how to calculate the capacitor to single phase induction motor (from 3 phase to single phase)?

 

Responding to Salatoo's Tue, Oct 12, 8:50pm query... are you asking:

"What size capacitor is required to operate a 3-phase motor on a
single-phase supply?"

you need a capacitor of 70µF/kW to convert a 3~ to 1~ motor but i don't have the precise formula.

attention the power of the motor decrease about ~20% and you have more thermal losses.
