With all these advantages, research is still being conducted to improve the performance of the induction motor because it suffers from problems such as low power factor, ripple torque, and low efficiency.
The main objective of this paper is to discuss the increasing of the starting torque and decreasing the ripple torque as well as increasing the efficiency of the squirrel cage induction motor based on specific methodologies carried out on the rotor bar by changing its position in the horizontal and vertical direction as well as implementing the skewing effect on the rotor bar and analyzing the impact of each of these changes on the performance and efficiency by using the finite element method (FEM).

However, poor efficiency and power factor and increased amounts of torque ripple and losses have a significant impact on the performance and hence its efficiency. Therefore, in order to improve the performance of induction machines, the special design
topology for stator and rotor configurations must be investigated and correctly estimated. In this paper, the analysis of the variable geometries of the rotating bars of the cage is presented. More specifically, the influence of dimensions and positions as well as shapes of the rotor rods which have a significant impact on the dynamic performance (developed torque, starting torque, ripple torque, starting current, power factor, harmonics, output power, and efficiency) are investigated. The Finite Element Method (FEM) are used to create the optimum designs as well as calculations are used to optimize the shapes of rotor slots in
order to improve starting performance characteristics such as starting current, initial torque, magnetic flux connection under starting conditions, and efficiency. furthermore, the characteristics of the manufacturing material of the rotor are examined and methods to reduce losses for an induction motor to enhance efficiency are examined. The focus of this paper is on the squirrel cage induction motor (SCIM).

As a consequence, a proposal has been developed for an efficient and affordable remote monitoring system that measures vital signs. This system makes use of a temperature sensor, a dual heart rate and oxygen level sensor, a temperature sensor, two microcontrollers, a UNO as a power supply, and a Node as the main controller. The vital signs are monitored in a non-invasive manner using photoplethysmography technique, and the information is transmitted wirelessly to the individual involved via the Blynk platform, making use of a Wi-Fi device.

Therefore, precise structure optimization of the permanent magnet synchronous machines (PMSMs) is recommended. Consequently, the effect of the main leading design parameters (such as PM arrangement, magnet thickness, pole arc to pole pitch ratio, airgap length as well as the effect of shaft material) for a different number of rotor poles configuration of PMSM can achieve optimum design results in electric motors with economical cost and excellent performance. This paper submits a comparative analysis of different rotor topologies of (PMSM). Moreover, the dynamic performances of the suggested rotor geometry topologies are investigated based on investigation of finite element analysis (FEA). The analysis offers a piece of complete information about the magnetic flux distribution and magnetic flux density over the motor geometry. Gained results from the analysis are used to give a decision for the selection of a suitable PMSM design.

Based on the application and accuracy, modeling processes of electric machines are carried out using different mathematical methods. The most common method for modeling electrical machines is based on solution of differential equations of voltages as well as calculating the time varying self-inductances and the mutual inductances based on the rotor angle. One of the most important features of this method is that the inductance is no long depend on the time varying voltage, which is the major problem facing the conventional model. But the D-Q modeling approach has several problems, the greatest of which is that the voltage applied on stator must be balanced in addition to the fact that the winding are sinusoidal distributed form. Herein this research is focused on build two models of a 3-Φ induction motor (IM) based on the two analytical approaches and compare them to clarify the difference. The results have been shown that the conventional model gives more accurate response when it is applied in both normal and upnormal operation. MATLAB/Simulink softare is used to construct the D-Q and classical abc IM models.
