Abstract
A method for identifying an electric motor includes applying a first predefined current having a first frequency to a terminal of the electric motor. The method further includes calculating a first inductance value of the electric motor at the first frequency. The method includes applying a second predefined d-axis current having a second frequency to the terminal of the electric motor. The method also includes calculating a second inductance value of the electric motor at the second frequency. Further, the method includes obtaining a first deviation value and the second deviation value based on a comparison with a first reference value and a second reference value respectively. Finally, the method includes identifying the electric motor as one of an intended motor or a non-intended motor based on a comparison of each of the first deviation value and the second deviation value with a predefined threshold value.
