Star-Delta Starter Design for AC Motors
A star/delta starter is an essential component in controlling the commencement of induction/AC motors. This type of starter provides a mechanistic/effective method for minimizing the initial current drawn by the motor during its startup phase. By interfacing the motor windings in a different pattern initially, the starter significantly reduces the starting current compared to a direct-on-line (DOL) start method. This reduces impact on the power supply and defends sensitive equipment from electrical disturbances.
The star-delta starter typically involves a three-phase mechanism that changes the motor windings between a star configuration and a delta configuration. The primary setup reduces the starting current to approximately approximately 1/3 of the full load current, while the ultimate setup allows for full power output during normal operation. The starter also incorporates thermal protection devices to prevent overheating/damage/failure in case of unforeseen events.
