3 thoughts on “What are the applications of motor?”

  1. The field of electric motor applications is very widely used in the following seven areas:

    The field of electrical servo transmission in the field of electrical servo transmission (servo) in the field of electrical servo transmission, and the application of special motors is becoming more and more widely used. Switching magnetic motors, permanent magnetic brushless DC motors, stepping motors, permanent magnet AC servo motors, permanent magnet DC motors, etc. are all in CNC machine tools, industrial electrical automation, automatic production lines, industrial robots, and various military and civilian equipment. The field has been widely used. For example, the application of the AC servo motor driving system is applied to the concave printing machine, and its high control accuracy achieves extremely high synchronous coordination, so that this printing equipment has high degree of automation, high accuracy of accuracy, large printed scope, low production costs, and low production costs, and low production costs. Save energy and convenient maintenance. In the industrial sewing machine, with the large number of use of permanent magnet AC servo motor control system, brushless DC motor control system, hybrid steaming motor control system, the industrial sewing machine is automated, intelligent, compounded, integrated, and efficient , The rapid development of non -hydraulic, high -speed, and direct driving direction.
    The information technology and information industry in the field of information processing are based on microelectronics technology, communication and networks, and computers and software. The semiconductor manufacturing equipment, electronic devices (including information input, storage, processing, output, transmission, transmission and other links) in the age of information products and supporting information, as well as communication equipment (such as hard disk drives, disc drives, floppy drives, printers, fax machines, photocopters, mobile phones, mobile phones Wait) use a large number of various special motors. The information industry is highly valued at home and abroad, and has obtained high -speed development. The demand for special motors in the information field is about 1.5 billion units (sets). Most of these motors are permanent magnetic DC motors, brushless DC, Electric, stepping motors, single -phase induction motors, synchronous motors, linear motors, etc.
    The transportation field. At present, in high -end cars, in order to control fuels and improve the comfort of ride -ride and display device status, 40 ~ 50 motors should be used, and more than 80 motors on luxury cars can be used. Automotive electrical equipment supporting motors are mainly permanent Magnet DC motors, permanent magnet step into motor, brushless DC motors, etc. As the 21st century green transportation, electric vehicles are generally valued in various countries. Electric vehicle -driven motors are mainly high -power permanent magnetic brushless DC motors, permanent magnet synchronous motors, switching magnetic resistance motors, etc. High efficiency, high force, intelligence. Domestic electric bicycles have developed rapidly in recent years. Electric bicycles mainly use line -winding permanent magnet DC motors and permanent magnetic brushless DC motors. In addition, special motors have also been widely used in locomotive drivers and ship promotion, such as the linear motor, such as the linear motor. Driven for magnetic suspension trains and subway trains.
    The field of home appliances, about 50 to 100 special motors in industrialized countries, the main varieties of motor are: permanent magnet DC motors, single -phase induction motors, string motors, step motor, brushless DC electric motors , AC servo motor. In order to meet the needs of users’ increasingly higher requirements and the needs of the development of the information age, the energy saving of household appliances products, the comfort, network, and intelligent of the employment platform for the motor industry, the update cycle of household appliances is fast, and the supporting motor The requirements for high efficiency, low noise, low vibration, low price, speed adjustment and intelligence are required. The use of motors in the household appliance industry is being updated. Household electrical appliances driven by high -efficiency permanent brushless DC electric motors are representing the direction of the development of the home appliance industry. If the current high -efficiency energy -saving inverter air conditioner and refrigerator are used to drive the compressor and fan with permanent magnetic brushless DC motor. The washing machine uses a low -noise multi -polar flat permanent brushless DC motor, which can save the original mechanical reducer and directly drive the roller to achieve a levelless speed regulation. It is currently a high -end product in the washing machine. The vacuum cleaner uses a permanent brushless DC motor to replace the original single -phase string motor, which has the advantages of small volume, high efficiency, low noise, long life and other advantages.
    The audio and video equipment such as electric voices in the consumer electronics field, recorder, VCD vision disk, and DVD vision disk, as well as high -end smart toys and entertainment and fitness equipment supporting motors are mainly permanent magnet DC motors, printed winding motors, line winding motors, brush -free DC DC Electric motor, etc. Video machines, cameras, digital cameras and other electronic consumer products require large amount, product updates are fast. The distribution of such products is precise, and it is difficult to manufacture and processing. Especially after digitalization, the motor has been updated and higher. Essence
    The military special motor and component products in the national defense field have many categories and different specifications. There are nearly 10,000 varieties. The basic functions are: mechanical location sensing and instructions, signal transformation and calculation, motion speed detection and feedback, sports device, sports device Drive and positioning, speed, acceleration, position accurate servo control, timing standards and small power power supply. Based on the requirements of its special performance, special functions, and special working environment, a large number of technical achievements of related disciplines, especially the application of new technologies, new materials and new processes, have spawned many new structures and new principles motors, with distinctive micro -miniature. The characteristics of digitalization, digitalization, multifunctional, intelligent, systematic and network. For example, the traditional torpedo steering gear uses the hydraulic mechanical driving system to drive the rudder surface, providing three -axis power for torpedo to control the direction, depth and rolling rolls to achieve the designed torpedo ballistic. At present Most of the electric motor uses a DC servo motor, but the inherent shortcomings of brush servo motors have brought many problems to the reliable operation of the motor system. The rare earth permanent magnetic brushless DC electric motors with small size, high quality, high power density, high power indicators, and good servo performance and dynamic characteristics meet the special requirements of the torpedo electric steering gear system. At present, special motors that are key applications and development in the national defense field are permanent magnet AC servo systems; permanent magnetic brushless DC motors; high -frequency and high -precision dual -channel rotation transformers; micro, light, thin -permanent magnetic rotomostic motors; high -precision angle sensing sensing Electric; step motor and driver; low inertia DC servo motor; permanent magnet rigid torque speed measurement; driver motor adding speeder components; ultrasonic motors; straight lines and direct drive motors.
    The various aircraft, detectors, automated equipment, medical equipment, etc. used in special fields of special fields are special motors or new motors, including in principle, structure and operation. The motor of the general electromagnetic principle is mainly low -speed synchronous motors, harmonic motors, limited corner motors, ultrasonic motors, microwave motors, capacitive motors, static electric motors, etc. For example, an ultrasonic motor with a thickness of 0.4 mm is applied to a miniature helicopter; the micro ultrasonic motor is applied to the mobile phone system of the mobile phone.

