In this paper, a method of deep learning is built to reduce the needed time on performance analyze and optimization of permanent magnet synchronous motor (PMSM). The analysis of the electromagnetic speed, torque and efficiency of PMSM is carried on with Finite Element Method (FEM), which is 8 pole-pairs, 48 stator slots and 195mm of stator external diameter. FEM model of PMSM is established, and the...
Magnetic properties of ferromagnetic materials are important features in power transformer and electrical machine design and manufacture, which should be measured accurately. The measurement data under a small frequency range is given by proposed methods. However, the data at high-frequency needs to be investigated more deeply. A novel 2-D magnetic properties tester for ferromagnetic material specimen...
The rotating magnetic properties of nanocrystalline materials at high frequencies play an important role in design and optimization of high frequency transformers with large capacity and high performance. In this paper, a novel high frequency rotating magnetic properties tester is designed, which is applied to measure the high frequency rotating magnetic properties of nanocrystalline materials. By...
When analyzing magnetic field distribution of the permanent magnets during the magnetizing process, it is important to couple the system equations of analysis method to the equation for the electric circuit. In this paper, the equations to calculate the residual flux distribution of permanent magnets using the $T\text{-}\Omega$ method taking into account the magnetizing process that uses the discharge...
Computation software package realizes modularity design of modeling for new high performance materials applied to electrical engineering for the first time. Using fuzzy neural networks control (FNNC), the assumption of self-learning function is realized. This software package provides theoretical basis and device performance simulation methods for these materials application. In this paper, taking...
This paper presents a magnetomechanical hysteresis model for a giant magnetostrictive device. In the model, the magnetization is characterized by the Jiles-Atherton model and the improved magnetomechanical effect model, the magnetic force is modeled by an equivalent magnetic circuit. In order to obtain optimal parameters of the model, a genetic algorithm is used. Comparisons between the experimental...
