This research proposes to change oil-pressure system to electro-mechanical system which is adapted thrust-vector control(TVC) system. The goal is to convert the existing hydraulic system of launchers to electro-mechanical system. And this paper, as part of project, studies FEM design of motor in electromagnetic system and EMF-Thermal coupled analysis was performed through simulation. In addition, this paper attempts to demonstrate the thermal reliability of motor operation in space through suggested limits of its hypotheses. So this paper focuses on lightening motor and the heat problem which is most common problem in motor operation.
