Abstract
The purpose of this paper is to analyze and design a new hybrid electromagnetic linear actuator for linear pumps. Solenoid linear actuator is widely used because it occupies small space due to no mechanical energy conversion system. In addition, the energy loss is very low and it has no noise. Conventional solenoid linear actuator, however, has the critical drawback of high power consumption. In this research, we present a new hybrid electromagnetic linear actuator using a permanent magnet in order to reduce power consumption. The enhanced performance of the hybrid linear actuator was verified by dynamic finite element analysis.
