BL Motor Evaluation program

[GriffinRU]

Writing a program to simplify BL motor selection. In general I have an idea what to plot and which parameters to display, but would like to hear others as well. First iteration will be focused around 540 Feigao motor but later database can be extended including custom motors (user will specify motor parameters).


There are plans to import Lehner .xls files direct from web or just add them to database, similar can be applied to Hacker and Kontronik motors, need to check for Neumotors data.

Attached printscreen shows 540 7XL perfomance, rated and full (theory)

Very nice! What are you using to get the measured numbers?

Using DC motor model and NI LabVIEW software for programming.

Motor parameters: Kv; I no load; I max; R and L

Later motor dimensions to calculate rated power and no load current plus nominal voltage.

Heat dissapation and heat sink size also on the way. Plus ESC switching freq and connectors resistance...

Sounds like a good thing to have. Now, someone needs to make a BL dyno to validate the calculated results. :)

This one will help to understand how it works plus rated powers and alot more, dyno will prove only one particular setup/given motor.

P.S. I need to make program installer smaller, for now it is 70Mb, way to big for publishing and downloading... :( (Program itself 2.41Mb) Windows business...

Awesome Artur!

this will be a big thing IMO!!

You can use some kind of a 'wise installer' you can start this software, install things, change things in the register etc. and after that, it creates an executable file of all the things changed, this file is the install file.

Again, great work Artur!!

Thank You, Rene, I am working on it...

If not today tomorrow I will put alfa version :)

Download, requires NI 8.2 Run-time Engine

[BrianG]

Argg! You have to register to get the runtime. And then, it's a 94MB download (and the server is pushing it at me at only 365kB/s)! I really hope it's worth it! :p

Great Artur!!!

I'll download it when i get home! great, looking forward to have a closer look..

It's not in Russian!? my russian would be less good than you English.. :p

Wow, a 90MB download for a 2.4MB program, yikes. Looks very cool... I haven't got it yet.

[sjcrss]

I just downloaded it.....very cool...great job

[neweuser]

Another very useful tool! Great Job! The more info the better!

[GriffinRU]

I am sorry for size...

But here comes an update, no more NI and 2 versions one with full-blown installer and another just files required to run (keep them in the same folder).

Download Full installer (8.93MB)

Download Just program (5.58MB)

Very cool...graphs and charts...submenus for different displays ....thanks

Seems like you have the entire Feigao line covered but is there anyway we can add motor data ??

thanks again

This is great. Is temperature in faranheit or celcius?

You should allow for higher voltages too. Up to 50V should be plenty.
