Abstract

The ideal electromagnetic actuator for an adaptive secondary mirror must be compact and able to deliver a large force with a small power dissipation, in spite of the geometric constraints. The magnetic circuit, including auxiliary components and coils, has been entirely modeled, in order to optimize the efficiency of the actuator, regarded as a linear motor. Forces and efficiencies have been computed in various geometric configurations, among which the final layout was chosen.
