Abstract
To control sensorless type Brushless DC (BLDC) motors, various back Electromotive Force (EMF) detecting methods have been widely used. In this research, a Finite Elements Method (FEM) model of an 8 pole 12 slot BLDC motor and two kinds of phase-voltage sensing back EMF detecting electrical circuits are coupled to achieve improved and more reliable analysis results. Through this coupled analysis, it becomes possible to analyze the characteristics of the motor and how the electrical circuit affects the motor at the same time. This makes it possible to design high performance embedded motor controllers in the future. An experimental evaluation of the coupled analysis results was also implemented to verify the coupled analysis.
