Abstract: A new structure of electromechanical actuator was proposed according to the control princi?ple that the trajectory correction of rolling projectile requires. The kinetic model was made, and the practicability of the structure was analyzed through an example. The analyzed result indicates that the load is very little, the structure is simple and the action is reliable. It can drive four rudder faces by on?ly one electromotor and is very suitable to rolling projectile.
