Your video is great. Try to invest on a pen tab so that you can write properly on your screen.

The direct online (DOL) starter method of an induction motor is simple and economical. In this method, the starter is connected directly to supply voltage. By this method, small motors up to 5 kW rating are started to avoid the supply voltage fluctuation.
