“…Although these aspects have been evaluated in various research, the influence of harmonics generated by PVS on the operation of TIM has not been analyzed. Voltage and frequency variation affects the core losses of TIM (Nour and Thirugnanam, 2017), and voltage variation influences the torque/speed characteristic of TIM (Bonnett et al, 2016). Although these aspects have been evaluated, no research has addressed the influence of voltage variation problems generated by PVS on TIM.…”

This study aims to determine the energy efficiency of three-phase induction motors (TIM) powered when operated with photovoltaic systems (PVS). The environmental advantages of photovoltaic systems (PVS) are very well known. However, there are still challenges related to energy quality, electricity generation instability, failure in frequency regulation, instability in reactive power, and harmonics generation. However, the impact of PVS on TIM efficiency has not been thoroughly explored. This research compares a TIM's electromechanical characteristics and efficiency when powered by a conventional electrical grid versus a PVS. Experimental studies revealed that when powered by the PVS, the TIM experienced increased voltage and higher voltage and current harmonics compared to grid power. These electrical difficulties, attributed to the PVS inverter, resulted in a 2.7% decrease in TIM efficiency compared to grid power. Modeling conducted under actual load variation conditions demonstrated a 2.6% increase in energy consumption when powered by the PVS compared to grid power. Based on these findings, PVS installers are advised to consider the energy quality provided by these systems, as it may affect the efficient operation of TIM, leading to increased energy consumption.

The end leakage inductance is an important component in the primary leakage inductance of the equivalent circuit. In order to calculate the end leakage inductance of a toroidal winding double‐sided linear induction motor (TW‐DSLIM) accurately and quickly, the role of ferromagnetic medium is equated by the method of images, the magnetic flux density in the end space is calculated according to the current density of the rectangular coil, end leakage inductance is obtained by calculating the end leakage magnetic energy, the impact of end leakage inductance on the performance of TW‐DSLIM is investigated, and finally the TW‐DSLIM model is established in finite element analysis to verify the effectiveness of the analytical method.
