The fast response and stable output of the torque are key techniques of electric screw press. Working principle of the electric screw press with gear transmission was introduced, basic principle of flux vector control was discussed, then the driven solutions of electric screw press by permanent magnet synchronous motor of flux vector control were proposed. The superior performance of torque control was shown through experiments. Motor starting current and temperature rising were effectively controlled, which made the electric screw press achieve long-term stable operation. This research has been applied successfully in practical work.
