Research On The Application Of Modern Quality Management In Permanent Magnet Motor Manufacture

The quality of products is an important flag to symbolize the developing level of the productivity, technology and economics in a country. With the advancement of the society and the development of science and technology, the requirement to the manufacturing quality of products become higher and higher. In our country, the technique of researching and developing is gradually mature in permanent magnet motor and it is applied widely. However, in the manufacture process, there are many quality problems, such as, the insufficient stability judgment of manufacture process, the big fluctuation of stator quality and the low employee quality consciousness. How to raise the permanent magnet motor manufacture quality, reduce cost, and advance employee quality consciousness, it is already the key that electric motor manufacturing enterprise exists in sustained changeful environment.On the base of reviewing the relevant status quo's researches, the paper firstly reviews the history of the three developing stages of Quality Inspection, Statistic Quality Control and Total Quality Management, sums up the basic ideas of quality management and it impetus to launch of quality assurance activities, and analyzes the main work and harvest to implement modern quality management in our country. Basis on analyzing the reason of product management variation and the introduction of common quality control methods, some key problems about statistical quality control are elaborately discussed, developing a method for deciding the quality control line, setting up a mathematical model that based on the sampling plan of multi-variation of product quality. The limitation of 3σcriterion in traditional statistical quality control is analyzes, the concept of 6σcriterion in modern quality control is introduced, and the DMAIC implementing method is elaborately expatiated. In the analyzing of example, the quality condition of transverse flux permanent magnet motor in manufacture process is analyzing, finding out questions. Continuous improvement is used to resolve the problem of complex process in stator manufacturing, the theory of fuzzy diagnosis is applied to discriminate the manufacture process condition of permanent magnet material quality control chart, stator mangling reasons are analyzes, and applies some improvement proposals. It have made the permanent magnet motor manufacture quality notable rise, prevented the hidden trouble of quality, and cut down the unnecessary dissipationThe main body of this paper research work can enrich the research so far to the manufacture process quality of permanent magnet motor, especially base on the combination of quantitative and qualitative method, analyzing the problem of permanent magnet motor in manufacture process, it is the perfecting and complement to present manufacture management method of permanent magnet motor. Though it researches on the permanent magnet motor, the method and idea analyzing problems, solving problems have certain references significance for our electric motor manufacturing enterprise, even for production manufacture enterprise in quality management.
