This device can be wired to the motor you plan to run that requires single-phase power. The three phase supply current produces an electromagnetic field in the stator winding which leads to generate the torque in the rotor winding of three phase induction motor having magnetic field. It provides a unique feature which is a rotating field in order to rotate the motor without the need of a starter circuit. Since applying single phase power to a 3 phase motor will not start it rotating, a means to start the idler motor turning near rated speed is necessary.
