      Very nice work Peter, the servo motor runs very smooth. Is there any need to change the 20khz pwm, some of the VFD's can be adjusted but I thought it might have been to reduce any noise in the motor or something to do with toque, I will have to read the Manuel when I can find it.
  Another thought, I have seen electric car inverters around for sale, I don't have a clue if the control circuit and igbt modules are moulded together, there might be a possibility of driving one of those units, might not need a transformer, just high voltage solar input.
  The new Mega is much smaller than I expected, I'm going to have to me 1 of those to play with.         |
