Abstract: Induction motor is singly excited motor, which is very simple and compact. This motor is extremely rugged in construction and most reliable with low cost construction. Robustness and reliability made the squirrel-cage induction motor the most used motor in industrial and domestic applications. . Despite the emergence of new types of electric machines, the squirrel-cage induction motor remains the dominant one based on geometric dimensions. In this paper a model was developed in the 2d and 3d Maxwell program by which the transient process at the motor start-up was calculated for different features especially temperature. For detailed and accurate analysis of motor performance in faulty conditions, an accurate model for the motor in which all conditions can be considered is of extreme importance. Thermal analysis is achieved based on a precise knowledge of the test motor geometry, materials, and heat sources (losses). This work will help the induction motor designer in predicting the thermal state of induction motor when modifying the frame, without needing manufacturing and testing expensive prototype motor. In this work the model of induction motor is presented in 2d and its designing is understood with the variation of currents and various characteristics curves have been studied.Download PDF
