Analysis and Application of the Influence of Magnetic Material and Magnetic Gap on Electromagnetic Actuator

Abstract

The impact of the actuator is examined in light of the properties of various materials. The features of the N48 material are examined when the N48 permanent magnet material is chosen. A novel magnetic steel construction for an electromagnetic actuator is built after analysis of the air gap structure. The functionality and nonlinear issues of the electromagnetic actuator are investigated in accordance with the properties of the materials and constructions. The link between electromagnetic output and current and frequency is investigated and determined using theoretical analysis, finite element analysis, and real test. The magnetic flux density distribution, electromagnetic dynamic response, current frequency relationship, and surface skin effect are derived using the electromagnetic simulation model built in COMSOL. Time domain simulation is used to determine the electromagnetic actuator’s static linearity. Simulation in a steady state is used to determine the operating linearity of an electromagnetic actuator. To confirm the accuracy of the theoretical and simulation results, the electromagnetic actuator prototype is put to the test. The simulation results demonstrate the high linearity and good performance of the electromagnetic actuator, with an average static linearity of 97.24%. To confirm the validity of the theory and simulation, an actual test is conducted on the structural prototype. The outcomes can not only serve as a guide for the best design of electromagnetic actuators but can also demonstrate the benefits and potential uses of various materials used in actuator construction.
