Modeling and Dynamic Performance Analysis of PMBLDC Motor


Permanent Magnet Brushless DC (PMBLDC) motors are one of the electricaldrives that are rapidly gaining popularity, due to their high efficiency, good dynamicresponse, high mechanical power density, simplicity, cost effectiveness and lowmaintenance.In this paper, the state-space technique is presented and used for analyzing thedynamic performance of PMBLDC motor. The method is based on the formulation ofstate equations from the mathematical model of the motor and conversion of them intoa set of linear algebraic equations by the use of trapezoidal rule of integration. Thesimulation of the motor has been done using the software package Matlab.
