Design and Evaluation of a MATLAB SIMULINK Block of Permanent Magnet Brushless DC Motor

Abstract

Electronically commutated Permanent Magnet Brushless DC (PMBLDC) Motors are increasingly the preferred choice in many applications, especially in the field of motor control technology. As these kinds of motors have unique constructional features and huge applications, a well-designed simulation model has to be needed for better understanding and research purposes. At present MATLAB SIMULINK is very much popular and usable platform for simulation. But there is no specified SIMULINK block of PMBLDC motor in MATLAB SIMULINK library up to 2018 (i.e. MATLAB SIMULINK version R2018b). This paper focuses on to this point to design a simulink block of PMBLDC Motor in MATLAB SIMULINK environment. A pulse amplitude modulated PMBLDC motor drive is also designed to monitor the performance of the designed PMBLDC motor simulink block. Both the steady state and transient characteristics are considered to analysis the performance of designed simulink block of PMBLDC motor which is found satisfactory. This PMBLDC motor simulink block can be customized to design any kinds of PMBLDC motor drive in MATLAB SIMULINK environment. The designed simuilnk block is also possible to add in MATLAB SIMULINK library.
