Description

Изобретение относитс к электрическим машинам, а именно к электрическим унипол рным машинам с жидко- металлическим контактом.The invention relates to electric machines, namely to electric unipolar machines with a liquid-metal contact.

Цель изобретени - повьшение надежности многодисковой унипол рной машины.The purpose of the invention is to increase the reliability of the multidisk unipolar machine.

На чертеже схематически изображен продольный разрез многодисковой унипол рной машины с параллельным соединением корных дисков (обмотка возбуждени не показана).The drawing shows schematically a longitudinal section of a multi-disk unipolar machine with parallel connection of the crustal discs (excitation winding not shown).

В цилиндрический корпус статора впрессованы неподвижнъте диски 2.In the cylindrical stator housing are pressed still disks 2.

Между ними р- змещены вращающиес дис- 15 вого смещени дисков.Between them are located rotating disc displacement of the disks.

Зазоры между вращающимис и неподвижными дисками заполнены жидким металлом, осуществл ющим электрический контакт между дисками ста- 20ki 3 of the rotor, pressed onto the shaft 4. The gaps between the rotating and stationary disks are filled with liquid metal that makes electrical contact between the disks of the

The side surfaces of all the disks are covered with electrically insulating material, in addition they are isolated from the shaft 4 and from the housing 1. The inner 5 and outer 6 contact 25 surfaces are not insulated.

Предлагаемое устройство работает следующим образом.The proposed device works as follows.

При вращении ротора в дисках наводитс ЭДС. Ток, генерируемый ЭДС, 30 замыкаетс по диску ротора 3, контакт- -ной поверхности 5, жидкому Металлу в боковом зазоре 7 и контактной поверхности 6. Взаимодействие тока в жидком металле зазора 7 с магнитным 35 полем, которое направлено вдоль оси машины, заставл ет вращатьс практини дисков.When the rotor rotates, the emf is induced in the disks. The current generated by the EMF 30 is closed along the rotor disk 3, the contact surface 5, the liquid Metal in the side gap 7 and the contact surface 6. The interaction of the current in the liquid metal gap 7 with the magnetic 35 field, which is directed along the axis of the machine, causes rotate practical disks.
