Here's the scoop, I installed a 2hp rated vfd on a 2hp 240v 3ph motor that turns a ventury mixer. Without the drive belt, the motor draws 3.4a, 3.2a, and 3.4a. With the drive belt hooked up to the drum the motor fluctuates between 3.8a and 9.9 a....the result is kicking out my vfd. I hooked up a 3hp rated vfd and same results. I think I have a bind on my load side in either my motor under load or in the mixer drum. Am I correct in thinking this? I was told that a motor should only pull 30% of it's FLA with no load on it....if that's true, my motor is already pulling more than 50% with no load in it which backs up my hope in thinking that my motor is junk or I have a bind somewhere. Any more thoughts with this would be great! Motor is almost 50 years old to boot.
