The invention discloses an electromechanical direct drive system, and particularly relates to the technical field of new energy automobiles, the electromechanical direct drive system comprises an engine, one end of the engine is mechanically connected with a power generation module, the connecting end of the power generation module is connected with an electric drive module, a discharging module and a charging module, and the connecting ends of the discharging module and the charging module are jointly connected with a peak power energy storage module. Wherein the power generation module is an excitation direct-current generator, the electric drive module is an excitation direct-current drive motor, and the peak power energy storage module is a super capacitor or a high-rate discharge rechargeable battery. According to the invention, the previous design is improved, and the engine is always at the highest efficiency point of the running rotating speed through the electromechanical direct-drive system and the electronic speed controller; the excitation direct-current generator and the excitation direct-current driver maintain the highest comprehensive efficiency through excitation current adjustment, and the comprehensive efficiency is about 95%; the peak power is greatly expanded by using the super capacitor; the rated operating power is mainly supplied by the engine or is assisted by other energy source equipment.
