Problems solved by technology

But it has the big disadvantage that it is too expensive to manufacture
Therefore it is not economical especially in the field of magnetic couplings for series pumps, on the contrary, this type of ceramic gap pot is usually only used in special processing, in order to live up to the high price of this type of gap pot

Embodiment Construction

[0028] figure 1 A perspective view showing the structure of the magnetic coupler 1 of the invention on the one hand, and a partially assembled state of the magnetic coupler 1 on the other hand. The magnetic coupler 1 includes the following main components:

[0029] An inner rotor 2 , an outer rotor 3 , both equipped with corresponding magnets 4 , 5 , and a slotted pot 6 . The slot tank 6 has a flange 7 and a closed bottom 8 . The tubular section 6 ′ extending between the base 8 and the flange 7 is here positioned in the air gap 9 , 9 ′ between the magnets 4 , 5 with a minimum gap (+ / - 0.1 mm). According to the invention, the slot tank 6 is made of borosilicate glass, which is particularly resistant to chemical materials and pressure, temperature fluctuations and has a size of less than 4×10 -6 / K coefficient of thermal expansion. When installed, the motor side M and the pump side P are exposed. On the motor side, threaded holes 10 are introduced in the outer rotor, on whi...

Abstract

The present invention relates to a magnetic coupler, comprising at least an inner rotor, an outer rotor and a gap pot made of a non-conductive material arranged between the inner rotor and the outer rotor, characterized in that the gap pot is only made of Made of glass.

Description

technical field [0001] The invention relates to a magnetic coupler according to the preamble of the first claim. Background technique [0002] Slot pots commonly used in magnetic couplers are made of metals of different alloy compositions, composite materials, ceramic materials, glass fibers or carbon fibers. [0003] The problem with metallic slot pots is that large eddy current losses and the associated high temperatures can lead to very large power losses in the region of the magnetic coupler. This results in a motor with considerable power. [0004] Synthetic slot tanks have the disadvantage that they have only a low temperature and pressure resistance. [0005] A slot pot made of ceramic material has the advantage that eddy current losses do not occur, so that high temperatures cannot occur. But it has the big disadvantage that it is prohibitively expensive to manufacture. It is therefore not economical in the field of magnetic couplers especially for series pumps, ...
