EC motor with modbus, inject DC
aeg:
Is it possible to destructively remove the IGBT and then power the motor normally?
MartinFO:
I have removed the large capacitor, within the yellow circle on the image and applied min. 70V DC (9V batteries in series). The status led starts flashing, though not as bright is under normal operation. The fan has 24V and 10V output, but I do not get any reading on the 24V and the 10V fluctuates (with the led) between 3V and 5V. The 5V increase with the voltage applied to the capacitor. At 170V I got smoke, but still not 10V at the output. I have more, so not a huge problem.
