| Abstract: |
| The factors of antenna drive system affecting motor current characteri
stics are analysed. The standards of motor current characteristics, for antenna
normally tracking the satellite, are proposed. The motor current below 6A is i
n the normal range. Motor current analysis (MCA) is applied to the fault diagno
sis of antenna drive system for periodic failure, damped increasing failure and
fatal failure. At the same time, the impact of the three types of fault of drive
system on tracking performance is analyzed. The results show that MCA can be
used to pre-judge the fault of antenna drive system, which can effectively
avoid fatal failure, and ensure the antenna to track satellite in good condi
tion. |