  2. The asynchronous motor is an AC motor. The speed of the speed during the load is not a constant relationship with the frequency of the power grid. It also changes with the size of the load. The larger the load torque, the lower the rotor speed. The asynchronous motor includes inductive motors, dual -feeding asynchronous motors, and AC -directional motors. The inductive motor is the most widely used. Without misunderstanding or confusion, the inductive motor is generally the asynchronous motor.
    The stator winding of the ordinary asynchronous motor is connected to the communication grid. The rotor winding does not need to be connected to other power supply. Therefore, it has the advantages of simple structure, convenient manufacturing, use and maintenance, reliable operation and small quality, low cost and so on. The asynchronous motor has high operating efficiency and good working characteristics. It is close to the constant speed operation from the air load to the full load range, which can meet the transmission requirements of most industrial and agricultural production machinery. The asynchronous motor is also convenient to form various protective types to meet the needs of different environmental conditions. When running an asynchronous motor, it is necessary to absorb the power -free motivation power from the grid to make the power factor of the power grid bad.
    Therefore, a synchronous motor is often used for high -power and low -speed mechanical equipment such as driving ball mills and compressors. Because the speed of the asynchronous motor has a certain rotation relationship with its rotating magnetic field speed, its speed regulation performance is poor (except for AC -turnable motors). For transportation machinery, rolling machines, large machine tools, printing dyeing and papermaking machinery, which requires a wide range of wide and smooth speed adjustment range, the DC motor is more economical and convenient. However, with the development of high -power electronic devices and AC speed regulation systems, the speed regulation performance and economy of asynchronous motor suitable for wide -speed speed can be comparable to DC motors.
    A asynchronous motor is mainly used as an electric motor. Its power range is from several watts to tens of thousands of kilowatts. It is the most widely used motor in various industries of the national economy and people in daily life, providing motivation for a variety of mechanical equipment and household appliances. For example, machine tools, small and medium -sized steel rolling equipment, fans, pumps, light industrial machinery, metallurgy and mining machinery, etc., mostly use three -phase asynchronous motor () dragging; electric fan, washing machine, refrigerator, air conditioner and other household appliances are widely used Single -phase asynchronous motor. Asynchronous motors can also be used as generators for wind power plants and small hydropower stations.
