Description

При питании электромагнита синусоидальным током возможно по  вление вибраций  кор  в том случае, если противодействуюнхее усилие больше или равно мгновенному значению силы на  коре.When the electromagnet is supplied with a sinusoidal current, the vibration of the core may appear if the opposing force is greater than or equal to the instantaneous value of the force on the core.

Один из известных способов устранени  этого  влени  заключаетс  в разложении основного магнитного потока на два сдвинутых по фазе потока с тем, чтобы при переходе одного из потоков через нуль другой обеспечивал какую-то минимальную величину силы трнт жени   кор . Дл  получени  указаппого сдвига электромагнит снабжаетс  двум  обмотками , из которых одна включаетс  непосредственно па сеть, а друга  - через емкость, или же примен етс  короткозамкнутое кольцо, охватывающее часть магнитного потока.One of the known methods for eliminating this phenomenon is to decompose the main magnetic flux into two phase-shifted fluxes, so that when one of the fluxes passes through zero, the other provides some minimum value for the crp strength. To obtain a shear magnet, the electromagnet is supplied with two windings, one of which is connected directly to the mains and the other through the capacitor, or a short-circuited ring covering a part of the magnetic flux is used.

С целью упрощени  конструкции и уменьщени  габаритов электромагнита , предлагаетс  дл  разлолсени  основного магнитного потока на две сдвинутые по фазе составл ющие использовать разность размагнпчивающих действий вихревых токов в магпитопроводе электромагнита, набранном из двух материалов с листами разной толщины и с различным удельным электрическим сопротивлением.In order to simplify the design and reduce the size of the electromagnet, it is proposed to split the main magnetic flux into two phase-shifted components using the difference in demagnetizing actions of eddy currents in an electromagnet magptopath composed of two materials with sheets of different thickness and with different specific electrical resistance.

В предлагаемом электромагните такет магнитопровода пабпрает м из листов двух сортов - листов минимальной толщины с больщпм удельным электрическим сопротивлением и листов с малым удельным электрическим сопротивлением и сравнительио больпюй толщины.In the proposed electromagnet, the magnet of the magnetic conductor is made of two types of sheets - sheets of minimum thickness with a large electrical resistivity and sheets with a small electrical resistivity and comparatively large thickness.

Вихревые токи в тонких листах свод тс  до минимума, а в листах больщей толщины, выполненных из материала с малым удельным эле); трическим сопротивлением, вихревые токи уве.тичиваютс . Величину требуемого угла сдвига можно регулировать соответствующим подбором толщин листов и марок материалов.The eddy currents in thin sheets are reduced to a minimum, and in sheets of greater thickness, made of a material with a small specific ale); trictive resistance, eddy currents are increased. The magnitude of the required shear angle can be adjusted by appropriate selection of sheet thicknesses and grades of materials.
