The data collection method in this study is the monitoring method. by varying the value of the voltage from 250 V, 300 V, 350 V and 380 V. The results showed that the control circuit for the influence of the star (Y)-triangle (?) supply voltage of a three-phase induction motor can work well at a voltage of 380 V. Motor starting current electricity using the star starting method (Y) 6.5 A with a nominal current of 1.5 A and a power of 3030.87 Watt- The triangular starting current method (?) is 20.5 A and a nominal current of 12.5 A and a power of 6100.98 Watt, obtained RPM starting 2977 module rpm, tacho meter rpm 3130 RPM with a speed difference of 153 RPM. This shows that this star delta circuit is to minimize the starting inrush current, where the motor requires a large initial torque when starting, and there is no overshoot in all circuits during the study.} }
