To achieve higher performance in spark-ignition engines, it is necessary to further improve combustion conditions. For this purpose, stepless control of the intake and exhaust valves in accordance with engine speed is required. Our research group has been continuously studying the electromagnetic drive valve system using linear actuators. In this report, we have designed a linear actuator with a dual Halbach array of permanent magnets in the stator in order to further increase the thrust of the actuator. The thrust characteristics of the proposed model were investigated by changing the applied current using electromagnetic field analysis based on the finite element method. The results of the analysis showed that changing the applied current affected the thrust characteristics of the actuator.
