Simulation and Analysis of a 3-Phase Induction Motor and a Brushless DC Motor Using Simulink

Abstract

This paper proposes the Simulation and Analysis of a 3-Phase Induction Motor and a Brushless DC Motor using the MATLAB/Simulink environment. In this paper a three-phase squirrel cage induction motor is simulated under different load conditions and the characteristic graphs of this motor are obtained. Induction motors are the most widely used motor drive and thus the results obtained are important in understanding and designing the motor for precise command and control. In a BLDC motor, the torque characteristic plays an important role in the design and analysis of BLDC motor drive systems which is used in industries for automated vehicles and collaborative robots. Therefore, it is necessary to predict the precise value of torque, which is determined by the characteristics obtained as a result of simulating back EMF vs time for the BLDC motor addressed in this paper. Both these motors are most widely used and find their application in various industries such as Automotive industry, Automobile sector, Aerospace, Pulp and Paper industry, Medical, consumer, Induction Automation Equipment and Instrumentation
