自动天线电路原理及动力分析

Circuit Principle and Power Analysis of Automatic Antenna

介绍自动天线的结构及电路原理,计算卷曲拉线的长度,对正常运转时的总负载力矩及电动机堵转时的最大力矩进行动力分析。证明各结构参数能保证天线杆进行自动伸缩的功能。

The construction and circuit principle of automatic antenna, legth calculation of the rolling wire drawing, and the power analysis of overall load moment at the normal operation and the maximum moment during the moter braking are introduced. Thus, it is showed that each constructural parameter can assure the automatic extension of antenna trimmer.
