Original abstract

This paper deals with influence of temperature on behaviour of magnetic drive. The permanent magnets that are used for torque transmission cannot be used close to Currie point, which is a point of loss of magnetic characteristics. We intend to use the magnetic drive for pump of radioactive liquid materials for transmutation devices, where the temperature is close to four hundred centigrade. This paper presents experimental results, suggests the design changes for elimination of temperature influence and tooth shape optimization.

Czech abstract

Článek se zabývá vlivem teploty na vlastnosti magnetické spojky, která využívá pro přenos kroutícího momentu permanentních magnetů, které nemohou být používány nad teplotu označovanou jako "currie point". Plánované použití magnetické spojky je v čerpadle na kapalné soly pro transmutační zařizení, kde teplota přesahuje 400°C. Článek prezentuje výsledky experimentů a navrhuje změny koncepce mag. spojky za účelem eliminace vlivu teploty a optimalizaci tvaru zubu vnitřního rotoru spojky za účelem zvíšení přenášeného kroutícího momentu.
