Thread: Is this motor faulty?
If you can use a 4kw VFD then you have a 3~ mains. A normal 1~VFD have a maximum of 2,2kW.
Thats the maximum, what your 13Amp power socket is capable. The VFD can have more power then the motor, but should be in a similiar power range, 1,5 to 2 * the Motor is ok but not 5 times.
So, wired to Delta. 30uF cap, doesnt spin up, just turns slowly.
Connect a 300uF cap, instant spin up. Takes full load, can block the vacuum pipe with my hand, it just keeps going.
The only thing was that motor got hot very quickly. I didnt have the cowl structure on it so that meant no real cooling. It got hot very quickly however.
