The aim of this thesis is to develop an electromagnetic linear actuator integrated with position sensing and braking function. Designing the mechanism elements, the entire system structure and controlling circuit system based on the actuating principle and the clamping form we choose and studying itsmovement modal and characteristicsaccording to the results of prototype experiments and finite element method analysis is the process of this thesis. The finals of this thesis is the performance testing, and the stepping stroke of the actuator is influenced directly by driving voltage according to the results of testing. The positioning precision is influenced by minimum stepping stroke and heat effect of coils. There are several characteristics which differentiate the multi-function integration electromagnetic linear actuatorfrom its traditional counterparts, and those are: (1) integrating actuating, position sensoring, and braking function in an actuator, (2) position fixing without energy supply, (3) infinitely variable stepping stroke without the smallest stepping stroke limitation theoretically, and (4) changing movement modal easily by changing the controlling program etc.
