Abstract：The philosophy of Marxism is the scientific world view and methodology. Philosophical way of thinking has been used consciously or unconsciously by researchers of electrical engineering. After analyzing the necessity of employing the philosophy of Marxism in dealing with motor fault, this paper analyzes the following aspects: the causal relationship between motor failure and motor overload or short circuit failure because of the heat generated by motor; the development of sensors to detect electrical short- circuit fault is explored by means of the philosophical relationship between theory and practice; the virtual digital platform of motor and electrical system abandons the traditional linear casual way of thinking; the development process of switched reluctance motor drive system mirrors laws of movement, change and development of objects, and reflects the view of development. Finally, the author concludes that marxist philosophy of thinking can help motor and electrical engineers and technical personnel solve technical problems, upgrade the development of motor and electrical equipment to a new level.
