Drive Characteristics Analysis for Stackable Electromagnetic Actuator

Abstract

　Recently, ultra-compact electromagnetic actuators are used in high temperature fields, and special applications in industry. However, the size and required thrust differ depending on the purpose and application used, therefore it is necessary to redesign an electromagnetic actuator suitable for each application. In addition, there are problems such as demagnetization of a permanent magnet used for an actuator in a high temperature field and generation of a very large EMF (electromagnetic force) by coils. Therefore, I design a stackable electromagnetic linear actuator and various the characteristics by electromagnetic analysis.
