		abstract={This research uses a variable frequency drive (VFD) inverter, a 3 phase electric motor with a power capacity of 0.37 Kw, the Blynk application as a motor on/off controller, and NodeMCU as a communication medium. The tool testing in this study used frequency changes that varied from 10-50 Hz. The results of testing the relationship between changes in frequency and motor speed, where when the frequency is increased from 10-50 Hz, the motor will rotate from 436- 2980 RPM. When the frequency is 10 H z, the voltage on line to neutral is around 144-145 V, while the line to line voltage is 44 V, then the frequency is increased to 50 Hz so the line to neutral and line to line voltage is around 229-230 V. When the frequency varied by 10 Hz, the current in the motor is 0,43 A, while when the frequency is increased to 50 Hz the current in the motor is 0,99 A. When the frequency is 10 Hz the apparent power is 32,7 VA, the input power is 27,8 W, while the motor output power is 24,7 W, when the frequency is increased to 50 Hz the apparent power is 393,3 VA, the input power is 335.2 W, and the motor output power is 298,3 W. The cos phi value ranges from 0,84-0,85 and the motor efficiency value is 89 %.}
