As the picture showed, when I assigned a current excitation on the coil plane( pink one in image), Ansoft Maxwell alert ”current1 can not assigned on the entity of type face". This is incredible as I take the process completely based on the book!
I'm a starter in permanent magnet motor design, and learn to use the Ansoft Maxwell just yesterday! Hope you guys could give me hand, if there have some proplems in my process of designing and software using, Thank you！
Hi Guys,
I am modelling a simple Magnetic field in ANSOFT Maxwell 15.0. My geometry is a linear array of ring magnets (NdFe30) and spacers (iron) (OD-25mm, ID-13mm). they are arranged in a co-axial fashion and in alternating order (spacer-magnet-spacer-magnet-spacer ect.) and the magnets are...
Hello, is there a way to directly use a rectangular wave as input current without using an external circuit in ansoft maxwell? The instructions from ansoft that model a toyota motor just put the sine wave function directly into the winding's current settings, can I put a rectangular wave instead...
Hello people, I am trying to model a motor in maxwell that has an array of magnets in it , the thing is that I get the non zero forces for the magnets even when there are no excitations if I choose virtual forces , I am selecting the whole array of magnets so the computation should be for the...
Hi,
I'm trying to simulate a fault current limiter at ansoft maxwell 14 and i have a problem when i put the stranded option on winding, the current that appears is always positive, with the axis above zero. Anyone can answer me what's happening and how can i fix this?
Some date:

Hello everybody,I am busy with a magnetic transient 3D model and quite new in the use of Maxwell.
I am simulating a 6 pulse rectifier in double star connection (connection number 5 as per IEC 146-1-1). Each of the 6 arms of rectifier foresee 8 paralleled diodes.
I am interested to see the...
hi everyone.
I need to take a high quality picture of my design and its graphically results in maxwell but i couldn't find a proper solution.
I would be really grateful if somebody help me.
So I'm trying to run some 3D transient simulations based on magnetic field focusing/shielding, but I'm not getting the expected results. Does anyone know if Ansoft Maxwell 14.0 will solve for the magnetic fields created due to the eddy currents? It doesn't appear to.
Hello everybody i am trying to simulate some high air gap transformer. While Magnetostatic solution works fine , transient seems not to.
Actually i connect the first winding to a 90KHz voltage source and then in series with a capacitor.
The second winding in series with a Capacitor and a...
Hello everyone! I have a thesis about electromagnetic retarders. I need to do torque analysis for retarder; but I don't know how to do it on Maxwell 3D. I've tried Eddy Current solition; but analysis results didn't comply to electromagnetic retarder's torque charasteristic. Could anyone help me...
I am learning to use software to do some simple simulation. It seems that the Maxwell 2D/3D-parameters-assign-matrix option disappears sometimes. Under the menu of Mawell 2D-Parameters-Assign, only Force and Torque can be seen. In what cases the Matrix option is visible? What should I do if I...
For shaping an interior PMSM rotor from top figure to as in bottom fig, I made an equation based curve, united with another curve , made a surface using coverline and united that shape with my rotor.
When validated it showed band and rotor intersecting and I adjusted the band - DiaGap. Then...
Hi
I'm having an issue ANSOFT MAXWELL :
Assigning a permanent magnetic material to a body (for ex NDFE35) provides me a means of setting the magnetization direction (through x,y,z unit vectors ) inside the material settings
so if i have multiple PM bodies rotated :-
1- do i need to create a...
Hello,
I have to compare the real solution of the electric field radiated by a sphere, having 10 cm radius, charged with 1e-012 C (perfect conductor), something like E=f(x) where x is distance from the sphere, from 0m (surface of the sphere) to 1m, with numerical solution. I tried Ansoft...
Hi All,
I'm starting using ANSOFT MAXWELL and stuck in simulating a Transient 3D solver
i'm simulating a simple permanent magnet setup (attached an image) to examine fields/forces/motion
M1 is rotating around Z-Axis while M2 is fixed out of the motion setup
I'm seeking some guidance to get...
Hello!
I am a student of electrical engineering. I got assigned to a project where I need to simulate a coil in Maxwell 15 and a ball which floats in the magnetic field of the coil. This is for an experiment for demonstrating magnetsim, so my task is to find out what dimensions the coil needs...
Hello,
I want to simulate a coil of a transformer in Maxwell (3D), but my problem is: the coil design is not a closed path. Imagine that you draw a ring and then you cut part of it. You get something like a "letter C". In these two terminals I`m going to put an excitation (100A, for...
I am designing an energy harvester consisting of a magnetic spring.
The figure is given in the attachment.
I have done the magnetostatic analysis (using Ansoft Maxwell 2D). But, now I am facing problem with -
Force vs displacement curve of the moving magnet
To calculate the output power...
Hi experts,
I wonder anyone of you have an idea on whether we can include a discrete component (specifically a capacitor) into an "Ansoft Maxwell 3D" eddy current design. Little more description: I do have a specific eddy current design with a coils. I need to add a series capacitor and...
I am designing a 2D model of a three-phase core-type transformer in ANSOFT MAXWELL 14.0. While doing so I have encountered a strange problem.
Start of the problem:-
While designing the transformer, I wanted to incorporate core losses. So, I did the following steps:-
Excitations -> Set...
Hello! I am having an issue with getting any graphs on inductance or induced voltage.
In the attached circuit:
What I have is a 28Vac source w/ 400hz and 2 coils (R=18.6ohm each) that are connected with a common.
In the model:
I have a core in the center that will be able to move up...
Hello
I am new with Maxwell. I made a motor drawing in solidworks and imported it in maxwell.
I found some tutorials, and searched on the internet but could not find answer to my problem.
So when i try to assign Excitation Current to an coil i get the message
Excitation 'Current1' : Cannot...
Hi,
I had modeled a simple transformer with Maxwell 3D (one closed iron and 2 coils), all seems all right except the output voltage, I have only 300 mV and I must have 12V ! I join the files, if someone can help me ? A strange thing is the StrandedLoss which up to 350 kW ! where's come from...
Hi,
I would like to measure the power give from a source to a transformer and measure the power consume by a RL component. I see only voltmeter and amperemeter in circuit editor, it's not possible de put wattmeter ? Or maybe there's another solution for find the power ?
Thanks in advance ;)
Hi,
I'm tring to explore magnetic field of the contact system, but when I set the current on a face, i have the next error:
"An external terminal must border the edge of the problem region and coincides with the surface of a 3D object"
I solve this problem when I set region overlap with this...
hi all,
i need some help about modeling a coil on maxwell 3D(transient analysys.).my problem is defining coil terminals.i have 6 coils(star connected) and 3 current source(star connected).i attached my work.coils are solenoid style winded.(ring style winding) and each coil has 130 turn.i...
I need the inductance of a simple ferrite core wire-wound inductor.
It's not clear how to get than in 2D Maxwell SV.
The core is one material (ferrite), the windings are another (Copper).
If you group them, the group must be of a single material, so no good.
If you don't group them...
Hello, can anyone assist me in building a geometric model of an RG58 coax cable with Ansoft Maxwell SV using the appropriate solver to solve for the series impedance of the cable per unit lenght. The Ansoft Help files available do not cover this.
