“…Although the actual supply voltage system is asymmetric and non-sinusoidal and stator and rotor windings of the asynchronous motor are not always symmetrical, the methods for asynchronous machines modeling, when the stator and the rotor windings are symmetrical and the power supply system is sinusoidal, are widely used. The works on the asynchronous machines modeling can be a proof of the same [8][9][10][11][12][13]. The mathematical models, obtained with the help of these methods, allow to investigate dynamic processes in electric drives with asynchronous motors and to study the operating modes of electric machines under the condition of symmetry of the stator and the rotor windings and with a high-quality power supply system of the electric the mathematical tool and the algorithm of its application are given only conceptually in [23][24].…”

This article is devoted to development of a method for calculating the parameters of an asynchronous motor of an electric locomotive with asymmetrical windings of stator and rotor. A method for determining self and mutual inductances of the stator and rotor phases of an asynchronous motor with asymmetric windings and their relations to mechanical variables is proposed. It is based on comparing two equations of stored magnetic energy, one equation calculated through induction, magnetic field strength and geometrical dimensions and another equation calculated through the parameters of the motor circuits. It is shown that the obtained solutions correspond to the previously existing methods, but they give the additional possibilities in mathematical modeling. The proposed technical solution allows higher accuracy developing of a mathematical model of a drive with an asynchronous motor having asymmetrical stator and rotor windings for studying dynamic processes during the operation of the specified drive, in particular, the drive of auxiliary machines for electric locomotive, where an asynchronous motor with asymmetrical stator windings is used as a phase release.

“…However, when the magnetizing inductance starts to saturate, an error occurs with the singleaxis sinusoidal excitation. This phenomenon has been studied in [15]. Firstly, the chord-slope inductance L M is pulsating in the single-phase sinusoidal excitation while it is constant in the three-phase excitation.…”

This paper compares two different standstill identification schemes for the induction motor (IM) parameters. The schemes apply sinusoidal-excitation tests and DC-decay tests. Magnetic saturation of the motor is taken into account. The sensitivity of the parameter estimation to the stator resistance errors and the voltage errors is studied. Simulation results using a 2.2-kW IM drive are presented. Index Terms-Induction motor drives, parameter identification, saturation characteristics.

Modern electric drives use a self-commissioning procedure to precisely identify motor parameters for achieving high-performance control. Typically, the induction motor magnetizing curve is identified using no-load rotational test. However, some applications necessitate the electric drive to identify the magnetizing curve at standstill conditions. As one of the well-known standstill approaches, the traditional flux integration exhibits several practical problems. Any imperfection in measured current, estimated stator resistance, and dead-time compensation directly affects the accuracy of the estimated magnetizing curve because of error accumulation in open-loop integration. This paper proposes a robust yet simple solution against those practical concerns. It can identify the magnetizing curve without using any dead-time compensation and stator resistance. Only industry-standard dc-link voltage and phase current measurements are used. Its superior features are experimentally verified on a number of motors and the results are confirmed by no-load rotational test results. Its robustness against current offset and extra longer integration duration is also proved.
