What is the difference between dol and star delta starters? Both devices are used to start induction motors however, where partial voltage is applied to each winding of a star delta starter, a DOL has 100% voltage applied. This also applies to the current, a star delta uses one-third of the starting current that a DOL does. Direct on line starters are the most common and simplest starting method, within a motor start-up they also provides the lowest temperature rise. Star delta starters allow for starting the motor at a lower voltage, making them suitable for high inertias.
