Capacitor Calculations

Best ask the pump manufacturer. It's not something you can calculate, and every motor is different.

Thanks for the quick reply.I will try and contact the pump manufacture.

I managed to fimd the following.

A rule of thumb has been developed over the years to help simplify

this process. To select the correct capacitance value, start with 30 to 50µF/kW and adjust the

value as required, while measuring motor performance.

I asked the same question about 6 months ago and the best I got was 25Mf / hp which roughly coincides with what you have found elsewhere.

Mf is incorrect. Capital M means Mega, or one million. I don't believe anyone has produced a capacitor anywhere near a Million Farads...

if you don't know how to use µ, then please write out micro-

Thanks

I will let you know when I get some results.
