Abstract

Provided are an SEA, a method of controlling the SEA and a system using the same. The SEA includes a motor-side rotation unit coupled to a driving motor and rotated by rotatory power of the driving motor, a load-side rotation unit coupled to the motor-side rotation unit to transfer the rotatory power of the driving motor to a load, and at least one pair of elastic members provided in spaces between the motor-side rotation unit and the load-side rotation unit. A frame having accommodation spaces to which the pair of elastic members is fixed is formed in any one of the motor-side rotation unit and the load-side rotation unit.
