Design, Simulation and Fabrication of a Permenant Magnet Brush DC Motor

Authors

Abstract

Electrical motor with high performance and maintenance free is very atteractive for the special application in the case of limited energy sources and long operating board. Permenant magnet brush DC motor is very good candidate for such specific applications. In this paper,at first a mathematical model of the motor is persented then, a method for speed control of the motor is developed by using vector (field oriented) control method. The persented method is simulated by PWM switching in Matlab software environment. A control unit is fabricated based on the presented method. moreover the result of experiment is compared with the simulation result. The comparison shows that the presented method had a high efficiency in control of BLDC motor.
