Coreless Motor development direction

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: household appliances industry, automobile industry, office furniture, medical industry, military industry, modern agriculture (planting, breeding, warehousing), logistics and other fields are moving towards the direction of automation and intelligence instead of labor, so the application of electrical machinery is also growing in popularity. The future development direction of motor is mainly reflected in the following aspects:


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 Company should pay special attention to the research and development of intelligent motor in the future development.

In recent years, we can see a variety of applications of smart motors, especially during the epidemic, 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, intelligent robots to judge the situation of the epidemic.

It also plays an important role in disaster prevention and rescue, such as: drone fire situation judgment, fire fighting intelligent robot climbing walls (POWER is already producing the smart motor), and intelligent robot underwater exploration in deep water areas.

The application of intelligent motor 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, intelligent animal slaughter. Plant culture: intelligent ventilation, intelligent water spraying, intelligent dehumidification, intelligent fruit picking, intelligent fruit and vegetable sorting and packaging.


Low noise development direction

For motor, 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, precision of parts, fluid mechanics, acoustics, materials, electronics and magnetic field, and then the problem of noise can be solved according to a variety of comprehensive considerations such as simulation experiments. Therefore, in the actual work, to solve the motor noise is a more difficult task for motor research and development personnel, but often motor research and development personnel according to the previous experience to solve the noise. With the continuous development of science and technology and the continuous improvement of requirements, reducing the motor noise to the motor research and development personnel and technology workers continue to give a higher topic.


Flat development direction

In the practical application of motor, in many occasions, it is necessary to choose the motor with a large diameter and a small length (that is, the length of the motor is smaller). For example, the disk-type flat motor produced by POWER is required by customers to have a lower center of gravity of the finished product, which improves the stability of the finished product and reduces the noise during the finished product operation. But if the slenderness ratio is too small, the production technology of the motor is also put forward higher requirements. For the motor with small slenderness ratio, it is more used 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 velocity of the motor, and the better the separation effect.


Development direction of lightweight and miniaturization

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


High efficiency and green environmental protection direction

Motor environmental protection includes the application of motor material recycling rate and motor design efficiency. For the motor design efficiency, the first to determine the measurement standards, the International Electrotechnical Commission (IEC) unified the global motor energy efficiency and measurement standards. Covers US (MMASTER), EU (EuroDEEM) and other motor energy saving platforms. For the application of motor materials recycling rate, the European Union will soon implement the recycling rate of motor materials application (ECO) standard. Our country is also actively promoting environmental protection energy-saving motor.

The world’s high efficiency and energy saving standards for motor will be improved again, and high efficiency and energy saving motor will become a popular 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 Equipment (2022 version)” began to execute, for the production and import of motor, priority should be given to the production and procurement of motor with advanced level of energy efficiency. For our current production of micromotors, there must be countries in the production and import and export of motor energy efficiency grade requirements.


Motor and control system standardization direction development

The standardization of motor and control system has always been the goal pursued by motor and control manufacturers. Standardization brings many benefits to research and development, production, cost control, quality control and other aspects. Motor and control standardization do better is servo motor, exhaust motor and so on.

The standardization of motor includes the standardization of appearance structure and performance of motor. 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. Performance standardization, according to the shape of the motor structure standardization based on the design of the motor performance, to meet the performance requirements of different customers.

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