The invention relates to an electronic mechanical driving mechanism which comprises a direct-current torque motor, an encoder, an electromagnetic brake, a planetary gear, a box body, a front cover, arear cover, a dustproof cover and the like. An encoder stator part is fixed on the motor rear cover, and an encoder rotor part is locked on a motor shaft through a self-locking mechanism; an electromagnetic brake stator is fixed on the motor rear cover, and a brake rotor transmits power to the motor shaft through a flat key; the output end of the motor shaft is fixed to a sun gear in the planetarygear, a gear ring in the planetary gear is fixed to the motor front cover, and the planetary gear outputs braking force through a planet carrier. The electronic mechanical driving mechanism is compact in structure, convenient to install and easy to maintain, has a bidirectional braking function, can monitor the rotating angle of the motor shaft in real time, and is high in adjusting precision, safe and reliable. When a fault occurs, an operator can rotate a hexagonal reset screw rod to carry out emergency mechanical relief.
