Abstract:
A method for supplying power to an induction motor system having a first power generation means constituted by a first rotor and a first stator which surrounds said first rotor and on which a first stator winding is wound and a second power generation means constituted by a second rotor and a second stator which surrounds said second rotor and on which a second stator winding is wound, said first and second power generation means being connected to a common load, said method comprising the following sequential steps:a first step of supplying power to said first and second stator windings after both the windings are respectively connected in a star-form;a second step of supplying power to said first and second stator windings after a connection of said second stator winding is changed into a delta-form while a connection of said first stator winding remains as the star-form; anda third step of supplying power to said first and second stator windings after the connection of said first stator winding is changed into a delta-form while the connection of said second stator winding remains as the delta-form.
