Abstract：Based on the structure and control theory of the spin missile actuator and considering the characteristic of the correction fuze, a electromechanical actuator is designed.
A control method of the electromechanical actuator is discussed by the actuator work theory
researched. Simulation results indicate that the designed electromechanical actuator, which is
driven by a brushless DC motor and is forced by the alternate loading, can ensure the
accuracy of phase compensation and rotation synchronization.
