摘要
针对用户对仪表(尤其是油量表)性能要求的提高,介绍在汽车仪表设计中动磁式机芯产生回差的原因及影响因素,提出解决回差的方法,使之更适合低成本电子仪表的设计。
In view of the customers＇ higher requirements for the performance of instruments （fuel gauge especially）, the author introduces the causes and influence factors of the return difference occurring in movingmagnet movements in automobile instrument design, and presents the solution to make it more suitable for the design of low-cost electronic instruments.
