EMS solver is fully compatible with Solidworks and it allowed us a very short learning curve. With basic knowledge of Solidworks we have mastered EMS in less than two working days.
The use of EMS definitely added value to the course and enhanced students' learning experience. EMS is quite useful program for finding electric and magnetic fields in unorthodoxly shaped assemblies. It has been especially helpful for me when I was trying to design circuits with high voltage and current applications, which are potentially lethal for students. EMS comes with a set of tutorials that guide users through the model setup and demonstrate a large variety of applications.
Overall, a very professional electromagnetic simulation software. The EMS magnetostatics module has been amazing for designing permanent magnet configurations to optimize magnetic field shape.
The interface with SolidWorks is really intuitive and I was able to start using it quickly. Even better, the customer service and tech support have been wonderful! I highly recommend this software. I started using EMS because I was looking for a software that could compute accurate 3D magnetic field results, and at the same time provide all the associated variables, such as inductance, force, losses etc.
Not only EMS perfectly fulfilled my simulation demands, but I also benefited from the great tech. I used EMS software for the induction heating analysis of a gear.
The transient magnetic analysis helped me obtain good simulation results which corroborate what is mentioned in the literature. The software has a user-friendly interface. Moreover, The EMS license comes with a set of pre-defined tutorials and Demo Viewer examples to guide the users and help them get familiar with the software.
I had a good experience with EMS. It is a powerful simulation tool that I would recommend to anyone who is doing projects on induction heating. With this tool, we can model many types of coil designs, such as using thin magnet wire, and water cooling it, or instead going with hollow-core type of wiring with finite diameters and realistic spiraling modeled in SW and running cool water through that. We can then see our magnetic field profiles all around the coils, and of course in the center of our Helmholtz configuration, where we would like to ensure very flat magnetic fields.
In a complex environment such as a cold-atom experiment, I want to ensure that the vacuum chamber geometry itself would not impede our ability to ramp up and down the current on the magnetic coils, due to eddy currents. By tuning the materials, and in real-time designing components the way they would be engineered, we will be able to fine-tune our apparatus to our needs and constraints.
In the future, we will continue to evaluate the eddy currents present in our system as we try different parameters for our magnetic field control see image. One great aspect to continue expanding on would be the video tutorials highlighting the many ways to get students started on using EMWorks for their applications. The image shows a cut-away view from our new vacuum chamber. We want to verify the compatibility of a new magnetic coil system with the chamber.
EMS can be used as a transformer design software. EMS can be used to virtually study critical transformer design parameters, including:. A transformer shall not store any energy but rather transfer instantaneously from input to output.
Unfortunately, in real life transformers do store some undesired energy. EMS computes the leakage inductance which represents the stored energy between windings regions occupied by non-magnetic media. Similarly, EMS calculates the mutual inductance which indicates the amount of undesired stored energy in the magnetic core and small air gaps.
To calculate the said temperature rise, EMS takes into consideration all transformer losses including, eddy loss, hysteresis loss, core loss, winding loss, and heat loss as well as the surrounding liquid temperature and convection properties.
EMS calculates the magnetic flux density and saturation levels in the core which can help in selecting the proper core material, shape, and size for any frequency and desired power output.
Open and short circuit tests of a transformer are critical but costly and time consuming. EMS enables the designer to virtually run these tests accurately and efficiently.
EMS calculates the dielectric breakdown which is instrumental in selecting the proper bushings, surge arrestors and other insulating infrastructure. This type of calculation helps the designer meet the various insulation coordination standards. EMS calculates the magnetic force acting both on the windings and the core material as well as the stress and structural displacement due to these forces. This type of calculations is helpful in guaranteeing the structural integrity of the transformer.
EMS can be used as a motor design software and can be used to virtually study critical electric motor design parameters, including:. Winding inductance and resistance play significant role in control and state estimation of electrical motors.
EMS can determine these parameter values for a desired set of frequency and current conditions. EMS is full 3D modeling platform.
This enables simulation of some important topologies and effects which are otherwise impossible to analyze: -Skewing of slots or rotor poles is a common technique for cogging force reduction. Its results can be estimated only if interaction between stator and rotor is captured in all 3 dimensions.
Torque results for different rotor RPMs and winding currents determine the optimal operating conditions. Furthermore, EMS helps minimize the cogging torque by comparing its magnitude for different air gap lengths or fractional slot pitches.
Successful machine design depends on accurate representation of nonlinear phenomenon in the core material such as flux saturation, eddy current and hysteresis losses. EMS comes with a library of predefined solid and laminated core materials. Designer can easily compare different materials in terms of the saturation, core losses and overall efficiency.
Core and winding loss results can be coupled with EMS's thermal solver and determine temperature rise and cooling requirements. Machine radius, length and number of poles will greatly determine its torque and power rating. However, finer geometrical features of the magnetic circuit have profound effect on the machine performance.
For example, shape of squirrel cage bars in an Induction motor will affect how torque changes with the rotor slip. All these parameters can be readily varied inside EMS to evaluate their effect on the performance of the motor.
That is, it accurately calculates the resistance, the inductance, and the capacitance for any arbitrary 3D electric and electronics structure. These calculations take into consideration the proximity effect, the skin effect, the dielectric and ohmic loss, and the frequency dependence. These parasitic values are instrumental in modeling various electric and electronics devices and circuits, including:. RLC models for high-speed electronic devices such as ICs, PCBs, packages, and on-chip passive components are crucial in studying crosstalk and distortion, interconnect delays and ringing, and ground bounce.
