This invention provides an active heating method and system for a two-dimensional turntable servo mechanism, belonging to the field of laser communication technology. The method includes acquiring the feedback temperature and motor torque of the azimuth or pitch axis; when the motor torque is zero and the difference between the feedback temperature and the preset temperature is outside the preset temperature range, heating is performed by determining a first heating power based on the first d-axis current and the electrical control angle; when the motor torque is not zero and the difference between the feedback temperature and the preset temperature is outside the preset temperature range, heating is performed by determining a second heating power based on the second d-axis current and the q-axis current, until the temperature difference returns to the preset range and heating stops. This invention utilizes the heat generated by the motor's own current to replace external heating devices, achieving uniform heating from within, effectively reducing deformation and frictional torque fluctuations in key moving parts caused by temperature gradients, and improving the turning table's pointing accuracy and thermal stability under extreme temperature changes.
