| Modeling-Simulation and Analysis of MEMS Microsensing Membrane |
Electrostatic actuation, commonly used in MEMS, is based on the electrostatic fields and the forces they generate on the structures.
The deformation of electrodes, caused by the electrostatic forces, is the main concern in electromechanical actuators such as RF micro-switches, comb-drives and Pressure sensors.
In fact, an electric field is created between two electrodes by applying a potential difference which generates electrostatic forces that will be main cause of deflection.
This technology has been used in many industries, such as automotive and bio-medical, due to its light weight, compact size, low-power consumption, and durability.
EMS Simulation software from EMWorks [1]; has been used to study a resultant deflection of a membrane under an applied dc voltage; the Electrostatic analysis type with coupling to structural has been used to achieve such goal. In the carried out analysis, the electric force has been considered and the gravity acceleration has been ignored.

| Challenges of Modeling Spherical Electric Motors |
|
|
|
| |
| |
| Electric motors typically move in one degree of freedom, e.g., around one axis or along one direction.? On the other hand, a spherical motor is a multi-axes electric machine capable of moving a part or a structure in more than one direction using only one motor. This type of motors has witnessed a significant increase in demand due to the emergence of new applications that require large tilt angles, multi-degrees of freedom (MDOF) motion, and more uniform fluxes; such applications include automotive powertrains, biomedical instrumentations, and oil and gas robots. Unfortunately, designing spherical motors is an uncharted territory for most motor and actuator companies. Such an undertaking necessitates not only an experienced engineer with a deep understanding of motor design, but also a state-of-art motor simulation software capable of handling MDOF motion. Most commercial electromagnetic and motor simulation software packages can handle only one degree of freedom, except EMS. Thanks to the coupling to SolidWorks Motion, EMS is capable of handling MDOF motion.
