The simulation of a gas insulated switch at 50 Hz is simulated with the low frequency solver in CST EM STUDIO™ (CST EMS). A Pro/E® model is imported, appropriate three-phased sources defined and a simulation performed to obtain the current distributions in the three phase conductors. Read full article..

CST EM STUDIO™ (CST EMS) is applied to the simulation of a magnetic injection valve by use of its non-linear magnetostatic solver. The aim of the simulation is to obtain the force on the valve armature as a function of the air gap between the armature and the main valve housing. Using the powerful and easy-to-use parameterisation features in CST EMS, a familly of force curves as functions of gap and excitation current can be easily generated. Read full article..

CST EM STUDIO™ can be used to obtain the force-current characteristics of a magnetic brake. The Magnetostatic Solver is ideal for such an application. Read full article..

This article summarises the setup and simulation of a small DC machine (50 W; 6000 rpm; 14 V) with ferromagnetic material, a double-layer wave rotor winding (Cu) and ceramic magnets on the stator side. CST EM STUDIO™ (CST EMS) features such as tetrahedral meshing, non-linear materials, easy-to-use parameterisation of geometry, rotor angles and armature currents are all applied to the simulation of the motor.
