Hello, I've been reading this post: https://www.practicalmachinist.com/...ease-help-capacitor-sizing-7-5-hp-rpc-318947/
as well as some others about setting up a rotary phase converter.
I have a 3PH 50HP 4 Pole load that I need to run so I got a 3 Phase 100 HP motor.
The Idler motor;
100HP 75kw
220/440 volts
236/118 amps
The load motor;
50HP 37KW
220/440 volts
124/62 amps
There is a document that I am also following: https://www.practicalmachinist.com/FitchWConverter.pdf
Along with this youtube video: YouTube
In the above video and PM post both were using 7ish hp motors.
I am using 100HP which is a bit more.
Some articles that I've read says it takes 100-200 microfarads per hp and it's been said that this scales linearly. Is that true?
I understand that balancing a RPC uses different capacitors for start and run purpose.
I plan to run with 220V since that's the closest thing that I have access to. Can someone assist me with properly sizing start capacitors?
