The hollow cup motor plays an indispensable role in many fields with its unique structural advantages, high-efficiency performance and wide adaptability. This ingeniously designed motor is named after its internal coreless (i.e. “hollow”) rotor structure, which gives it a series of excellent properties such as light weight, high-speed response, low noise and low electromagnetic interference. It is these characteristics that make the hollow cup motor shine in many high-tech and precision control fields and become one of the key forces to promote the progress of modern technology.
- Main features of hollow cup motors:
1) Energy-saving characteristics: The energy conversion efficiency is very high, and its maximum efficiency is generally above 70%, and some products can reach more than 90% (iron core motors are generally 70%).
2) Control characteristics: Rapid starting and braking, extremely fast response, mechanical time constant less than 28 milliseconds, some products can reach less than 10 milliseconds (iron core motors are generally above 100 milliseconds); under high-speed operation within the recommended operating area, the speed can be easily and sensitively adjusted.
3) Driving characteristics: The running stability is very reliable, and the speed fluctuation is very small. As a micro motor, its speed fluctuation can be easily controlled within 2%.
- Seven major application areas of hollow cup motors
In addition, the energy density of hollow cup motors has been greatly improved. Compared with iron core motors of the same power, its weight and volume are reduced by 1/3-1/2. In order to allow users to have a better understanding of hollow brushless motors, the following is a discussion on its main application areas.
Application field 1: electronic digital or office computer peripherals
In the application range of hollow brushless motors, office computers, peripherals and electronic digital are the largest application fields, especially in life, such as: movie cameras, fax machines, printers, copiers, drives, etc.
Application field 2: industrial control field
With the large-scale production and research and development of hollow brushless motors, its technology has become mature, and the drive system made by it has a wider and wider range of use in industrial production, and can even become the mainstream of industrial electric motors. In order to reduce costs and improve operating efficiency in the industry, major manufacturers need to provide different types of motors to meet the needs of different systems. Therefore, hollow brushless motors are increasingly involved in the industrial field. Now they have been involved in printing, metallurgy, automated production lines, textiles, and CNC machine tools.
Application field 3: test equipment field
As we all know, experiments also require a lot of test equipment, and the components of these experimental equipment include hollow brushless motors. This is because the laboratory equipment has very high requirements for motors, not only requiring good controllability, but also requiring very high precision, such as mixers and centrifuges. Since the equipment made of hollow brushless motors can run stably, load and unload flexibly, and is noise-free, its application in the experimental field is becoming more and more extensive.
Application field 4: home appliances and other fields
In life, we use a lot of home appliances, such as variable frequency refrigerators and variable frequency air conditioners. These common variable frequency devices are actually mainly due to the superior performance of hollow brushless motors. The frequency conversion technology it uses is actually the transition of household motors from induction motors to unparalleled motors and controllers, so it can meet the requirements of high comfort, intelligence, low noise, energy saving and environmental protection.
Application field 5: Precision instruments that require fast response
Because the hollow cup motor has gotten rid of the limitation of slow speed regulation of the iron core, its speed start and speed regulation sensitivity are extremely high. In the military field, it can shorten the response time of high-magnification optical drives and improve the hit rate of missiles; in the field of scientific research, it can enable various instruments for collecting data to have automatic fast focusing, high-sensitivity recording and analysis capabilities that were not previously available.
Application field 6: various aerospace vehicles
Because the hollow cup motor has gotten rid of the limitation of the iron core on weight and design space, it not only occupies a small space, but also can be fine-tuned according to the requirements of various aerospace vehicles. From military precision drone motors to common aerospace model generators in life, hollow cup motors can be seen.
Application field 7: Precision instruments requiring convenient use
Due to the high energy conversion rate, small size, light weight, and long endurance of the hollow cup motor, it is very suitable for use in various precision instruments requiring convenient use, such as metal detectors, personal navigators, and engineering instruments for field operations.
With its incomparable technical advantages, the hollow cup motor has shown extraordinary potential and value in seven key application areas. From electronic digital or office computer peripherals to industrial control, from the field of test equipment to the convenient life of smart homes, to the rapid development of precision instruments and drone technology that require rapid response, the hollow cup motor, with its lightweight, high efficiency, rapid response and low noise characteristics, continues to promote technological innovation and industrial upgrading in related industries.
