колец 7.The device consists of a magnetic conductor 1, on the innermost notch of which there is a fixed quartz head of the magnetized 2. In the annular gap of the magnetic core there is a movable control coil 3 and a correction coil 4, the sheath frame 5 of which is rigidly connected to the load 6 of the exciter. In the annular gap of the magnetic circuit there is a screen, made in the form of two short-circuited rings 7.
Устройство работает следующим образом.The device works as follows.
При подаче переменного тока в катушку управлени 3 опа под действием электродинамических сил пачинает совершать колебани , которые через каркас 5 передаютс в пагрузку 6. При этом в корректируюшей катушке 4 протекает ток, обусловленный суммарным действием э.д. с. движени , э. д. с. взаимной индукции между катушкой управлени и корректирующей катушкой и э. д. с., наведенной потоком, образуемым током экрана. Если взаимные индуктивности катушек и экрана выбраны из соотношени When an alternating current is applied to the control coil 3, the opa, under the action of electrodynamic forces, saves to make oscillations, which are transmitted through the frame 5 to the load 6. At the same time, a current flows in the correcting coil 4 due to the total effect of em. with. movement e. d. mutual induction between the control coil and the correction coil and e. D. s., induced by the flow formed by the current screen. If the mutual inductances of the coils and the screen are chosen from the ratio
„МэуЛ кэ„Meul Kae
-V - f-V - f
то В корректирующей катушке достигаетс полна взаимна компенсаци индуктивных составл ющих э.д. с., благодар чему сигнал, снимаемый с этой катушки, будет пропорционален скорости движени , что позвол ет точно корректировать частотную характеристику возбудител в широком диапазоне частот.In the correction coil, the full mutual compensation of the inductive components of the emf is achieved. p., so that the signal taken from this coil will be proportional to the speed of movement, which allows you to accurately adjust the frequency response of the driver in a wide frequency range.
