Optimization Design and Characteristic Analysis of the New Magnetic Steel Structure Electromagnetic Actuator

Abstract

New energy materials refer to the key materials used in the transformation and utilization of new energy and the development of new energy technologies. The soft magnetic has high saturation magnetic induction intensity, good high-frequency magnetic properties, low loss and low cost, and is widely used. In this paper, according to the high magnetic properties of soft magnetic materials, the static and dynamic performance of the electromagnetic actuator under the new magnetic steel structure is studied. Based on the finite element method, the AC / DC module in COMSOL is used to study and simulate the performance of electromagnetic actuator. The relationship between electromagnetic actuator output and current and frequency under steady state is studied, and the influence of surface skin effect is simulated. The static linearity of electromagnetic actuator is observed by simulation in time domain; Simulation analysis of linearity in steady state. The relationship between the output of the actuator and the current and frequency is obtained by the simulated two-dimensional line diagram, and the distribution of the skin effect inside the electromagnetic actuator is obtained by the surface diagram. The static working simulation in time domain obtains the static linearity, and the simulation in steady state obtains the linearity in working state. The output performance of the electromagnetic actuator under the new magnetic steel structure is improved, with an increase rate of 47.3%, and its skin effect is evenly distributed. The static linearity increases by 63% and the dynamic linearity increases on average. According to the results of the research and simulation, it has a theoretical reference value for the promotion and application of magnetic energy, as well as the use of electromagnetic actuators for motor structure optimization and efficient matching.
