Usually when talking about "single-phased" motor, it means
that two of three phases are connected. In these cases, the
motor will slow down, and the phase currents for the
remaining phases will be increased. I don't know how much. I
am also not sure if the overload device would cut-off the
motor from power supply. Unless problem is not noticed, the
motor will most likely burn. When the motor is opened, you
should be able to see that 2 of the 3 phase windings are
black, and one is good looking (if motor is Y-connected)
