The purpose of this paper is to analyze and design an electromagnetic linear actuator of active linear absorber (ALA) system for vehicle vibration reduction. An ALA system is one of the effective methods to reduce vibration generated by engine. It generates the counter force to cancel abnormal vibration generated when the variable cylinder is working. So, to reduce the engine vibration efficiently,...
This paper presents the new design of flat-coil actuator. Novel shorted turn and copper center pole are placed into existing design in order to reduce the inductance of coil and improve the initial response. Dynamic finite element analysis using commercial electromagnetic solver “MAXWELL” is performed to simulate the improvement of dynamic characteristics, especially fast initial response.
The purpose of this paper is to analyze and design an electromagnetic linear actuator for linear pump. Solenoid linear actuator is widely used because it occupies small space: it has no mechanical energy conversion system. In addition, the energy loss is very low and it makes no noise. Conventional solenoid linear actuator, however, has the critical drawback of high power consumption. In this research,...
