PURPOSE: A motor driven active vibration control apparatus is provided to generate thrust force to buffer the vibration generated in a damping target object by using a motor. CONSTITUTION: A motor driven active vibration control apparatus comprises a base(10), a damping plate(20), one or more springs(30), an actuator, a vibration sensor(50), and a control unit. A load member is installed on the damping plate. The springs support the damping plate. The actuator applies thrust force to the damping plate. The actuator is composed of a motor(40) and a crank unit(41). The motor generates torque. The crank unit applies straight force to the damping plate by using the torque of the motor. The vibration sensor senses the vibration of the damping plate. The control unit controls the operation of the actuator based on the sensed result.
