How to start the old inverter board without external sensors
Posted: Wed Jul 23, 2025 3:41 am
Hello,
I found this project and I think it would help me to build a VFD for a three-phase motor.
I don't need sensors - I use it for a fan.
Can someone help me start the inverter without the current sensors?
I would just like to be able to change the motor speed from a potentiometer.
