Where is the motor industry going? High-speed direct-drive motors are still mainstream
As the "big heart" of mechanical movement, electric motors appear in our living environment all the time. For example, shopping malls, office buildings, hotels, schools, hospitals, and other places are inseparable from the auxiliary operation of motors. With the rapid development of the industry, the matching of motors in all walks of life is particularly important, that is, high precision, miniaturization and low speed of motors are required.
The high and low precision of the motor mainly depends on the mechanical performance of the motor. High-speed and accurate motor positioning technology is one of the conditions of many industrial controllers. In recent years, the electronics manufacturing industry has developed vigorously, and the development of industrial machinery automation has become a future trend. Therefore, the requirements for motors and motors with high accuracy related to mechanical movements have become increasingly strict.
The miniaturization of motors is a topic that has been discussed for a long time. In fact, there are many types of micromotors, which can be divided into 13 categories. The market has a wide range of application fields. Micromotors can be seen wherever motor drive is required. The manufacturing process of micro-motors is quite complex, involving precision machinery, fine chemicals, magnetic material processing, insulation processing and other process technologies.
On the other hand, conventional motors are usually rotating at high speeds. However, at present, such high-speed traditional motors are difficult to meet the operating requirements of various types of industrial equipment. Used in conjunction with the reduction gear structure. This has caused problems such as tedious procedures, time-consuming and labor-intensive, and equipment maintenance costs, so the development of low-speed motors has become a nail-biting issue.
However, it does not mean that high-speed motors are at an absolute disadvantage. With the continuous emergence of new materials and the continuous improvement of processing technology, high-speed motors have deviated from the original "stereotype." It becomes higher, the noise becomes smaller, and the operation is gradually affected by load changes.
In this regard, regarding the details of what aspects of the high-speed motor still need to be improved, Big Bit sincerely invited the general manager of Hangzhou Three-phase Technology Co., Ltd. Hao He to talk about the high-speed direct-drive motor technology.
The design and application points of high-speed direct-drive motors are introduced from the aspects of electromagnetic analysis, thermal analysis, stress analysis, and bearing selection of high-speed motors. The advantages of high-speed direct-drive and the key design elements of electric spindle motors are introduced with electric spindle motors as examples. .
General Manager Hao He graduated from Zhejiang University with a doctorate in engineering and senior engineer qualifications. He has participated in a number of national 973 projects and national natural science fund projects in the field of high-speed motors, and has obtained dozens of patents / software copyrights in the field of high-speed motors Published more than ten academic papers in related fields in domestic and foreign journals / conferences.
At present, Mr. Hao presides over the industrialization of the company's high-speed motors, servo motors and other product lines.
Hangzhou Three-phase Technology Co., Ltd. is committed to providing high-quality and efficient motor products for production and life, and has been highly recognized by users for import substitution and quality innovation. The company takes "high-speed motor" as its core technology line and is determined to contribute to China's high-speed motor business. The company's main products include: high-speed electric spindle motors, high-speed fan motors, fuel cell air compressor motors, collaborative robot joint motors, etc.
In addition, this symposium is divided into seven topics, including: high-speed and low-noise motor, step-drive single-chip solution, new energy vehicle motor control technology, motor non-sensor FOC vector control, efficient and low-cost motor control solution, motor New schemes of new devices for driving, development trend of mainstream technology of motor control, etc.
