“…Because the magnitude and phase of auxiliary winding current are different for each motor slip (each instant); so, it is necessary to sense rotor speed with shaft encoder. In this part, the magnitude and the phase of auxiliary winding voltage are determined from a lookup table to eliminate backward mmf only in the steady state for the m N. 2 load. Then, it is compared with proposed method only in the steady state.…”

In the single phase induction motors, backward mmf causes torque and speed pulsations. This paper presents a new method to eliminate the instantaneous backward mmf to improve the performance of the single phase induction motor. In the proposed method a calculated reference current which is in quadrature with main winding current instantaneously, is injected to the auxiliary winding. The "Hilbert transformation" is used for obtaining the reference current of auxiliary winding by using the current of main winding. The proposed control scheme is simple and it does not need any position or speed encoder sensors. Basic system operation and theoretical analysis are discussed and simulation results in comparison with conventional method which uses sinusoidal voltage supply are presented to validate performance of the proposed method.Index Terms -single phase induction motor, main and auxiliary winding, instantaneous backward mmf, Hilbert Transformation, inverter.

“…On the other hand, if only single phase supply system is available, the single phase induction motors (SPIM) are the most common form in the lower horse-power ranges. So, the SPIM has been widely used in households as well as industry [1][2]. In addition, the SPIM has many advantages.…”

“…In this case, an alternative is to make use of static, rotary or electronic single to threephase converters [3][4][5]. On the other hand, one can look at a more contemporary solution based on a three-phase asymmetric induction motor with single-phase feed [1,2,[6][7][8][9][10]. These motors show themselves as extremely advantageous when it comes to cost, especially when these have their cost estimated from the pool of three-phase and single-phase motors, where the value tends to be closer to that of the three-phase of powers greater than 9193.734 W (12.5 hp).…”

An electric network is constituted by generators providing power to various loads. The induction machine is the most common motor in the industrial applications because of its simplicity of construction, its reliability and its low cost. It allows the constant speed applications when it is directly supplied by the network and variable speed ones with the use of power converters. These speed drives induce important harmonic perturbations in the power system and in the motor side. In this context, we are interested by the frequential modelling of the induction machine in order to simulate the line current with its harmonic components. In order to use the induction machine models, it is necessary to identify their parameters and therefore realizing specific and sufficiently informative tests. Several tests of identification are presented in the literature; their differences and their relevance have not been discussed. This study deals with the realization and the comparison of several types of frequential tests (constant voltage, constant V/f, injection of DC current) for induction machine models identification. The comparison of the simulation results with the experimental measurements allows electing the most representative of the induction machine behaviour.
