Tachometer generator

Overview

The tachometer generator adopts a split structure, consisting of three parts: rotor assembly, stator assembly and brush holder assembly.

Main functions

       The tachometer generator is a miniature special generator used to detect speed. Its output voltage is proportional to the speed. The rotor of the tachometer generator is coaxially connected with the radar antenna transmission shaft. By detecting the output voltage of the tachometer generator, the speed of the tachometer generator can be obtained, which is the speed of the antenna transmission shaft. Given that the speed ratio between the antenna transmission shaft and the antenna is 1:27, the speed of the radar antenna can be calculated.
