This paper describes the design of small-sized and high thrust electromagnetic actuator, and the optimization of the mover aimed at the lightweight of the mover. The proposed electromagnetic actuator is used for the hotmelt applicator. The stackable electromagnetic actuator has been designed so that the electromagnetic actuators with various characteristics can be configured because the hotmelt has different properties for each main component. Moreover, in order to improve the characteristics of the electromagnetic actuator, it is considered useful to reduce the mass of the mover according to the equation of motion. In this paper, the permanent magnet volume has been reduced and resin has been interposed as a spacer to reduce the weight on the mover. As a result, the proposed model can obtain the same thrust as the conventional model and the response can be improved.
