Abstract
In this paper the influence of basic design
parameters (proportionality coefficient β and permanent
magnets height h) on the mechanical torque for cylindrical
magnetic coupler with rounded permanent magnets is
researched. Such cylindrical magnetic couplers are often used in
pumps and liquid mixers. At the beginning the design parameters
and their relevance are explained. The mechanical torque is
calculated applying the software QuickField. In the data analysis
and for the coupler comparison the division of maximal
mechanical torque on volume is taken as the main characteristic.
Because of the planned optimization for the calculated variants
there were synthesized few formulas, from which the most
suitable were found (for all researched design parameters’
ranges). The formulas are synthesized using a program, which is
created by Oskars Onzevs. The program for the formula
synthesis is based on regression models, and the basic principles
of it are explained. All the calculations for experimental and
formula data are made for magnetic coupler’s design with one
pole pair number p that is equal to three
