Thanks to simulation, Kampmann engineers are now able to answer questions regarding the internal processes of the system, which are difficult, if not impossible, to study through physical testing.

Analysis of Grounding Performances of a Car Body Using FEM Shell Elements

In the automotive domain, the EMC phenomenon of the current return occurs over a wide frequency band due to the fact that the paths followed by the current are very different between the lowest frequencies (a few Hz) and medium frequencies(hundreds of kHz).

Checking Remanence Issues with New Hysteresis Model

Remanence is what is left when all current is removed, and there is still some flux density left in the iron core. This is often the case with a close path for flux density, especially in U or E shape devices. To get rid of this effect, it is sometimes useful to add a so-called remanent airgap. This paper explains what we have incorporated into Flux to model this effect due to hysteresis.

Cogging Torque Computation and Mesh for Non-radial Electrical Motors in Flux®

All electrical motor designers know that the computation of cogging torque is a tricky task, particularly in 3D. Indeed, the amplitude of this variable is almost the same as numerical noise. In most cases, conventional mesh methodology is not sufficient and specific methodology must be used. At CEDRAT, thanks to its experience, the application team has developed methodologies to successfully compute cogging torque in most cases. This article presents a specific mesh methodology to compute cogging torque for 3D non-radial electrical motors.

Cogging Torque Computation and Meshing for Radial Electrical Motors in Flux®

All electrical motor designers know that the computation of cogging torque is a tricky task in 3D. Indeed, the amplitude of this quantity is almost the same as the numerical noise. In most cases, a classical meshing methodology is not sufficient and specific methodology must be used. At CEDRAT, the application team, thanks to its experience has developed methodologies to successfully compute cogging torque in most of cases. This article presents a specific meshing methodology to compute cogging torque for 2D and 3D radial electrical machine. It begins with some general recommendation concerning the definition of the geometry in order to facilitate the meshing operation. Then, it presents the specific meshing methodology applied to a 2D SPM motor and to a 3D IPM motor.

Comparative Study of Concentrated and Distributed Winding Using Flux®

The paper presents a comparative study of 3-phase permanent-magnet (PM) synchronous machines (PMSM) with concentrated and distributed windings. The purpose of this study is to identify the machine that gives the better electromagnetic performance (torque, efficiency, back electromotive force…). Two PMSM with concentrated and distributed windings having identical output power, stator and rotor outer diameter, airgap, axial length, are designed. Machine performance of the two machines is compared using finite element analysis (Flux 2D).

Eccentricities Faults in a Rotating Machine Analyzed with Flux®

In the present energy efficiency context of electrical machines, diagnosis of rotating machines is increasingly studied. Designers seek to include the on-line, non-invasive diagnosis and typical signatures of the rotating machines faults in the stator winding currents, torque, leakage magnetic field…etc. Among the rotating machine’s faults, 7 to 10% are located in the rotor and some of these faults are eccentricities. These faults generate electromagnetic torque oscillations: electromagnetic forces acting on the stator, particularly the stator winding, which can accelerate wear of its insulation. Friction between the stator and the rotor is not excluded; this can also have an adverse effect on the bearing. In the literature we often find three types of eccentricities: static, dynamic and mixed. Our Flux 2D/3D/Skew finite element solution can be of considerable help to predict the typical signatures of eccentricities faults and the influence of these defects on the electromagnetic and vibro-acoustic performances of these machines, a very differentiating feature of the software. The purpose of this article is to show the feasibility of the different eccentricities with Flux 2D/3D/Skew thanks to the possibilities offered by mechanical sets.

Eccentricities Faults Magnetic Signature of an Induction Machine Determined with Flux®

In the literature we can find two approaches to make diagnosis: Model approach - a specific method for automation engineers. Depending on the mechanism adopted, we can distinguish three branches in this method: monitoring by observers, by analytical redundancy and by parametric estimation. Signal approach - this approach is based on measurable signals data, such as current, torque, stray flux, noise and vibration, temperature. The principle of this method is to look for frequencies unique to the healthy or fault operation. Faults in electrical rotating machines can induce other phenomena such as noise and vibrations and possibly other faults like friction between the stator and the rotor or accelerated wear of insulations.

FE Steady State Thermal Analysis of Squirrel Cage Induction Motors with Flux®

The thermal analysis of electrical machines and the related fluid dynamic computation, tasks associated with mechanical engineering disciplines, seem to interest electrical engineers less than electromagnetic analysis. But, with increasing requirements to fully exploit new designs and materials, it has more or less become compulsory to analyze the thermal behavior of electrical machines, to the same degree as electromagnetic design.

Finite Elements Method Modeling of Contactless Energy Transfer Systems

Contactless energy transfer (CET) systems are used in many industrial sectors. These include conveyors, trolleys, storage and retrieval units, baggage handling, battery charging stations, mobile phones and medical implants. The energy transfer model is quite similar to a conventional transformer, except for the weak coupling between the primary and secondary windings and partial or non-existent ferromagnetic closing paths. Inductive coupling is commonly used in a range from a few mW to a few hundred kW.

