A dual-axis pointing mirror with moving-magnet actuation

Nico de Rooij, Caglar Ataman, Wilfried Noell, Sébastien Lani

A large-aperture and large-angle MEMS-based 2D pointing mirror is presented. The device is electromagnetically actuated by a moving-magnet/stationary-coil pair and potentially suited for high power laser beam shaping and beam pointing applications, such as ...

Slotless Permanent-Magnet Machines: General Analytical Magnetic Field Calculation

Yves Perriard, Pierre-Daniel Pfister

This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without negle ...

Vibration modes of the brushless DC motor

Sylvain Candolfi

The objective of this project is to determine in an analytical way the modes of vibration of the stator of a brushless DC motor. The knowledge of these modes is important. Once the vibration modes are determined we can avoid their excitation and thus reduc ...
