Micromotor, full name "micromotor", also known as micromotor, refers to the motor with diameter less than 160mm or rated power less than 750W. (Shunchang motor's main product series are 12GA, 13ga
Gear Motor, micromotor with outer diameter of 6-33mm, and reducer with outer diameter of 12-37mm). Micromotor is commonly used in control system or transmission mechanical load to realize the functions of electromechanical signal or energy detection, analytical calculation, amplification, execution or conversion.
There are many kinds of micromotors, which can be roughly divided into 13 categories:
Dc Motor, AC motor, synchro motor, stepper motor, resolver, shaft encoder, AC /
DC Motor, tachogenerator, inductosyn, linear motor, piezoelectric motor, motor unit and other special motors.
Brushless DC motor: it is the fastest growing variety in the
Micro Motor industry in recent years. With the "small, light and thin" audio-visual products, the mute of household appliances and the increasing demand for luxury cars, the demand for brushless DC motor is increasing rapidly. It has the advantages of high reliability, high efficiency, long service life and convenient speed regulation by replacing electric brush and commutator with electronic commutation. All countries have accelerated the speed of developing new products and the strength of occupying the market. Many companies in Japan have applied brushless DC motors to digital cameras, mini tape recorders, cameras, printers, storage drivers, mobile phones, automobile air conditioners, washing machines, vacuum cleaners, electric vehicles and heart pumps.
Linear motor: it has the advantages of simple structure, non-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 field of linear stepper motor is more and more widely. Major companies in the world are vigorously researching and developing new products and developing application fields. Japanese companies such as tamakawa, Matsushita, yamasawa and servo also have linear motor products. At present, linear motors have been used in many automation equipment, such as high-speed punch, high-speed cutting machine, satellite antenna, magnetic head driver, plotter, printer, copier, scanner and electric door.
High speed hydrodynamic bearing motor: in order to meet the miniaturization requirements of electronic products, the development of small motor to high speed is a trend of technological development, such as the rapid increase of storage density of computer peripherals, its supporting spindle brushless motor runs at a high speed of more than 8000r / min, and many small and micro electric machines even operate at a high speed of more than 20000 R / min. in order to ensure the low noise of small motor at high speed, and ensure the safety of small motor Many Japanese companies have developed and produced high-speed hydrodynamic bearing motors, including air bearing and liquid bearing. At present, there are many applications of aerodynamic bearing, especially for DVD, HDD, CD-ROM and other spindle motors which require low noise and small jitter under high-speed operation.
Micro motors: micro computers, pinball machines, health care, beauty massage, toys for the elderly and children, mobile communications and other fields are widely used, such as mobile phones, advanced toy cars, and micro motors for electric toothbrushes. In recent years, the demand for micro motors has increased rapidly, especially for small motors with diameters of 3mm to 6mm (hollow and solid) and button motors with diameters of 8mm to 1mm The demand for 2 mm has increased dramatically. PC, household, elderly health massage and toys, women's bodybuilding massage, children's intelligent toys and small household appliances also need a large number of micro motors, most of these products are consumer products. Shunchang motor's main product series are 12GA, 13ga gear reducer, micromotor with outer diameter of 6-33mm and reducer with outer diameter of 12-37mm
Ultra micro motor: the medical field is the most representative field of the application of micro mechanical and electronic technology. Micro invasive endoscopic diagnosis and treatment, precision microsurgical operation machinery and micro robot all need ultra micro motor with small volume, large power and high flexibility. Micromotor is the key executive and driving component of MEMS. With the continuous improvement and maturity of Micromotor manufacturing level, its output and application fields are expanding. Its market potential is huge, and it is expected to become a new economic growth point.
Sheet motor: with the development of electronic products in the direction of miniaturization, lightweight and thinness, the supporting small motor is also required to develop in the direction of "micro, light and thin", so the development of sheet motor has become an inevitable trend. The principle of sheet motor is not much different from that of traditional DC motor. Many companies in Japan have produced sheet motors, which have been widely used in soft, hard, CD-ROM drives, Walkman, tape recorders, video recorders, video cameras, digital cameras, mobile communications and micro medical devices.
Micromotor integrates the high-tech industry of stepping motor, microelectronics, power electronics, computer, automatic control, precision machinery, new materials and other disciplines, especially the application of electronic technology and new material technology promotes the technological progress of micromotor.
