I don't know, but shouldn't matter I think. Both motors have same configuration, not selectable between delta or star (ie, not dual voltage type). Note that in this demo they are running from 240V mains, although the motors are rated for 415V. This is just to demonstrate a way to get 3 ph from 1 phase.
A 3ph motor will run from 1ph power, even at a lower voltage, if given a spin to start it. Use any 2 of the 3 terminals on the motor. When this motor is spinning, it generates electricity, and this shows up on the 3rd unused terminal. There's a second, similar 3ph motor, connected by all 3 terminals, to all 3 terminals of the first one via a reversing switch. After the first motor is started, the second motor can get 3ph power from the terminals on the first one. It doesn't need a helping spin.
