This thesis, design and create sets of experimental three-phase induction motor driven by inverter brands choose to use the ATV312H075M2 version of Schneider coordinates input voltage is 220-240 volts, 0.75 kW to test for usability studies by applying inverter to drive three-phase induction motor that is the size that the inverter can be controlled. 4. operation mode is Constant Torque, Torque control Sensorless flux vector Variable, and Energy saving, and test drive 5 load is the load size 0.4 kW, wireless condition rotated driving the Bora River fan size 0.4 kW, driving a fly living conditions size 0.75 kW, driving a DC load rotation conditions.Until the generators size 0.75 kW and 1.5 kW, water pump driven load test results, saves are in tables and graphs to compare the change of pressure per frequency. The stream inputs and outputs Input voltage and output voltage. Power input and output power The rotation speed of the motor. The torque of the motor, and the motor's performance.
