Magnetostatics

This article is concerned with the application of CST EMS to the design and analysis of a tubular permanent magnet linear generator. Demonstrated is the proposal of a possible application of tubular generator, the analysis of a system definition in order to define a first optimization criteria and 3D electromagnetic simulation based on finite inegration method to carry out a parametric analysis of the machine behavior. This is a summary of the work carried out by Andrea Pirisi, G. Gruosso, Riccardo E. Zich of the Politecnico di Milano, Italy. Read full article..

This work presents the 3D magnetostatic numerical analysis based on Finite Integration Technique applied to the design of magneto-inductive devices for the Non Destructive Testing (NDT) of ferromagnetic ropes. The problem is characterised by several design aspects and by the high saturation level reached in the device core and in the rope under testing. CST EM STUDIO® was used for the virtual prototyping which entailed the the optimisation of permanent dimensions using 3D non-linear magnetostatic optimisation. Measured versus simulated results are presented. Read full article..

Automotive suppliers were among the first to incorporate numerical simulation in the product development process to reduce development cycles and minimize the production costs. Electromagnetic field simulation such as provided by CST EM STUDIO® (CST EMS) helps the engineers to accelerate product development. This article shows the application of CST EMS to the simulation of a stepper motor found in speedometer applications. Read full article..

This article shows a common approach to the simulation of electromechanical problems. A set of 3D electromagnetic field simulations using CST EM STUDIO® (CST EMS) are carried out on a linear actuator in order to obtain its electromagnetic characteristics for use in Simulink® where both the electrical and mechanical behaviour can be simulated.

Electron guns are the starting point of every charged particle application. There the DC energy is translated into an extracted beam which later on interacts with all kinds of RF structures. The design and analysis of an electron gun can be performed with the tracking code of CST PARTICLE STUDIO® as shown in this article. 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..

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.
