What is the difference between normal linear motor simulation and a tubular linear motor simulation in 2-D? Although a normal linear motor and a tubular linear motor are obviously different but in 2-D simulation of both motors, what will we have to do different from normal linear motor simulation?
Does anyone have a link to Ansys Maxwell tubular linear machine simulation tutorial? I tried i could not find any.
Hello,
I would that what differs is the orientation of coils and magnets, even though geometrically they would look the same in 2-D.
I don't have anything done in Maxwell on linear motors, i just recently switched from another software... but you can look at the solenoid tutorial they offer (\Maxwell2D\Getting_Started\solenoid.aedt ) all the concept explained there are identical to those you'll need to apply to a tubular linear machine.
The process to you is quite transparent: once you select the Geometry Mode ("Cylindrical about Z", rather than "Cartesian XY") the model building phase is quite similar.
The main difference between "normal" and tubular linear machines is that in the former the field develops in a cartesian (X-Y-Z) plane, while in the latter the fields develop in a cylindrical (R-theta-Z) plane. The equations to solve them are different, even though you don't see any difference in the 2D geometry of the two models.
Another difference is evident if you think about it in 3D: in a planar machine the stator teeth will have a constant cross section as you move from the airgap to the stator yoke, hence their magnetic loading (the B field) will be roughly constant; in a tubular machine, instead, moving from the airgap to the yoke implies that your radius is changing, hence the tooth cross section and its flux density will change as you move from the smaller to the bigger radius.
