During the initial startup, the motor is connected in star mode to reduce the initial inrush of current. Once the motor achieves the required speed, it switches to the delta mode, after which the motor can be loaded. ADLS makes use of the fact that whenever the load on the motor is less (<40%), it switches the motor to star mode, and as soon as the load increases (>40%), it switches the motor to delta mode. When the motor operates in the star mode its current consumption drops by 1/3, thereby saving energy. The saving is near about 10-40% depending on the motor load and the load changes. The more the in loaded time, the more are the savings. Certain industrial applications have observed more than 50% of the savings.
