    Motor development direction

    2023-03-17 14:39:30 159

    With the continuous progress of society, the continuous development of high technology (especially the application of AI technology), and people's continuous pursuit of a better life, the application of micromotors is more and more extensive. For example, the household appliances industry, automobile industry, office furniture, medical industry, military industry, modern agriculture (planting, breeding, warehousing), logistics, and other fields are developing towards automation and intelligence instead of the labor force, so the application of motor is also growing in popularity. The future development direction of the electric machine is mainly reflected in the following aspects:

    1. Intelligent development direction

    With the world's equipment manufacturing industry, production of industrial and agricultural products towards the direction of action accuracy, control accuracy, action speed, and information accuracy, the motor drive system must have self-judgment, self-protection, self-speed regulation, 5G+ remote control, and other functions, so intelligent motor must be an important development trend in the future. POWER MOTOR pays special attention to the research and development of intelligent motors in future development.

    In recent years, we can see a variety of applications of smart motors, especially during the epidemic period. Smart devices have played an important role in our fight against the epidemic, such as intelligent robots to detect body temperature, intelligent robots to deliver goods, and intelligent robots to judge the situation of the epidemic.

    It also plays an important role in disaster prevention and rescue, such as UAV fire judgment, firefighting intelligent robot climbing walls (POWER is already producing the intelligent motor), and underwater exploration of intelligent robots in deep water areas.

    The application of intelligent motors in modern agriculture is very wide, such as animal breeding: intelligent feeding (according to the different growth stages of the animal to provide different amounts and different nutritional elements of food), animal delivery artificial robot midwifery, and intelligent animal slaughter. In the plant culture: intelligent ventilation, intelligent water, intelligent dehumidification, intelligent fruit picking, fruit, vegetable intelligent sorting, and packaging, etc.

    2. Low noise development direction

    For motors, there are two main sources of motor noise: mechanical noise on the one hand, and electromagnetic noise on the other hand. In many motor applications, customers have high requirements for motor noise. Reducing the noise of the motor system needs to be considered in many aspects. It is a comprehensive study of mechanical structure, dynamic balance of rotating parts, the precision of parts, fluid mechanics, acoustics, materials, electronics, and magnetic field, and then according to a variety of simulation experiments and other comprehensive considerations to solve the problem of noise. Therefore, in the actual work, solving the motor noise is a more difficult task for the motor research and development personnel, but often the motor research and development personnel according to the previous experience solve the noise. With the continuous development of science and technology and the continuous improvement of requirements, reducing motor noise to motor R & D personnel and scientific and technological workers continue to give a higher topic.

    3. Flat development direction

    In the practical application of motors, on many occasions in the selection of a motor need to design the motor diameter is large but the length is small (that is, the length is small), such as the current POWER production of a disc flat motor, customer requirements of the finished product center of gravity is low, improve the stability of the finished product operation process, reduce the noise of the finished product operation process. But if the slenderness ratio is too small, it also puts forward higher requirements for the production process of the motor. For the motor with a small slenderness ratio, it is applied more in the centrifugal separator. Under the condition of a certain motor speed (angular velocity), the smaller the slenderness ratio of the motor, the greater the linear speed of the motor, and the better the separation effect.

    4. The development direction of lightweight and miniaturization

    Lightweight and miniaturization are important development directions of motor design, such as motors for aerospace applications, automotive motors, UAV motors, medical equipment motors, etc., which have higher requirements for the weight and volume of motors. To achieve the goal of lightweight and miniaturization of the motor, that is, the weight and volume of the motor per unit of power are reduced, the motor design engineer should optimize the design in the design process, and apply advanced technology and high-quality materials. Because the electrical conductivity of copper is about 40% higher than that of aluminum, the application ratio of copper and iron should be increased, and the cast aluminum rotor can be changed to cast copper. For motor core and magnetic steel, higher-level materials are also needed, which greatly improves its conductivity and magnetism, but the cost of motor materials will increase after this optimization. In addition, for the miniaturized motor, there are higher production process requirements.

    5. High-efficiency green environmental protection direction development

    Motor environmental protection includes the application of motor materials recycling rate and motor design efficiency. For motor design efficiency, the first thing to determine the measurement standards, the International Electrotechnical Commission (IEC) unified the global motor energy efficiency and measurement standards. It covers the United States (MASTER), European Union (EuroDEEM), and other motor energy-saving platforms. For the application recycling rate of motor materials, the European Union is about to implement the recycling rate (ECO) standard of motor materials application. China is also actively promoting environmental protection and energy-saving motor.

    The world's high efficiency and energy-saving standards for the motor will be improved again, and high efficiency and energy-saving motors may become a boom in the market demand. On January 1, 2023, the National Development and Reform Commission and other 5 departments issued the "Advanced Level of Energy Efficiency, Energy saving Level and Access Level of Key

    Energy Use Products and equipment (2022 version)" and began to implement, for the production and import of motors, priority should be given to the production and purchase of motors with an advanced level of energy efficiency. For our current production of micromotors, there must be countries on production, import, and export of motor energy level requirements.

    6. The direction of standardization of the motor and control system

    The standardization of motor and control systems has always been the goal pursued by motor and control manufacturers. Standardization brings many benefits to R&D, production, cost control, quality control, and other aspects. Motor and control standardization do better in servo motors, exhaust motors, and so on.

    Motor standardization includes appearance structure standardization and motor performance standardization. The standardization of shape structure brings the standardization of parts, and the standardization of parts will bring the standardization of parts production and the standardization of motor production. The standardization of performance can be based on the standardization of the shape structure of the motor. The performance of the motor can be designed in sections to meet the performance needs of different customers.

    The standardization of the control system includes the standardization of hardware and software and the standardization of the interface. Therefore, for the control system, the first is the standardization of hardware and interface, based on the standardization of hardware and interface, software modules can be designed according to the market demand, to meet the functional needs of different customers.

    Summary: The above is the current development direction of the motor, with the continuous development of society, people's demand is constantly improving, and the demand is constantly changing, as the motor manufacturer, constantly insight into the market demand, according to the market demand adjust the development and production direction.In the market competition, based on an invincible position.