RLC models are useful in simulating power electronic equipment such as bus bars, cables, inverters and converters commonly found in power distribution applications, and hybrid and electric vehicles. Electromagnetic fields and waves are widely used in the nondestructive testing technologies. EMS seamless integration in the three main CAD platforms empowers you to simulate the most intricate electrical machine, motor, generator, sensor, transformer, high voltage apparatus, high power machine, electrical switch, valve, actuator, PCB, levitation machine, loud speaker, permanent magnet machine, NDT equipment, inverter, converter, bus bar, inductor, bushings, or biomedical equipment.
You don't need to "reinvent the wheel", just acquire a CAD model from the mechanical drafting personnel and start your magnet or magnetic simulation instantly without any modification. Change it yourself "on the fly". EMS is a true multi-physics software and simulation package. It enables you to couple your magnet, magnetic, and electrical design to Thermal, Structural, and Motion analyses on the same model and mesh in a hassle-free integrated environment without any need to import, export any data.
This integrated multi-physics environment means: no cluttering, no jumping around, no mishmashing, no chaos, no confusion, and no mess. It also means: efficiency, accuracy, and productivity. Your design involves electro-thermal aspects? Easy and hands-free! Just check "Couple to thermal" steady-state or transient in the study properties. EMS automatically computes the joule, eddy, and core losses and feeds them into the thermal solver.
You may readily add non-electromagnetic heat loadings by applying volume heat, heat flux, or simply fixed temperature. Taking into account the environment conditions such as convection and radiation, EMS thermal steady-state or transient computes the temperature, temperature gradient, and heat flux and saves them to "Thermal Results" folder.
By the same token, the electro-mechanical coupling is also easy and hands-free. The "Couple to structural" option invokes the EMS structural solver, after transferring the local force distribution in relevant parts in addition to the mechanical loads and constraints, and then computes the displacements.
The stress and strain are deduced subsequently and added to the "Structural Results" folder as well. If the more general electro-thermo-mechanical coupling is desired, EMS transfers both the thermal and structural loads to the Thermal and Structural solvers. The Thermal solver, in turn, feeds the thermal loads to the Structural solver which computes the final displacements that reflect both the electromagnetic and the thermal loads while taking into account the magnetic, electrical, thermal, and structural environments.
Electrical machines and drives usually encompass moving parts and components. Generally speaking, the resulting motion is simply rotational such as motors or translational such as linear actuators.
Nevertheless, some applications such MagLev and Eddy current braking may provoke all the motion six degrees of freedom. In such case, only EMS can handle such intricate machines and equipment. That is it and that is all. Consequently, you can simply grab a CAD model from the depositories, make necessary changes, and start your finite element analysis instantly.
Electromechanical, electromagnetic, and power electronics devices can readily be studied using EMS. Electromagnetic behaviour could also be investigated with EMS. Electrostatic approximation rests on the assumption that the electric field is irrotational, i.
From Faraday's law, this assumption implies the absence or near-absence of time-varying magnetic fields, i. In other words, electrostatics does not require the absence of magnetic fields or electric currents. Rather, if magnetic fields or electric currents do exist, they must not change with time, or in the worst-case, they must change with time only very slowly.
In some problems, both electrostatics and magnetostatics may be required for accurate predictions, but the coupling between the two can still be ignored. Electric Conduction is, in essence, based on the electrostatic approximation. Unlike the Electrostatic analysis which deals with insulators and electric conductors, the Electric Conduction deals with only conducting media which can sustain a current flow. Magnetostatics is the study of static magnetic fields. In electrostatics, the charges are stationary, whereas here, the currents are steady or dc direct current.
As it turns out magnetostatics is a good approximation even when the currents are not static as long as the currents do not alternate rapidly. Furthermore, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null. AC, or alternating current, Magnetic, is the study of magnetic fields due to alternating, or time harmonic, currents. Similar to Magnetostatic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.
Transient Magnetic, is the study of magnetic fields due to time varying currents, typically caused by surges in currents. Similar to Magnetostatic and AC Magnetic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null. The Electrostatic module can help study a large number of devices and address numerous insulating and conducting phenomena.
This phenomenon is common in high voltage and high power applications. The Magnetostatic module can help study a large number of devices and address numerous magnetic and electromechanical phenomena. Magnetic saturation is a limitation occurring in ferromagnetic cores.
Initially, as current is increased the flux increases in proportion to it. At some point, however, further increases in current lead to progressively smaller increases in flux.
Eventually, the core can make no further contribution to flux growth and any increase thereafter is limited to that provided by air - perhaps three orders of magnitude smaller. The cogging torque of electrical motors is the torque due to the interaction between the permanent magnets and the stator slots of a Permanent Magnet PM machine.
Also termed as detent or 'no-current' torque, it is an undesirable component for the operation of such a motor. It is especially prominent at lower speeds, with the symptom of jerkiness. The Electric Conduction module can help study a large number of devices and address numerous conducting and joule effects. Rather, if magnetic fields or electric currents do exist, they must not change with time, or in the worst-case, they must change with time only very slowly.
In some problems, both electrostatics and magnetostatics may be required for accurate predictions, but the coupling between the two can still be ignored. The Electrostatic module can help you study many devices and address numerous insulating and conducting phenomena. Below is just a partial list:. The Electrostatic module is primarily used for computing electric potential and electric field due to charges and voltages in insulators and conductors.
It has many practical applications, including:. The Electrostatic module outputs the following results for each study:. Electric field and electrostatic simulation software. Google Play. Biden to send military medical teams to help hospitals.
