Ok, I understood that voltage, much higher than rated for motor is not a good idea (unless in my case).
I tested IRAM board with 42 Volts. And motor behaves almost the same. There are positions where torque appears to be very low. Maybe there is something to do with how high and low transistors of different phases are switched? Now all of them switch on and off every switching period (let's say at frequency of 12kHz). Maybe I need to give some scope shots to make it more clear? Or should I compare it to 7i39 switching waveforms? Or maybe add current sensors and measure currents? ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
