| Abstract |
As well known, linear electrical motors and actuators are electromagnetic devices used to produce unidirectional or oscillatory short-stroke motion, directly without mechanical linkages. The project of a classic electrical machine - generator, motor or actuator, - can be made by using either analytical or numerical methods. However, at present much of the new existing small actuators present a variable geometry. Thus, the analytical design of this class of actuators must be accomplished with numerical methods based on finite elements in view to optimize the electromagnetic and mechanical geometry. The subject of this paper is the finite-element analysis of a prototype of a single-sided linear switched reluctance actuator. |
