Reversing induction motor

G

Gazzman

I want to reverse an induction motor (industrial fan, single phase). I've located a site on the net that advises substituting the start capacitor with a choke, specifically the secondary winding of a low voltage transformer. In that case 24v transformer with a 120v supply. I've tried it and the concept works !!

My question is how to calculate the correct size choke (transformer) for a 240v supply. Anybody know of a formula? Thanks if you can help me out.
