SIEG X2 MINI MILL BELT DRIVE CONVERSION: My version with 220V 3 phase motor and VFD

Another project is finally finished: SIEG X2 aka MINI MILL BELT DRIVE CONVERSION.

The original SIEG X2 DC motor prematurely left me with a piece of junk, cause to carbon brushes spikes. I tried to change mosfet, but after another set, i decided to convert this machine to belt drive.

The new version uses a 750W motor (1HP) with a Mitsubishi VFD.
