Static phase converters don't produce a three-phase sine wave.
They are just a couple capacitors and an SCR. I have heard they
just get the motor going, and the waveform is more like single
phase than anything. A 3-phase motor will run on single phase if
you spin it up by hand and apply the elec. I think you will have
to go to a rotary converter or something that produces a true
3-phase, 50 Hz waveform. If you have access to a scope you can
test the phase converter output and probably convince yourself
that the problem is there.
