摘要
从节能、省材、安全的角度,就起重永磁吸盘设计制造中有关永磁材料与导磁材料选用、磁路设计组合、永磁体的充退磁方法等问题进行了讨论,着重介绍了用电脉冲充退磁的铝镍钴永磁、钕铁硼永磁或二者组合式的起重永磁吸盘的结构设计、RLC电路在脉冲充退磁技术中的应用,及如何合理选用参数以实现起重永磁吸盘的小自重、低成本及长寿命。
This paper discusses selection of permanent and soft magnetic materials, magnetic circuit design, and permanent magnet magnetization and demagnetization from these aspects of energy - saving, material - saving and safety. The main description is structural design of Al NiCo, NdFeB and Al NiCo--NdFeB combined permanent lifting magnets, application of RLC circuit in electric pulse demagnetization and how to select parameters to make sure that the lifting magnets designed features low weight, low cost and long life.
