One thing I forgot to mention: Motor reaches its max RPM approximately at bldc value = 0.4...0.5 and then remains the same, motor just gets louder as value is increased to 0.95 (or -0.95 respectively). I tried to play with 3pwmgen.frequency parameter - tried 20 kHz and 45 kHz, 45 kHz provided higher RPM for bldc value = -0.95, it remained approximately the same for +0.95. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
