An Expert System for Design of Output Parameters for BLDC Motor

Abstract

Classical DC motors are no doubt good and simple but inefficient in some ways. Although brushed dc motors possess good control characteristics and ruggedness, however their performance and applications are inhibited due to sparking and commutation problems. Permanent Magnet Brushless DC (BLDC) motors overcomes the limitations, which are now competing with many other types of motors in the world industries application. For low and medium power applications, BLDC motors are often the main option due to its recognized advantage such as having no commutator, more efficient, needless maintenance, smaller in size and can operate at higher speeds than conventional motors. This concept (Expert System) does not have the heuristic selection of design variables and does not need much manual design iterations. The design cycle is significantly reduced which has advantage over the traditional and other existing design method. Graphical User Interface (GUI) adds wide flexibility to user for designing BLDC motors for different application domains.
