“…FEM is an efficient and accurate means to calculate magnetic field, taking full account of nonlinearity of iron material and induced currents in electrically conducting parts [18][19][20]. However, it is time consuming and cannot give much insight into design parameters [21]. Magnetic equivalent circuit can mainly be classified into lumped equivalent circuit and mesh-based one.…”

Abstract-Permanent magnet (PM) array affects flux field distribution of electromagnetic linear machines significantly. A novel dual Halbach array is proposed in this paper to enhance flux density in air gap, and thus to improve output performance of linear machines. Magnetic field in three-dimensional (3D) space of a tubular linear machine with dual Halbach array is formulated based on Laplace's and Poisson's equations. Numerical result from finite element method is employed to simulate and observe the flux distribution in the machine. A research prototype and a testbed are developed, and experiments are conducted to validate the analytical models. The study is useful for analysis and design optimization of electromagnetic linear machines.

Abstract-The Remote Field Eddy Current (RFEC) method is widely used to inspect both ferrous and nonferrous metal tubes when internal access is the only possible way of inspection. An axisymmetric quasi-analytical model is presented in this paper in order to simulate the behavior of a RFEC system during its operation. The proposed model, based on the application of the Fourier Transform in space, is able to take into account the finite length of the excitation coil, fed by an AC current, and the relative movement between the RFEC system and the wall tube. Numerical simulations based on integral formulations and experimental measurements were used to validate the proposed quasi-analytical model.

Abstract-In this paper a novel evolutionary algorithm is used for the optimization of the performance of a magnetorheological (MR) device, capable to transmit torque between two shafts and powered by a system of Permanent Magnets (PMs). The stochastic, evolutionary, global optimization algorithm is based on a modified version of the self-organizing map. It uses a dedicated simplified analytical model of the device, developed in order to obtain a fast and accurate evaluation of the torque. Then, by means this model, the cost function to find the optimal parameters of the device is defined. Once the optimal parameters are identified, the performance of the proposed device is simulated by means of a FEM software. The results in terms of magnetic flux density inside the fluid, the transmissible torque and the actuation torque necessary to perform the device activation are discussed. Finally, a preliminary experimental validation of the proposed device is performed.
