• Analysis of the difficulties of low efficiency encountered by the motor (DC motor) in China

  2021 / 04 / 11

  The lack of initiative by Chinese users is largely due to the high cost of high-efficiency motors (DC motors), which are almost no longer present in the United States. The test standards issued by IEC (hereinafter referred to as IEC) of the International Electrotechnical Commission make it possible to evaluate the energy efficiency of motors. In recent 10 years, the motor market has developed rapidly, the international motor (DC motor) production level has been improving, and the evaluation standards for technical development have been improving in recent years. Nowadays, the high efficiency motor is no longer the same level of the year. The latest classification standard regards IE1 as general energy efficiency, IE2 is the first-class energy efficiency, while ie3 is the most energy-saving and the highest energy efficiency. Such a standard division improves the overall energy efficiency level of the motor by one level. [IEC+MEPS" As early as 10 years ago, the energy efficiency evaluation standard for motor (DC motor) has been put forward. There was still a big debate between the United States and Europe about this issue at that time, because they couldn't agree on the energy efficiency of the motor. And over the past five years, things have changed. The earliest international standards were issued by IEC. IE1, IE2 and ie3 were classified as the international motor (DC motor) energy efficiency assessment. However, the development of each country is different, and there are some inevitable problems in the evaluation of unified standards. Conrad u.bruner, chairman of the top ten energy conservation center of the international energy efficiency organization, told China economy and information technology that, in addition to IEC standards, each country is developing its own mandatory energy efficiency standards, which is called "MEPs". "MEPs" is the minimum energy performance standards. In the past five years, many countri

• The development of micromotor to high speed is expected to become a new economic growth point

  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 researchin

• Domestic micro motor makes "Chang'e girl" nerve sensitive

  2021 / 04 / 07

  In the morning in phoenix net to see an article is really good! Reprint it to show you! --Shunchang motor, professional production of micro motor, DC motor, reducer motor, all kinds of micro brush permanent magnet motor. Chang'e-3 flew into the sky early in the morning of February 2 and is expected to make a soft landing in the moon's Rainbow Bay Area in the middle of this month. The setting of the moon should be accurate and stable, the "nerve fiber" of the detector must be smart, and the "joint" must be sensitive. "Chang'e's flight to the moon is very different from the return of manned space flight. The moon landing mission is carried out in an airless environment, not by parachute, but by thruster. We have participated in the development of sensors and many special motors for reverse thrust engines. This is exactly where developed countries have blocked our technology. " Xiong Qunli, deputy commander in chief of lunar exploration project and general manager of China Electronics Technology Group, said. The motor enables the moving parts in engineering to accurately execute the command and control of the brain. According to the introduction, more than 30 kinds of chang'e-3 detector motors are distributed in the antenna, battery array, imaging system, mast system, mechanical arm system, detection sampling system and other subsystems. After several flight verifications, they have reached the aerospace requirements of high level and reliable operation, reflecting the strength of domestic motor (Shunchang motor, a domestic professional micro motor manufacturing company). "Three girls" lunar soft landing, relying on 7500 cattle variable thrust engine to complete deceleration, hovering and a series of actions. The choice of thrust is realized by a small cylindrical motor. Li Tingbin, an engineer of CETC, said that the principle of the motor is like the accelerator of a car, which controls the opening and closing of the valve through di
