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