To achieve accurate directional of the rotor flux in the asynchronous motor vector control and improve the performance of weakening control, this paper presents a line identification asynchronous motor mutual inductance curve approach. Through the analysis of asynchronous motor equivalent model, we know that by applying a single axial test signal can be measured mutual inductance curve. TMS320F2812-based controller with a drive and a 5.5 kW motor tests. Experimental results show that the method is effective and can more accurately measure the mutual induction motor curve.
