How to connect a three-phase asynchronous motor 380 to a single-phase 220 network?

Valery asks:

Hello. How to connect a 380v electric motor to a 220v network And how to choose a capacitor, according to what formula?

The answer to the question:

Hello! And what is in his boron? Just three wires out? Just on the nameplate, I do not see the data for inclusion by a triangle. In this case, you need to switch the windings. You can of course try to turn it on, but the power will be several times less. The connection scheme is standard for such cases, to one of the windings - phase, to the other zero, and to the third phase through the capacitor

The formula for calculating the capacitor for starting a three-phase asynchronous motor connected to a single-phase circuit according to the "Star" scheme is as follows:

Cp = 2800 × I / U; I = P / (√3 × U × η × cosφ)
