Variable Frequency Drive

Thank You Bruce. I will let all know what I find

      Is your 5 Hp motor three-phase?  The only VFD's that pop up on a Google search for 5 Hp seem to be three-phase and $500 - $600 - $700.  ISTM that a VFD to start a motor is like gold plating a Pinto's wheels so they won't rust as it sits behind your barn with no engine in it.  Please do let us know what you find/how you fix this.

That right thar is funny an I don't care who it offends! BTW I wouldn't waste the time plating the wheels, however it wouldn't be a bad idea for the fire extinguisher so it was easier to spot!

   Not trying to be a smart aleck, just don't understand the details of making this work without spending hundreds of $$$ for a system that "ought to work" based on the numbers.  KISS ...

I agree with the above.  There is either a problem with the 5hp motor or the genset (maybe both).  The underlying problem is what needs to be fixed.  The problem needs to be fixed as it can only get worse.

Followup, I had the motor checked out and all that was found was the start switch need cleaned. The generator checked out OK. It still boiled down to the inrush needed for the higher torque motors and generators do not supply this inrush. The fix was to use a variable frequency drive to lower the amps required or use a smaller motor. I needed a motor for a planner I have so I got a 3 HP motor for about the same dollars as a VF drive. The amp draw on the 5 HP was 21 and on the 3 HP is 13. Problem solved all works well.

Thank You Wayne

    Good news - glad you got it worked out.
