Running a 3 phase band saw on single phase using capacitors

hertzal123 over 1 year ago

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.

Regards,

And there lies the problem! Did you really think that the manufacturer of the band saw overspec'd the power of the motor by 33%? Do you think that it will run satisfactorily on a bit over half of its previous mechanical power?
