Why doesn't the well pump pump water when plugged in?

Good afternoon! Tell me what could be the reason. I connect a single-phase well pump to a 3-phase circuit (a new section, the house has not yet been built, there is only an input for 380 volts). 4 wires come to the shield, as usual, 3 phases and PEN (as I understand the most common scheme for suburban areas). I put one wire from the outlet on phase A, the second on PEN (or zero). I check the voltage in the socket - about 220 V. I plug the pump into the socket, it buzzes, but does not give water - that is, it does not pull, as I understand it. I pulled out the pump several times, checked the connection of the pipeline - everything is fine. Then he replaced the same one with a new pump - the situation does not change. I take a gasoline generator for 220 and connect through it - it works perfectly, everything pumps up at full power. Could there be a problem in a three-phase voltage network? I broke my head. Thanks in advance.
