Running a 3 phase band saw on single phase using capacitors

hertzal123

As above,I am hoping to run a 1.1kw machine using 120uf start and 60uf run capacitors as suggested

by a motor text book.To work,the motor windings will be changed to delta for the reduced voltage.

I understand the output power will be reduced by a third.Wondered if anyone has successfully used

this method?Thanks for any replies.

    Yes it does work, to an extent, but not as well as on real 3 phase power.  

    The more modern approach is to use a 3 phase variable speed drive of a type that will accept single phase input. Or to replace the drive motor with one intended for single phase supply.
