Design and manufacturing of an electrostatic MEMS relay for high power applications Open
This paper addresses the design and manufacturing of a crab-leg based MEMS relay for a high power application. Thanks to a contact resistance lower than 100 mΩ, the relay can hold a current in the order of magnitude of an Ampere without fu…

Current Control Strategy for Dynamic Winding Reconfiguration of Slotless Brushless DC Motors Open
Depending on the winding configuration, the intrinsic characteristic of a motor differs. By reconfiguring the winding, it becomes possible to increase the torque–speed limitation of a motor. Current proposed methodologies for dynamically r…

Integrated approach for auto-adaptive synchronous motor winding Open
The intrinsic characteristic of a permanent magnet synchronous motor is defined by its internal dimensions, its material properties, as well as the power supply used in conjunction with the motor. When an extended operating range is desire…

Modeling, Design, and Manufacturing of Microfabricated Coils With High Inductance Density Open
This paper addresses the design and manufacturing of small scale square planar coils with inductance densities ranging from 2 to 19 miH.mm-2. The design strategy is based on both analytic formulas and finite element method (FEM). Two diffe…

Dynamic winding reconfiguration of a brushless DC motor Open
The torque transient behavior during winding reconfiguration of a brushless motor is investigated in order to suppress torque interruptions or jolts. This reconfiguration changes the intrinsic torque-speed characteristic of the motor. A si…

Electrostatically actuated MEMs relay for high power applications Open
In this paper, a MEMs relay for high power application is investigated. This relay has to hold a current of the order of magnitude of the Ampere and is subject to harsh environment such as high temperature or vibrations which can lead to a…
