Analysis of main features of large and medium-sized motor products
(1) Large and medium-sized motors need to be tailored Different from the standardized design and production process of micro-motors, small power motors and small motors, large and medium-sized motors need to be rated according to customer's requirements, speed, voltage, bearing form, cooling mode, protection level, torque characteristics, overload capacity, Design and manufacture of dozens of parameters such as load characteristics, grid conditions (power characteristics), use environment, and center height. At the same time, on this basis, experienced technical R&D personnel need to tailor the reliability and safety according to the location and industry characteristics of the motor. (2) Large and medium-sized motor structure and manufacturing process are complex The structure of large and medium-sized motors is related to its type, use, speed, type of protection, ventilation and cooling mode, and installation type. It is generally composed of a plurality of complex structural components, and the structural components have various geometric shapes. The complex structure of large and medium-sized motors determines the complexity of the manufacturing process and the numerous processes. Large and medium-sized motors generally require metal processing processes such as blanking, welding, heat treatment, and spraying; gold processing processes such as car, clamp, planing, milling, boring, grinding, drilling, and inserting; stamping, shearing, riveting, and spot welding. , press-fit and other stamping process links; winding, drawing, dressing, weaving, joints and other electrical processing processes; vacuum pressure immersion paint (VPI), winding anti-corona, coating and other insulation, chemical process links; Balance, assembly, testing and other testing links, each link needs to be equipped with special processing equipment and experienced senior technicians. (3) High and medium-sized motor inspection requirements are high Large and medium-sized motors often require complex inspection procedures to ensure product safety and reliability. Large and medium-sized motors have higher unit prices, and end customers rarely purchase spare motors. However, the safety and reliability of the motors directly affect the safety and reliability of the entire production system. Therefore, the end customers have extremely high requirements for the overall quality of large and medium-sized motors. The production process and a series of inspection procedures before leaving the factory can guarantee the quality and performance of the motor to the utmost extent. Therefore, the manufacturers of large and medium-sized motors have strict requirements for the testing of their production processes, generally including raw material testing (including chemical composition and mechanical property testing). , flaw detection, insulation dielectric strength testing, etc., parts structural size and shape tolerance inspection, semi-finished product inspection, finished product factory test or type test and many other tests. (4) Customers have high requirements for reliability and after-sales service for large and medium-sized motor products In general, the design life of large and medium-sized motors is 20 years, and the design life of large and medium-sized generators is 30 years. Large and medium-sized motors usually need to be repaired once in 1 to 2 years. In some special cases, some motor maintenance cycles last for more than 4 years, even 10 years. Large and medium-sized motors often need to be stable and uninterrupted during the operating cycle until the end of the inspection cycle to stop the relevant inspection and maintenance. Prolonged operation can cause wear, corrosion and deformation of components. Due to the high value of large and medium-sized motors, users often do not reserve spare motors to replace faulty motors. Therefore, in the event of motor failure, the end customer's system will be reduced or shut down. Therefore, the product quality and after-sales service capability of large and medium-sized motor manufacturers, and the rapid repair capability in case of accidental failure, have become one of the main reasons for customers to choose products. Customers have put forward high requirements for the reliability and after-sales service level of large and medium-sized motor products.
