Hollow cup reduction motors have high energy conversion efficiency, and the maximum efficiency is generally above 70%, and some can reach more than 90% (iron core reduction motors are generally below 50%). Starting and braking are fast, and the response is extremely fast. The mechanical time constant is less than 28 milliseconds, and some products can reach less than 10 milliseconds (iron core reduction motors are generally above 100 milliseconds); under high-speed operation in the recommended operating area, the speed can be sensitively adjusted, and the fluctuation can be easily controlled within 2%. In addition, compared with iron core reduction motors of the same power, its weight and volume are reduced by 1/3-1/2. In order to allow users to have more understanding of hollow cup 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 Coreless brushless motors, office computers, peripherals and electronic digital are the largest number of 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 chaoya hollow cup brushless motors, its technology has become mature, and its scope of use in industrial production has become wider and wider, and it can even become the mainstream of industrial electric motors. In order to reduce costs and improve operating efficiency in industry, major manufacturers need to provide motors of different models to meet the needs of different systems. Therefore, hollow cup brushless motors are more and more involved in the industrial field. Now it has involved 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 cup brushless motors. This is because the equipment used in the laboratory has very high requirements for motors, not only requiring good controllability, but also requiring very high precision, such as mixers, centrifuges, etc. Since the equipment made of hollow cup 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 area 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 cup brushless motors. The variable frequency technology it uses is actually the transition of the reduction motor used in the home from the induction reduction motor to the dual reduction motor and controller, so it can meet the requirements of high comfort, intelligence, low noise, energy saving and environmental protection.
Application area 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 area Six: Various aerospace vehicles
Since the coreless motor is free from the weight and design space restrictions of the iron core, 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, coreless motors can be seen.
Application field seven: Precision instruments that require convenient use
Due to the high energy conversion rate, small size, light weight, and strong endurance of the coreless motor, it is very suitable for use in various precision instruments that require convenient use, such as metal detectors, personal navigators, and engineering instruments for field operations.
