What are the application fields of motor manufacturing technology?

1. Electrical servo transmission field

In situations where speed control and position control (servo) are required, special motors are increasingly used. Switched reluctance motors, permanent magnet brushless DC motors, stepper motors, permanent magnet AC servo motors, permanent magnet DC motors, etc. have been widely used in CNC machine tools, industrial electrical automation, automatic production lines, industrial robots and other fields. For example, the AC servo motor drive system is used in gravure printing machines, and its high control accuracy achieves extremely high synchronization and coordination, making this printing equipment highly automated, high in registration accuracy, large in printing range, and low in production cost. Energy saving, easy maintenance and other advantages. In industrial sewing machines, with the extensive use of permanent magnet AC servo motor control systems, brushless DC motor control systems, and hybrid stepper motor control systems, industrial sewing machines are becoming more automated, intelligent, complex, integrated, and efficient. , oil-free, high-speed, direct drive direction of rapid development.

2. Household appliances field

Approximately 50 to 100 special motors are used in ordinary households in industrialized countries. The main types of motors are: permanent magnet DC motors, single-phase induction motors, series motors, stepper motors, brushless DC motors, AC servo motors, etc. In order to meet the increasingly higher requirements of users and adapt to the needs of the development of the information age, and to achieve energy-saving, comfortable, networked and intelligent household appliances, the replacement cycle of household appliances is very fast, and high efficiency is proposed for supporting motors. , low noise, low vibration, low price, adjustable speed and intelligent requirements. The motors used in the household appliance industry are being updated, and household appliances driven by high-efficiency permanent magnet brushless DC motors represent the development direction of the household appliance industry. For example, the currently popular high-efficiency and energy-saving variable frequency air conditioners and refrigerators use permanent magnet brushless DC motors to drive their compressors and fans. The washing machine uses a low-noise multi-pole flat permanent magnet brushless DC motor, which can eliminate the original mechanical reducer and directly drive the drum to achieve stepless speed regulation. It is a high-end product among current washing machines. The vacuum cleaner uses a permanent magnet brushless DC motor to replace the original single-phase series motor, which has the advantages of small size, high efficiency, low noise, and long life. Smart home field: such as smart curtains, smart door locks, smart fans, etc.

3. Consumer electronics field

The supporting motors for audio-visual equipment such as record players, tape recorders, VCD video discs and DVD video discs, as well as advanced smart toys and entertainment and fitness equipment are mainly permanent magnet DC motors, printed winding motors, wire-wound disc motors, brushless DC motors, etc. The demand for electronic consumer products such as video recorders, video cameras, and digital cameras is large, and products are updated quickly. The motors equipped with these products are precision-type and difficult to manufacture and process. Especially after entering digitalization, newer and higher requirements are put forward for motors. .

4. Transportation field

Currently, in high-end cars, 40 to 50 electric motors are used to control fuel, improve ride comfort, and display device status, while the number of electric motors on luxury cars can reach more than 80. The motors supporting automotive electrical equipment are mainly Permanent magnet DC motor, permanent magnet stepper motor, brushless DC motor, etc. As a green means of transportation, new energy electric vehicles have received widespread attention in various countries. The motors used to drive electric vehicles are mainly high-power permanent magnet brushless DC motors, permanent magnet synchronous motors, switched reluctance motors, etc. The development trend of this type of motors is high Efficiency, high productivity and intelligence. New energy electric bicycles are mainly driven by wire-wound permanent magnet DC motors and permanent magnet brushless DC motors; in addition, special motors are also widely used in locomotive drive and ship propulsion, such as linear motors used in maglev trains and subways. Train drive.

5. Information processing field

Information technology and the information industry take microelectronics technology as the core, communications and networks as the forerunner, and computers and software as the foundation. Information products and semiconductor manufacturing equipment, electronic devices (including information input, storage, processing, output, transmission, etc.) and communication equipment (such as hard drives, optical disk drives, floppy disk drives, printers, fax machines, copiers, mobile phones) that support the information age etc.) uses a large number of various special motors. Most motors in the information industry are permanent magnet DC motors, brushless DC motors, stepper motors, single-phase induction motors, synchronous motors, linear motors, etc.
