Getting Started with Maxwell 3D (ANSOFT)

Ans 1...in stranded field eddy current losses of the coil are not counted while in solid these are take into count...
Ans 2..No it is necessary to assign matrix it will give warning like boundary condition and excitation and 2nd thing is that you can not import this file into another software without matrix.
Ans 3...of course eddy current

Hi.
I need to use sinosuidal voltage source, my voltage is u(t)=U*sin(wt) where U is peak voltage sqrt2*30 and w=2pi*1000hz. I need to get data of i(t). I have 3 coils in parallel. do i use voltage type on windings or external circuit?

I think both will work

regarding 2nd answer... i am talking about the case where i assign excitation on both ends of coil - one current goes in the coil, other goes out. i tried simulating with and without applying matrix,and it worked.

Hi all,

I have the problem that maxwell 2D simulates wrong forces regarding permanent magnets.
At first I have simualted a solenoid with a permanent magnet, we build a prototyp afterwards and all forces were just half as simulated.
Afterwards we simulated just a N50 Magnet on a Steelplate and maxwell 2D still gives twice the force as the reality.
Solution type is Magnetostatic and geometry mode is cylindrical about z.
Did anyone else also had this kind of problem in the past? Did i configure something wrong?
thanks in advance
Michi

I did not work in Maxwell 2d, but I worked in 3d. I know it happened to me that I get different results if I select region only and generate plot, or If I select region and objects. Maybe you should try to select different selection, if you understand what I want to say.

Im designing a 4 pole PM motor in Maxwell 16. As mentioned earlier in the post, the induced voltage from "generate quick report" is just the induced voltage due to the current. I need to find the terminal voltage and the back EMF. Any help/advice is highly appreciated.

Hi. I have magnetic bearing with 3 coils, and I need to calculate magnetic force. 1. What solution type should I use? 2. Where do I input data like mass of my rotor or gravity that's pulling him? Rotor can be in motion or stationary.

Thanks

Hi friends,
I am designing a 3D model of a one-phase core-type transformer in ANSOFT MAXWELL 16.0. I have a big problem in winding's excitation.

In my transformer:
N1=turns of High Voltage Winding = 88 turns (44 turns in 2 layers that every layer including 2 parallel tape),
N2=turns of Low Voltage Winding = 46 turns (46 turns in 1 layers that every layer including 4 parallel tape),

My questions are:

Q1: For External excitation, I do not know: what is "Number of parallel branches" in my design?

Q2: In assign excitation ----> coil terminal excitation, What is the "Number of conductors" in my design?

THANKS A LOT all.

Hi
I believe you have to set conductor in primery 176 and nubmber of parallel branches 2.
And in secondary number of branchea 4 abd 184 conductor

Or ignore parallel branches and set 88, 1 , 46,1 respectively and just consider the true resistance for parallel coils .
Dear all . If I can help you on ansys maxwell specially on rotational machines please contact me on whatsapp or telwgram with +989379371182

Thanks a lot.
For "consider the true resistance for parallel coils", If I select the material of winding (such as: copper) in maxwell, It is enough?
or I should be add a resistor in external circuit?

Hello every buddy.
I've modeled a linear induction motor in Maxwell3D. Selecting the "Translation Motion Type" in "Motion Setup", I face the following set of errors:
Maxwell3DDesign1 (Transient)
[error] Invalid moving objects. All moving objects inside band must form single connected region. (2:36:21 PM Nov 14, 2016)
[error] Motion setup (geometry) is not valid. (2:36:21 PM Nov 14, 2016)

These errors occur only in translation motion.
I'll be grateful if anyone helps me.

Hi. I also faced the same problem with you. Can i know did you solved your problem because i am new in translation motion type. If you already solved the problem, may I know what are the solutions that you made. I'm so grateful if you can help me because i really don't have any idea on how to solve it. Thank you in advance

This means, that moving/rotating element must be contained in single element i.e. rotor must be contained in a circle slightly larger than rotor outer diameter (circle for 2D simulation, obviously). Example: in case of a induction motor when rotor has outer diameter of 100 mm while stator has inner diameter of 102 mm you need to draw a circle (in case of 2D sim.) of 101 mm (centered with rotor).
