Abstract:

A voice coil actuator (VCA) was designed which can implement two degrees of freedom moving. The structure and work principle were introduced. Magnetic circuit analysis in theory and model simulation were implemented and the difference between them was less than 10%, which verified the correctness of theory analysis. Lastly, the designed device was manufactured and tested. The results showed that the VCA could satisfy the requirement to high speed and high frequency response.

Key words: voice coil actuator (VCA), two degrees of freedom moving, magnetic circuit analysis, FEM simulation
