“…The air gap of the machine is modelled by a smooth inner rotating cylinder and a grooved stationary surface. On the base of the Taylor, the number can be calculated as the Nusselt number, which is necessary for the specification of the heat transfer coefficient (16). The Equation ( 17) expresses the dimensionless Taylor number as a function of the Reynolds number (18).…”

The primary objective of the research presented in this paper was to design a methodology for analyzing the thermal field of an induction motor that would be of higher fidelity but less time- and cost-consuming and that would deal with air-cooled induction motors of all sizes. The complexity of the simulation is increased by the geometric asymmetry and by the asymmetric character of flow cooling the motor casing caused by the fan’s rotation. This increases demand, especially on computational resources, as creating a simplified numerical model using symmetry boundary conditions is impossible. The new methodology uses the existing findings from many partial articles and literature, which are modified into more accurate relationships suitable for predicting the external thermal field of induction motors. That way, we do not have to solve the thermal field by the conjugate heat transfer method, and it is possible to assess temperature gradients over the entire range. Furthermore, a new relationship between shear strain rate and thermal contact conductivity has been discovered that allows solving heat transfer of fluid adjacent to the internal walls of an induction motor at any location. That approach has not yet been published in the literature, so it can be considered a new method to simplify heat transfer simulation. An experimentally validated new methodology of the induction motor was performed. The so-called digital twin will be used for the virtual optimization of the new designs concerning minimizing losses and maximizing efficiency.

This paper discusses the phenomena of the axial direction of the induction motor with the skewed axially non-uniform distribution of magnetic flux densities rotor bars is produced by a different phase angle of and losses in a 3-phase squirrel cage induction motor of the flux density made by the rotor bar Currents along which the rotor bars are skewed. A 2-dimensional complex the axial direction when the stator is taken as the finite element method taking account of the effects of the skewed rotor bars i s utilized for the analysis of reference* as shown in Fig. '' characteristies such as copper and iron losses and the On the other hand, the non-uniform distribution loss distributions are examined. The summing up values Pattern of the resultant flux density varies according of non-uniform losses resulted from the finite element to the motor speed, because the phase angle of the analysis are compared with measurement values.bar currents depends on its impedance at an operating Index Terms-Induction motors. skew effect. finite element methods, losses
