Operation 3 Phase Induction Motor 1 Kw Star Delta System Using Smart Phone

Abstract

In using a 3 phase induction motor there are initial problems. Namely the surge in starting. In most motors induction mainly motors induction three- phase, current starting can reach four to seven times of great current nominal. Horse Power are large, allowing to happen surge currents starting the more substantial and is not be allowed, because it can disrupt the network and can damage the motor it 's own. For this reason, a starting method is needed which can reduce a very large starting current surge. There are several types of starting methods for electric motors. Among them, namely, DOL (direct on line), star-delta, auto transformers, and soft starting. The method that will be used in this research is the starting star-delta method. Star-delta starting is a system starting with running the motor with the configuration of star up first and then converted into a configuration delta for minimizing surge currents. Changes configuration is usually done by using a timer, when the timer has been reached setting the configuration will change. Applying Smartphone via Bluetooth and Arduino Uno R3 to operate a motor Starting way delta by way of sending the instruction in the form of data with a controller that is connected to the motor that. With this method motor operation is easier and safer.
