Vfd motor starter wiring schematic
The humming problem is likely to be less with the starter vs switch, than it is with the wiring to the motor, or some problem inside the motor. Feb 18, 2018 · Mark I hope you know that
with out your help and guidance many here could not do a VFD install that is so carefully thought out. I have no machines to do this to at this time but in the future your work is a reference that I will use. Hi Nasir, You can try to use VFD or inverter to drive your submersible pump.The inverter input power supply is single phase 240V and it will convert to 3 phase output to your motor.But please consider your Inverter current (ampere) rating same rated or higher than motor FLA.Rule of thumb to sizing your inverter is –> FLA x 2 = VFD current rating. you can use the same basic circuit, get a 24v coil for your motor starter, and a small transformer to supply your 24v, unless you have 24v somewhere else.
