Micro-motors effectively promote the advancement of micro-motor technology
In the past two years, the use of micro-motors has increased significantly. Due to the rapid development of the terminal products and the continuous updating of the models, the functional design, development and production of the motors are constantly being updated. Therefore, in the future, the function of the high-end motor should be measured by the development of new products and the actual needs of the manufacturers. The potential of the entire international market is enormous.
Micro-motor market analysis in recent years
Micromotor, the full name "micromotor", refers to a motor with a diameter of less than 160mm or a rated power of less than 750W. Micromotors are commonly used in control systems or transmission mechanical loads to perform functions such as detection, resolution, amplification, execution or conversion of electromechanical signals or energy.
There are many types of micro-motors, which can be roughly divided into DC motor, AC motor, self-aligning motor, stepping motor, rotary transformer, shaft encoder, AC/DC motor, tachogenerator, inductive synchronizer, linear motor, and pressure. 13 categories of electric motors, motor units and other special motors.
DC brushless motor: It is the fastest growing variety in the small motor industry in recent years. With the “small, light and thin” audio-visual products and the quieting of home appliances and the increasing demand for luxury cars, DC brushless motors are in rapid demand. increase. It replaces brushes and commutators with electronic commutation, which has the advantages of high reliability, high efficiency, long life and convenient speed regulation. Countries have accelerated the speed of developing new products and occupying the market. Many Japanese companies have applied DC brushless motors to digital cameras, mini-recorders, cameras, printers, storage drives, mobile phones, and automotive air conditioners, washing machines, vacuum cleaners, electric vehicles, and heart pumps.
Linear motor: It has the advantages of simple structure, no contact movement, low noise, high speed and precision, easy control, convenient maintenance and high reliability. With the continuous innovation of industrial automation level, the application fields of linear stepping motors are becoming more and more extensive. Major companies all over the world are vigorously researching and developing new products and developing application fields. Japan's Tamagawa, Matsushita, Yamashita, servo and other companies also have linear motor products. Linear motors have been used in many automation equipment, such as high-speed punching machines, high-speed cutting machines, satellite antennas, magnetic head drives, plotters, printers, copiers, scanners and electric gates.
High-speed dynamic pressure bearing motor: In order to meet the miniaturization requirements of electronic products, the development of small motors to high speed is a technological development trend. For example, the storage density of computer peripherals is rapidly increasing, and the matching spindle brushless motor is above 8000r/min. High-speed operation, many small motors even run above 20000r/min, in order to ensure low noise of small motors under high-speed operation, and to ensure stable operation, small jitter and long life under high-speed rotation, many companies in Japan have developed Production of high-speed dynamic pressure bearing motors, dynamic pressure bearings are available in air and liquid dynamic pressure bearings. At present, there are many air dynamic pressure bearings, especially suitable for high-speed operation, requiring small noise, small jitter, such as DVD, HDD, CD-ROM and other spindle motors.
Micro-miniature motors: Micro-miniature motors, such as small computers, ball machines, health care, beauty massage, elderly and children's toys, mobile communications, etc., such as mobile phones, high-end toy cars, and micro-motors for electric toothbrushes. Demand has increased rapidly, especially for small motors with diameters ranging from 3mm to 6mm (hollow and solid) and button motors ranging from 8mm to 12mm. PCs, households, health massages and toys for the elderly, women's body massage, children's smart toys and small appliances also require a large number of micro-motors, most of which are consumer products.
Ultra-micro motor: The medical field is the most representative field of micro-mechanical and electronic technology applications. Micro-traumatic endoscopic diagnosis, precision microsurgery machines and micro-robots all require a small size and high power. Highly compliant ultra-miniature small motor. Ultra-micro motor is the key execution and driving component of micro-mechanical electronic system. With the continuous improvement and maturity of ultra-micro motor manufacturing, its production and application fields are expanding, and its market potential is huge, which is expected to become a new economic growth point.
Chip motor: With the development of electronic products in the direction of miniaturization, light weight and thinness, the supporting small motors are also required to develop in the direction of “micro, light and thin”, and the development of chip motors has become an inevitable trend. The principle of a chip motor is not much different from that of a conventional DC motor. A number of companies in Japan have produced chip motors and have been widely used in soft and hard drives, compact disc drives, walkmans, recorders, video recorders, camcorders, digital cameras, mobile communications, and micro medical devices.
Micro-motors integrates high-tech industries such as stepper motors, microelectronics, power electronics, computers, automatic control, precision machinery, new materials, etc., especially the application of electronic technology and new materials technology promotes the advancement of micro-motor technology. .
