Temperature field control of electromechanical system with constant temperature is one of the important factors that affects the accuracy of the system. Traditional ways of temperature detection cost a lot but have low responding sensitivity. To solve this problem, temperature field simulation using numerical simulation was done toward the electromechanical system, and the platform temperature field distribution as well as the process of the platform reaching the steady-state was analyzed. The research shows that the system temperature observing parameters are all within normal range and the temperature control structure is rational. In all, the research achievements have some engineering and theoretical values in improving the design of temperature control device and system accuracy.
