In another step forward in the computer modeling world, MDL has put together a tutorial for their motor modeling package that can model the Nissan LEAF motor for you. Read all about it here, on MDL Torque: Using Motor CAD to Model Nissan Leaf
From the story:
MDL have developed a tutorial to demonstrate the use of Motor-CAD and Motor-LAB to model the electromagnetic and thermal performance of the Nissan LEAF electric traction motor. ...
MDL software is used to predict the torque-speed characteristics, efficiency map and transient thermal analysis with the US06 drive cycle. Validation of the models is performed using measured efficiency maps and thermal transient data available in the publications on the internet.
The full analysis can be performed in just a few minutes as both Motor-CAD and Motor-LAB are optimized to give fast and accurate calculations.
This comes from Motor Design, Ltd, a company that develops "... advanced software design tools for electrical machines and motor design consulting. ... to provide software and support to electric machine designers." Why is this cool, you may ask, O ye of the ilk of non-engineers? We thought you'd never ask.
Basically, computer modeling of almost any kind allows you to mess with a design and see probable results without having to actually, well, do it. For example, let's say you think that adding some cooling fins to the extreme frunobulator of the composite extrafabuliculator will give you an efficiency boost on your LEAF, as well as keeping your whites white and your brights bright. The old school way? Take your motor and run some baseline testing. Do more baseline testing to verify your baselines. If you're really cool, you do it on, oh, maybe a dozen motors to verify the data.
Now, add those fins to the extreme frunobulator of the composite extrafabuliculator. Good luck finding the extra modularity sensor arrays that will fit around that new frunobulator. Got that done? How long did it take, about 6 months? OK, do it to six more motors and get back to us. Now, run the tests and see what the data says.
Or, run a modeling program. The finer the resolution of modeling, that is to say, the tinier the details are in a system you can model, the more profound any projections can be. Rather than glossing over a small detail, if you can model it accurately, you can predict more accurately when you model the bigger system. ...so this is a finer-resolution modeling system for motors.
Motor-CAD and Motor-LAB, from Motor Design Ltd, has been around for a while, however. This announcement is simply a tutorial they've released for it. So maybe even we could use it. Who's your (nerdy) Daddy?