How to Efficiently Design Power Transformers

Nowadays Power Transformers need to optimize their efficiency to make sure a minimum amount of losses are generated from the various physical phenomena. Flux Finite Element studies allow transformer designers to accurately analyze the different losses (Joule losses, iron losses, stray losses) to enhance the performance of their transformers. A few steady-state and transient tests permit determining the electrical and mechanical constraints that the power transformer will have to endure in its life. In addition, thermal studies can complete these analyses to detect and prevent hot spots on the tank or in the windings.

Induction Heating and Forced Cooling Analysis with Flux®

Principle of induction heating and forced cooling (shower): induction heating is the process of heating an electrically conducting object without contact. The flowing of the current through the coil (see Fig.1) generates an alternating magnetic field. This field induces current in the electric conductor (eddy current). The repartition of eddy current depends on the shape of the electric conductor, the frequency, and physical properties of the material used in the electric conductor. In addition to this, the high frequency used in induction heating applications gives rise to a phenomenon called skin effect: all the current is concentrated only on the boundaries.

Regulate Current with User Subroutine Using Groovy Language in Flux®

For Switched Reluctance Motor, a specific command of current is often used with a chopper in order to decrease the current ripple or hysteresis band. We propose to see in this example (see Figure 1) how to implement such a command in Flux using groovy language.

Study of Mounted Surface Permanent Magnet Synchronous Machine Using Flux® Skew

Requirements: rotating electrical machine designers want high-reliability, minimum power losses, maximum power, maximum torque and low mechanical resonance vibration and noise. To meet the needs of electrical machine designers, CEDRAT started developing tools that take Skew into account in 2003. Several improvements have been made to this tool. Skew is usually accounted for by sub-dividing the active length of the machine into several 2D slices. In the latest Skew version of Flux the post processing is directly a full 3D post-processing.

Taking Demagnetization into Account in Permanent Magnets Using Flux®

Materials can be classified according to their magnetic property into two main categories: Soft magnetic materials: which exhibit magnetic properties with the presence of external excitation. Hard magnetic materials: exhibit magnetic properties in the absence of magnetic excitation. Permanent magnets are part of this family.

Tunnel Magnetoresistance (TMR) Angle Sensor Simulation Results

The article presents the main results of magnetostatic 3D simulation using CEDRAT Flux software especially for new TMR angle sensor applications. Such magnetic sensors are deployed today in automotive electronics, as well as in many new industrial, consumer-product, medical, avionics, defence and other applications. Under Flux 3D, several effects of the influence of magnet geometry parameters and mechanical tolerances of sensor positioning were investigated, such as airgaps and tilts effects. The results include optimum solutions useful for TMR, as well as for a wide range of other angle sensor types and applications.

Using CEDRAT’s Tool to Review Thermal Solutions

Nowadays, it is more and more difficult to design electrotechnique devices without considering thermal stress. In more and more applications (electric vehicles, electric aircraft, etc.) there is a need to reduce weight and cost, increase efficiency, whilst maintaining security. One possibility is to increase current for the same device, and therefore how to draw away the heat. This is why conventional approximations need to be cross-checked with new tools. These new tools have to be quick and precise in order to run parametric and even optimisation analyses. Of course, thermal analysis is already available in the Flux suite for induction heating, induction hardening, forging, etc. Dedicated applications have been created to couple magnetic AC steady state to thermal transient analysis, for instance. What is new is easier and more effective coupling any type of magnetic application to thermal analysis. This article reviews what thermal analysis is, when the different tools were created, and looks at the latest advances in thermal analysis.

Explicit Dynamic Simulation of Tool Drop on the Outer Wing of the Swift020 Unmanned Aerial System using RADIOSS®

The successful launch of a new platform UAS is a comprehensive design engineering and manufacturing endeavor. The full lifecycle must consider maintenance and replacement components. As these requirements often require the use of tools (i.e. screw drivers, wrenches, pliers), the concern became apparent that as the flight surfaces are minimum gage, heavy tools dropped on the structure could cause irreparable damage. The objective of this project was to determine the specification for maximum maintenance tool weight such that, if dropped from a nominal height of 0.762 meters, would not cause permanent damage to any part of the Swift020 UAS. The Altair solution included a RADIOSS Explicit Dynamic Impact Simulation.

Developing Efficient Design Procedures for Wideband, Low-profile Antennas Using Altair FEKO Electromagnetic Simulation Technology

Low profile, concealed antennas are frequently desired for diverse applications across many military and commercial vehicle platforms. A vehicle underside can be considered a viable alternative place for concealment as it provides enough space to avoid extreme antenna miniaturization. A study conducted at the Antenna Research Group (ARG) at the University of Colorado evaluated the bottom side of the vehicle as an alternative to more conventional antenna placement positions for mounting high-frequency VHF antenna systems. Altair FEKO EM field simulation methods were applied to assess antenna performance.

Characterizing the Murchison Widefield Array Beam Pattern

A precursor to the SKA, the Murchison Widefield Array (MWA) radio telescope was constructed in the Murchison Radio-astronomy Observatory in Western Australia. In order to correctly calibrate and image the data collected by the radio telescope, it is imperative that the beam pattern is known accurately. In this study, a rigorous approach was applied where the full array geometry was simulated using FEKO with a goal to characterize the beam pattern of the MWA and demonstrate that this approach was more accurate.
