| 講演名 | 2010-11-12 17:15 Study on Zero-Flux Application for Restraining the Remanence of High-DC-power Electromagnet ○Yuan Haiwen・Mi Hanguang・Guo Xin・Liu Yingyi（Beihang Univ.）  EMD2010-125 |

| 抄録 | （和） | High-DC-power electromagnet whose coil voltage is 24V or 48V has been wildly used in the lifting equipment and the braking system of construction machinery. In applications, it works on the switching state condition. The armature drives objective as schedule when turn on power and when shut off power, the armature should be released immediately. But in applications, many factors such as material properties, processing technic and design technic result that there is too much remanence left after the power shut off and the armature cannot be released as required. This situation can be very serious in applications of High-DC-power Electromagnet. Light of above, the paper proposes a new method to restrain the remanence. The method is based on feedback control. A feedback controller is embedded in magnetic circuit of electromagnet. If there is much remanence left when the power of electromagnet shut off, the controller will generate the excitation current which is against the direction of remanence current. The Zero-Flux can be reached based on this method and the armature will be released as requirement. Detail analysis is given in this paper. Necessary simulation and theoretical analysis is done. Then the experimental circuit is designed and some experiment is done to test and verify this method. At last, the method is used in application. The application result indicates that the method restrains the remanence of High-DC-power electromagnet and the armature is released immediately. So the reliability has been greatly improved. Furthermore, the method can be reference in industry applications. |
