Investigation of Core Loss in Electric Vehicle Induction Motor Using Finite Element Analysis for Performance Enhancement Sachin S, Krishnan Manickavasagam, A T Sriram 2024 3rd International Conference on Power Control and Computing Technologies Icpc2t 2024, 2024 Temperature rise in a 3ϕ, Totally Enclosed Fan Cooled (TEFC)., Squirrel Cage Induction Motor (SCIM) used in Electric Vehicles (EV) is effected by core loss. The temperature rise is a function of core loss and other losses. Since, the core loss components eddy current and hysteresis losses are a function of flux and flux density, Finite Element Method (FEM) is used to obtain average maximum flux density at different loads. Core loss is varying with respect to load and hence temperature rise, resistance value, starting torque to maximum torque $(\\displaystyle \\frac{T_{st}}{T_{\\max}})$ ratio and current drawn at $(\\displaystyle \\frac{T_{st}}{T_{\\max}})$ also varies which is so far assumed constant in reality. The analysis is made on the effect of core loss on SCIM used in EV for performance enhancement. The results reveals that when the variable core loss is considered, temperature rise is reduced and the SCIM rating is enhanced for 20%.
Comparative Analysis to Predict the Temperature Rise in 3ɸ-Squirrel Cage Induction Motor using Lumped Parameter Thermal Model and Finite Element Method for Industrial Applications S. Sachin, Krishnan Manickavasagam, A. T. Sriram Journal of Mines Metals and Fuels, 2023 The 3ɸ - Squirrel Cage Induction Motor (SCIM) used in industrial are prone to thermal breakdown due to its working conditions. Losses in the motor cause rise in temperature. Losses estimation of the 3ɸ - SCIM play a very important role in analyzing the electrical and thermal performances. In this paper a Lumped Parameter Thermal Model (LPTM) and Finite Element Method (FEM) is used to estimate the temperature rise in 3ɸ - SCIM. The temperature rise is obtained considering loss, with load variation between no-load to full load conditions, this enables to analyse the application of induction motor in mines. In addition to that a comparative analysis is carried out between Lumped Parameter Thermal Model (LPTM) and Finite Element Method (FEM) to determine the effective method to estimate temperature rise and determine the relative percentage error in temperature rise at various elements of 3ɸ - SCIM.
A Generalized Mathematical Model to Predict Core Loss of 15kw 3Φ-Squirrel Cage Induction Motor at Various Load for Industrial Applications S. Sachin, Krishnan Manickavasagam, A. T. Sriram Journal of Mines Metals and Fuels, 2023 The demand for effective operation of induction motor has become necessary in industrial, domestic, manufacturing, excavation, mines and many other applications. Losses estimation of the Induction Motor play a very important role in analyzing the electrical and thermal performances. Traditionally copper loss is estimated using load current and core losses is assumed constant, as it is difficult to measure core loss. An additional sensor must be place in air gap of the motor to measure core loss, increasing the complexity and uneconomical. Hence in this paper, a Finite Element Method (FEM) is used to estimate the core losses on 3ɸ - 15kW Squirrel Cage Induction Motor (SCIM) at various load conditions. A generalized mathematical model is needed to predict the core loss of the motor at various load conditions. Hence a generalized mathematical model proposed using regression technique is validated with conventional approach.
Review of physical and mathematical modelling aspects of thermal management of induction motors S Sachin, A T Sriram Journal of Physics Conference Series, 2020 This review paper summarizes the importance of thermal management system and mathematical models used in the prediction of temperature distribution of an induction motor. The lumped parameter thermal network modelling approach is explained in detail with a suitable example. The recent computational methods and their pros and cons on estimating the temperature distribution are discussed. The experimental method on estimating equivalent value for thermal resistance and capacitance is highlighted from the literature. The understanding on physical mechanism of heat transfer is emphasized to recognize thermal flow path for better utilization of cooling techniques. The recent trend in coupling electromagnetic and thermal phenomena is also considered. This study will be helpful on future design of induction motor to meet difficult constraints.
