According to the warmup process and jacking oil pump system of high power high speed synchronous motor in long distance pipeline, the unit warmup process was tested and analyzed. The warmup process was not highly correlated with the vibration value of the synchronous motor near the critical speed point, and the warmup time could be reduced or cancelled. The synchronous motor jacking oil pump system was tested, and the changes of the synchronous motor vibration, temperature, start stop time, etc. when the jacking pump was cancelled were analyzed. The results showed that the chain stop pump speed of the jacking oil pump could be reduced.
