Generating meshes and applying boundary conditions are optimized and conducted automatically to obtain the most accurate results in a short time. EMWorks has been tremendously helpful in my journey to design my brushless motor prototype. MotorWizard was the main tool that I used in the design process. It felt intuitive and relatively easy to navigate.
Once the stator is designed, it is very easy to create a 3D model. The motor has been tested and the results are accurate. It works just as expected.
I would strongly recommend MotorWizard solution to my colleagues and professors! Different motor designs can be generated by customizing the default templates. Permanent Magnets Brushless DC is supported with many types and shapes of rotor and stator parts. The topology editor turns the complex machine design into an easy and quick process with the auto-correction feature that computes adequate dimensions based on the selected configuration.
The initial performance prediction is a crucial step in motor design tests; thus, based on wisely defined approaches, instantaneous calculations of the design characteristics can be processed in few clicks.
By entering the input data, multiple steady- state results can be viewed and analyzed such as: Torque waveform, Air gap flux density, Back EMF, winding flux linkage, phase inductance, Co-energy, Core losses, etc. Electromagnetic machine behavior can also be accurately predicted through the Finite element-based analysis FEA where different test-oriented results can be obtained.
MotorWizard offers a user-friendly interface that makes the management of the created designs intuitive and time saving. Step by step, a heuristic workflow offers a concise period of mastering all the available tools and their features. Multiple analysis can be carried out in a short time and a restoration of previous design specifications is always permitted which makes the optimization of the design quicker and more efficient. Having defined major winding and power supply properties, you can readily obtain a variety of machine performance characteristics, including:.
MotorWizard uses the maximum torque per ampere MTPA approach to estimate the performance of the machine at different speeds. MotorWizard provides two types of analyses. Most results are based on pure finite element analysis. However, MotorWizard utilizes semi-analytical analysis to provide performance analysis results such as efficiency map and torque speed curve. The semi-analytical method uses both FEA and analytical methods. The analytical method uses the famous dq model of the machine. 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.
I was very impressed with one click I was able to obtain TDR results of my RF model which really gives me everything I am looking for, especially when other software like HFSS makes it such a pain to get similar results. 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 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.

The motor has been tested and the results are accurate. It works just as expected. I would strongly recommend MotorWizard solution to my colleagues and professors! 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. 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. The AC Magnetic module can help study a large number of devices and address numerous magnetic and eddy current effects. This technology is typically used in pipe inspection for the oil and gas industries. The Transient Magnetic module can help study a large number of devices and address numerous magnetic, eddy current, and transient effects.

Of course, you can always unlock the study if you need to make changes. You simply clone the original study, i. A cloned study inherits all features of the original study, i. There are two major sub-domains in electromagnetics: low-frequency and high-frequency domains. Both domains are governed by Maxwell's equations. The low-frequency domain includes the major part of the electromagnetic devices such as bushing, insulators, circuit breakers, power generators, transformers, electric motors, capacitors, magnetic levitation devices, synchronous machines, DC machines, permanent magnet motors, actuators, solenoids, etc.
Strictly speaking, any application in which displacement currents are negligible can be classified as low-frequency. The absence of the displacement currents de-couples the electric and magnetic fields and the situation becomes static. Typically, frequencies from DC to a few hundred MHz are considered low! The high-frequency domain includes the study of electromagnetic waves and the propagation of energy through matter. It may be sometimes difficult to distinguish between high-frequency and low-frequency.
Nevertheless, we can generally say that electromagnetic fields in which the displacement currents cannot be neglected belong to the high-frequency domain. Electrical machines and drives. Actuators, solenoids, and electromechanical. Electronic design automation and electronics.
