Influence of non-sinusoidal power supply on the performance of a single-phase capacitor induction motor

Abstract

<span>Harmonic is seen to be an important factor that can influence the performance of different electrical appliances. Earlier studies have regarded the non-sinusoidal power supply as the major source of the harmonic in the induction motors. In this paper, the researcher compared the results generated by a single-phase capacitor induction motor (SIM) using the sinusoidal and non-sinusoidal power supplies. The results in the study could help in comprehensively understanding the impact of the harmonic on the effective performance of the SIM machines when they were powered using a non-sinusoidal power supply. Here, the performance of the SIM when subjected to a maximum load or non-load condition were studied and determined. Furthermore, numerous experimental work was presented to validate the results of the SIM. Power analyses and spectral analysis indicated the actual difference in the overall harmonic wave distortion. It was seen that the current load increased to 89% (i.e., an increase of 11%) when the motor working from the non-sinusoidal source. This investigation highlighted the direct impact of the non-sinusoidal power source on the properties and components of the SIM machine. The vibrations measured under varying conditions and compared the results for the 2 types of power supplies.</span>

Multi-objective optimization of slotted stator switched reluctance motor for electric vehicle application

“…It is crucial to do study on how design parameters and current control affect electric motor performance in to develop methods for improving it. In addition, non-sinusoidal power supply cause harmonics that affect the performance of the motor, as it is necessary to reduce them to improve the dynamic performance of the electric motor [24]. To improve the performance of the machine, fresh configurations are created and optimization techniques are used.…”

Optimizing stator/rotor pole ARC for torque and economy in electric vehicle switched reluctance motors

“…Despite having positive characteristics, SRM has several unavoidable drawbacks, such as high torque ripple and an unbalanced radial force caused by a strong nonlinear step-by-step magnetic field [6]- [8]. In order to enhance the performance of the electrical machinery used in various applications, it is necessary to pay attention to them [9]. Where the impact of topology and current model-related characteristics on the functioning of electrical devices is researched, and created in accordance with guidelines that guarantee the avoidance of faults [10].…”
