Performance Analysis of Induction Motor using Ansys

Abstract

Squirrel cage Induction motors are useful in constant speed and variable frequency drives applications because they are self starting and have high overload capacity. Though they are self starting, their design limits corresponding to torque should be large to meet the actual load conditions. To get optimum performance of motor, it needs unique design characteristics. Design of machines is a time consuming process. Proper methods are required for designing. ANSYS software is being used in recent times for designing electrical machines. In this paper, RMxprt tool box is used to design induction motor and its performance is analyzed using ANSYS Maxwell. In RMxprt, the induction motor's geometric model is designed and analyzed .In this model the machine rating is of 1100W with a rated speed of 1450 rpm and with rated voltage of 330V. With the help of this design, squirrel cage induction motor performance in terms of torque, power, efficiency, voltage and current can be analyzed for any rating.
