Connecting an ELNOR motor through capacitors

Thanks for the reply in https://our.electricianexp.com/en/kak-podklyuchit-dvigatel-elnor-220-volt.html. Started with 10 microfarads + 12 + 10 + 20 and only then started. It works fine, but stops when the sewing machine is turned on. I tried with a star and a triangle. Help me to understand. ELNOR / 0.55KW. 240 / 415V. 2.3 / 1.3A / 2800ob / min. According to the calculations, 6-7 microfarads per 100 watts.
