Crazy computer idea

Monday, June 21st, 2010

I’ve gone and purchased a small embedded computer to read the motor temperature and enable/disable the fan for the motor (www.parallax.com).  Nice stuff, very easy to work with.

However, since I now have this computing capability, why not use it to set the power settings for the controller as well?  The idea is that when the motor is cold, allow more power to flow into the motor, and when it is warm, turn down the power.  Azure Dynamics has 3 power settings available (max, norm, economy), and that is selectable by resistance into a line into the controller.

Hmmm.  This is gonna be fun.  🙂

Airscoops and Power Settings – FTW

After getting email from Azure and some really nice folks on the 914 conversion list, I have set the power limit for the motor to 30kw.  I’ve also installed some custom-made airscoops.

Net result:  no overtemp on the drive home.  Yay!  We’ll see how this works out for the summertime, but this means I can drive home now without a long stop somewhere.  (FTW == For The Win, if you aren’t into the geek slang).

Here’s a picture of the custom airscoop:
