PURPOSE: To simplify adjustment and realize highly accurate control by utilizing a neutral network when determining calculated constants to be fetched when driving an induction motor by an inverter. CONSTITUTION: Single phase test means 8l...8n are measured with a plurality of frequencies and currents, and a plurality of leakage inductance values and secondary winding resistance values are obtained. Then, the leakage inductance and secondary winding considered to be correct for an induction motor 2 are estimated by neutral network means 13. With respect to the neutral network means 13, the leakage inductance and the secondary winding resistance measured for various induction motors 2 in advance are used as instructor's values, and the results of learning are set by the learning result setting means 14 of the neutral network. |
