Hi all, I’m trying to alter the Odrive to work from an ATEX verified power supply. This means that the current will be very much limited. I want to implement this by connecting this power supply to only the inverter. The rest of the ODrive will still be powered from a ‘regular’ power supply. I increased the resistance of the shunt resistors to increase accuracy. Does anyone see any problems in altering the ODrive in such a way. I would imagine that the voltage will drop quite a bit, especially at startup, will this be a problem?
The motor powered can be a very small motor. Is there anyone who can say anything about whether a BLDC motor will even start spinning from such a limited supply, since the inrush current will also be very much limited?
I added a schematic to give a bit more clarification about the modifications made.
