Hallo forum fellows,

I would like to familiarise myself with the BLDC Motor Drive and its control that is why I want to run the first example MotorTest01.asc "Brushless DC Motor Model Test with Trapezoidal PWM Drive". In spite of following the installation tips that are given in the Word Document "BLDC 3-Phase Motor.doc", I receive the error message " Could not open library file "C:\Program Files\LTC\SwCADIII\lib\cmp\standard.dio" " and I cannot find a way to solve this problem.
I have tried the following:
Supposing that the encrypted BLDCSupport.lib has the needed information e.g. about LIMIT,ABS,GAIN, INT, SUM2, SUM3 usw, then in BLDC.lib, I have written the complete path for BLDCSupport.lib,
* --------------------------------------------------------------------------------- *
.lib C:\Program Files (x86)\LTC\LTspiceIV\lib\sub\BLDCSupport.LIB
.lib SK_Friction.MOD
* --------------------------------------------------------------------------------- *
but it gave back the same message as above.

Could you propose a solution?

Thanks a lot in advance!!!

Many years ago, I had this problem. I created a folder
"C:\Program Files\LTC\SwCADIII\lib\cmp\ "
and copied my standard.dio file into it.
It all worked!
