Model No. 13: This project is designed to provide low voltage start to induction motors. This is achieved by using star to delta conversion. This project uses a system to start a 3 phase motor at 440 volt AC mains supply 50 Hz with a set of 12 volt DC relays in star mode first and then to delta mode by an electronically adjustable timer. <br />Get more information about this project by visiting the page http://www.edgefxkits.com/automatic-star-delta-starter-using-relays-and-adjustable-electronic-timer-for-induction-motor
