BL Motor Evaluation program

[BrianG]

That 8.93MB download is MUCH more manageable! Good job. :)

Would it be feasible to place the motor data in an external "ini" text file? That way, data can be added without requiring a program recompile. Judging by the data produced, there must be quite a lot of required parameters for each motor?

I also agree that the voltage should go a bit higher since there are some of the high wind motors listed.

I would say the temp is in degree C.

Temperature in C and related so far to copper losses only, later plan to add core losses but without proper info on core and windings would be difficult to do that.

Plan to add import and export feature for motor data as well as ability to create custom motor or edit existing. If ini file sound good for editing I will do that, but I was planning do that inside program. (smaller database)

I am working on adding nominal voltage calc for each motor turn and preset voltage automatically upon motor selection. Or voltage can be fixed (fixed battery type). By the way battery and ESC can be and should be covered as well. Right now total wires resistance to motor set at 0.025Ohm. Later I will add it as user selectable, based on FET's Rdon and Temp plus number of connections (deans, tamiya, anderson... soldered).

As for Alfa version it is possible to enter any voltage, double click on maximum value and replace it with new one.

Thank you all for feedback,
Artur

i can download the software, the full version.
but then when i install, the computer suddenly stops and says:
"cant find source object" or something like that.
what should i do?

Which OS are you running?

Under Program Files/Motor test folder you should see 4 files:
- BL_EVAL.exe
- BL_EVAL.ini
- lvapp.rsc
- lvrt.dll

If any files missing try to reinstall program, check for any anti-virus software and admin privileges as well.
You can uninstall program via add/remove programs or by setup program. If you run setup first time it will install product, run it second time it will uninstall.

Let me know how it goes.

Where I can find Maximum current draw for Neu Motors?

Next update will include:
- Lehner motors
- Neu Motors
- Feigao Motors

Hacker, Aveox, Novak, Tekin, Mamba are coming soon.

P.S. I created .xls template for motors if anyone would like to help that would speedup program development.

Check out www.neumotors.com and www.flydma.com. Both have useful info on the Neus.

Thank you,

Second link has the data I was looking for :)

Good job!

A suggestion: Could you put the links to download the apps in your sig. That way, we all know where to get the most current version without trying to dig back through the thread...

Ok, I will do that later.

Updated version 1.0.3 (7.5MB)

I just installed the updated version and get this error message,I deleted the previous versions folder prior to installing the new version if that helps.
thanks in advance

It loaded fine for me.

It looks like the new version uses an excel file to store motor data. Do you have Microsoft Excel installed?

[BrianG]

I like this new version! The addition of having motor data in an external file is nice! Great job.

OK, now for a couple of suggestions.

In the attached pic, there are two circled areas, "Note 1" and "Note 2".

Note 1: It looks like there is a little alignment issue where the column name over-writes the other column. Not a big deal, just wanted to point it out.

Note 2: The units are not shown. Most people know that torque is in oz-in, power is in watts, etc - but it may not be obvious to some. Maybe put the unit in parenthesis, or at the end of the output field? The units are displayed on the columns, so maybe that's good enough and I'm just being too picky. :)

Is it possible to add a pointer so that if you click somewhere on the x axis, it will display the values for the curves at that point? For example: Let's say I want to see exactly what power, current, and speed there is over a certain efficiency range. I would click somewhere on the efficiency curve and then some type of informational box would appear showing the values of the corresponding curves at that point on the x axis. Again, not a big deal - it would be just another neat feature.

Thanks again for this tool! It is looking very nice!

Well, I was using Excel to make it simple... but I will create another way to edit database. For now you can download attached file and unzip it to program folder.

I am using Excel only to import data, program only reads Excel upon first run (to create separate file) and when user clicks update via menu. This way you have more flexibility with data.
