摘要
Abstract
A new type of rotary electromagnetic actuator with permanent magnet ( PM) was designed. Based on the polarity characteristics of PM, a couple of coils in diagonal direction are designed. And a flux guide path is designed to optimize the magnetic circuit. The electromagnetic system and the contact system are designed seperately, which can achieve a high level maximum space utilization. In order to study the characteristic of PM, the PM is divided into several sub-sections. The migration analysis of the working point based on analytic model is carried on for the selection of PM, and the precise static characteristics of the actuator is analyzed by the finite element model. The prototype actuator was assembled and tested, and the advantages of fast conversion speed and high reliability were verified by the test.关键词
