“…As the doubled-sided linear motor has a symmetric structure along the y-axis, only one side is selected as the analysis region. To simplify, some assumptions are made, as follows [9][10][11][12] Figure 2 shows the analytical model of the PMLSM for the magnetic field analysis. The sources of the permanent magnet array are expressed in the form of a Fourier series, so that higher order harmonics can be taken into consideration.…”

Abstract:In this paper, a novel ironless linear synchronous motor with a cooling system is proposed. Firstly, the topology of this ironless linear synchronous motor with a cooling system is introduced. Flux density in the cooling system is obtained analytically by the separation of variables method according to the boundary conditions. The eddy current braking force induced by the cooling system is calculated and validated by finite element method. Then, the influence of the motor parameters on the eddy current braking force is investigated. At last, a prototype is manufactured and some experiments are carried out with the prototype. The experiment results are validated by finite element analyzed results.

“…A new flux Φ (k) i and new flux density B (k) i of the stator (i.e., AT 0 ) can be derived by using (13) and (14) after the initial permeability of the stator is applied to solve (11) can be written as (15). The corresponding relative permeability μ (k) i can be obtained as (16).…”

“…Approximatively, these PMs can be considered as rectangle sources. Also, the surface-mounted PM (SPM) and the interior PM machines were analyzed by using LPMC method in [16][17][18][19][20][21][22]. The magnetization direction of their PMs is radial or parallel.…”

Abstract-Permanent-magnets (PMs) with tangential and parallel magnetization directions are combined in the Halbach PM (HPM) machine, which can offer high performances. However, the existing lumped parameter magnetic circuit (LPMC) model can only calculate one PM magnetization direction, namely either tangential direction or parallel direction. The key of this paper is to propose a method to divide and establish equivalent magnetic motive force (MMF) for HPM machine with both tangential and parallel magnetizations. Then, a LPMC model, using equivalent MMF, is developed to predict the electromagnetic performances for a four-phase HPM machine. In order to verify the effectiveness of the proposed LPMC model, a 6-pole/8-slot 15 kW HPM prototype is built. The comparative results of the proposed LPMC model, two-dimensional (2D) FEM and the experiments verify the effectiveness of the proposed LPMC model.

“…Thus, in the world scientific and technical literature, much attention has been paid to the development of theoretical and metho do lo gi cal approaches to solving the problems arising when de veloping mathematical models of elec tric objects. In these approaches, efforts are made to take the construction of objects into account to as great an extent as possible and apply real physical laws of electromagnetic phe nomena occurring in the device media [1][2][3][4][5][6][7][8][9][10][11][12]. One of the more advanced strategies for successfully tackling this problem is to develop mathematical models of electric objects exclusively based on the theory of electromagnetic fields.…”
