“…Niski poziom drgań, hałasu, wysoka sprawność oraz bezobsługowość stawiają taki przetwornik jako element turbin wiatrowych, czy podwodnych turbin pływowych. Naturalne zabezpieczenie przed przeciążeniem jakie oferuje przekładnia magnetyczna, to dodatkowa zaleta, bardzo istotna w aplikacjach przemysłowych podatnych na częste przeciążenia [1][2][3][4][5][6][7][8][9][10].…”

Optymalizacja pasywnej przekładni magnetycznej Streszczenie. Praca zawiera wybrane wyniki badań optymalizacyjnych dla pasywnej przekładni magnetycznej. W obliczeniach zastosowano algorytm ewolucyjny współpracujący z biblioteką obliczeń równoległych wsparty dodatkowo bazą danych. Obliczenia polowe wykonano za pomocą dwuwymiarowej metody elementów skończonych. Badania przeprowadzone dla kilku wariantów funkcji celu wskazały wartości parametrów konstrukcyjnych, dla których gęstość przenoszonego momentu jest bliska 100kNm/m 3 .

“…It is hard to determine the air-gap flux paths and the permeance calculations precisely [10]. In order to overcome the above problem, equivalent magnetic network (EMN) was developed in both 2-D magnetic circuit machines [11]- [14] and 3-D magnetic circuit machines [15]. However, a large number of mesh elements are needed to fit the topology of the electric machines with large size and irregular structure, which lead to serious computational cost especially the 3-D magnetic circuit machines.…”

In this paper, a strong coupling between magnetic and electric phenomena is provided allowing to have an accurate and high-speed coupled model. A coupled circuit and magnetic model for an E-core transverse flux permanent magnet linear motor (TFPMLM) is proposed, which has an advantage linked to reducing time computing more than ten times when compared to 3-D finite-element model (FEM). Firstly, a multi-plane flexible-mesh nonlinear equivalent magnetic network (EMN) model is proposed to improve the computation efficiency as well as the high precision of the magnetic model. And a new method to define the converged iterative process is presented to further decrease the computing time. Secondly, the magnetic circuit and electric circuit are normalized into a solution matrix by introducing controlled sources and discretization methods which forms the coupled model. Then, the magnetic flux in the magnetic circuits and the current in the electric circuits are obtained simultaneously for each time step. The characteristics such as the air-gap flux density distribution, output thrust force waveforms and the phase currents are analyzed by the proposed coupled model. The modeling approach is approved by comparison with the 3-D FEM model. Finally, the proposed model is validated through the experimental setup with the machine prototype. INDEX TERMS Coupled model, electric circuit, equivalent magnetic network (EMN), linear motor, transverse flux.

“…However, the saturation effect is neglected, which constitutes the main limitation of the analytical models. In order to account for the nonlinear B-H characteristic of the iron, semi-analytical models based on the magnetic equivalent circuits can be used [21], [22]. These models have been widely developed for electric machines [23]- [29] but less for magnetic gears.…”

This paper presents a nonlinear adaptive magnetic equivalent circuit (MEC) of a coaxial magnetic gear (MG). High speed (HS) and low speed (LS) rotors are equipped with surface mounted PMs. The stationary ring (SR) located between the rotors is constituted by magnetic iron pieces which create the flux modulation. Using the MEC, the magnetic flux density is calculated in the different parts of the MG, as well as the stall torque. In order to evaluate the reliability of the proposed model, the results are compared to 2-D finite-element analysis (FEA).
