Hello, it is generally not possible run a 3 phase motor with single phase (2 wires) under a load... it IS possible to keep it spinning, under no load, for a while that way, the term is called 'single phasing'... and refers to a negative condition in which the motor can carry no load and over heats or burns out.
There are some exceptions however
It can also be done by fitting 'run capacitors' between the two legs with power supplied to them and the third leg of the motor that you are not supplying with power (3 phase).
