The development of micromotor to high speed is expected to become a new economic growth point
2021 / 04 / 09
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

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

When people are concerned about how chang'e-3 is successfully launched on the long march 3B carrier rocket, they should also pay attention to the micro motor on the lander, which plays a vital role. Under the embargo of rocket components imposed on China by developed countries for many years, chang'e-3 can finally embark on the journey to the moon, which also witnesses the outstanding spirit of independent innovation of mainland scientists under difficult conditions . Xiong Qunli, deputy commander in chief of the lunar exploration project and general manager of China Electronics Technology Group, for example, said that because there was no atmosphere on the moon, chang'e-3 could not land by parachute, and could only rely on the 7500 Niu variable thrust engine on the lander to complete a series of actions such as deceleration and hovering. The choice of thrust is realized by a small cylindrical motor (Shunchang motor company specializes in making all kinds of DC motors with outer diameter of 12-37mm). Xiong Qunli said that there are more than 30 kinds of motors on the chang'e-3 probe (the steering motor is commonly used on model aircraft with high speed and large torque), which are distributed in the antenna, battery array, imaging system, mast system, mechanical arm system, detection and sampling system and other subsystems. Every link should not be wrong, otherwise, it will be directly related to the lunar exploration mission Whether it can be a complete success. "If it wasn't for the developed countries' embargo on many components, China could import the whole set of measurement and control system. Including some important parts and components of the chang'e-3 TT & C system In the view of Shi Jinhao, an expert in China's electronic components, the motor components of European and American countries in the field of weapons and aerospace have been closed to China. "Especially in space exploration, the motor of antenna deployment is forbidden."
Active listening - restart employee power motor (micro motor)
2021 / 04 / 03
Since entering 2012, due to the influence of the overall economic situation in China, the performance of many micro motor companies has declined a lot. Some management problems of micro motor companies that were ignored and covered up in the rapid growth began to emerge. Measures such as salary reduction, layoffs and department integration led to low morale and managers' anxiety. Eric, the sales director of micromotor, has been a tough day recently, saying, in his own words, "the feeling is going to be overwhelmed.". Originally, due to the decline in sales performance, the company hopes to reduce losses and overcome difficulties through production control and department integration. As the key department of this adjustment, although Eric has stated the importance and necessity of the current move several times within the Department, when a series of measures such as reducing employees, reducing salary slightly and adjusting posts are implemented, the subordinates still show great dissatisfaction. After the shock, the problem soon exposed: the atmosphere of the Department began to become a little impetuous, a large number of employees' negative and slack mood gradually increased, and the work efficiency also decreased a lot. Eric even heard the "gossip" that some backbone sales plan to leave. What should I do? This is not a big problem for Eric, who has always been democratic and active in management, because he has been actively asked by subordinates to talk to him soon. But facing the complaints and complaints that subordinates show in the conversation, Eric, who is in a hurry, is hard to sit down. He always breaks down on his subordinates' words and starts to give advice and suggestions "with reason and emotion". Eric didn't expect that after a hard work, it seemed that his subordinates didn't seem to pay much, and their work efficiency was never raised. Eric, tired of coping, began to feel anxious. Yes, how can their subordinates' comp
China's robot industry has a huge market development space
2021 / 04 / 01
There is still a large development space for China's robot industry, which is mainly based on the following considerations: the scale of machine tool industry indicates that the manufacturing industry in China has a huge demand for automatic processing equipment; (Shunchang motor specializes in manufacturing robot micro motor). The density of robot use in China is very low, and the improvement of robot usage density will promote the demand of robots. By comparing virtue Japan and Korea, we estimate that the market size of robots in China will exceed 1.6 million, which has a huge development space compared with the assembly capacity of less than 100000 units at present. China Construction Investment believes that with abundant supply of engineers and "engineer bonus" of lower engineer price, Chinese robot enterprises are expected to improve their global competitiveness and the market has a good development opportunity. Compared with developed countries, the density of manufacturing robots in China (that is, the number of industrial robots installed per 10000 workers) (Shunchang motor is also very specialized in manufacturing micro reduction motor of robots). Only 21, which can not only be compared with developed countries, but also lower than the average level of 55 in the world, and there will be a significant improvement in the future. At the end of 2011, there were 40.88 million workers in China's manufacturing industry. Assuming that the density of industrial robots in China's manufacturing industry is equivalent to the average level of 55 in the world, 225000 industrial robots are required. At present, China has 74000 robots, and then 151000 industrial robots will be added. At present, Shenyang Xinsong robot, Anhui evte and Guangzhou CNC are the first echelons of domestic robot production enterprises, among which Shenyang Xinsong has the background of Shenyang Automation Institute of Chinese Academy of Sciences, and the R & D ability is in

1. The basic construction of DC motor The basic structure of DC motor is the same as that of AC motor, it is also composed of motor stator and motor rotor. Figure 1 shows the construction of a DC motor. Figure 1 DC motor construction 1-cooling fan; 2-motor shaft; 3-armature; 4-main magnetic pole; 5-motor carbon brush; 6-motor rotor; 7-patch plate 8-group outlet box; 9-bearing end cover 1. motor stator The key of the stator of DC motor is composed of main pole, commutation pole, brush equipment, motor shaft and bearing end cover. 1) Main pole The main magnetic pole is used to cause the main electromagnetic field in the DC motor operation. It is composed of two parts: the core and the excitation winding which is sheathed on the core, as shown in Figure 2. The core part of the winding lock sleeve is called the pole body, and the wider part near the armature (motor rotor) is called the pole shoe. Most of the main poles of DC motors do not need electromagnets, but the excitation winding creates electromagnetic fields according to DC power supply. If the direction of excitation current is changed, the direction of main magnetic field will also be changed. The pole shoe can fix the real excitation winding, and can also be of the magnetoelectric type with smaller magnetic density, and make the electromagnetic field more symmetrical and effective in the magnetic density. Although the electromagnetic field caused by DC power does not cause the loss, the electromagnetic field on the surface of the pole changes during the armature fitness, so eddy current loss is needed on the core. In order to reduce the iron loss better, the main pole core is made of 1-1.5mm thick low magnetic thick steel plate stamping die. The key to the iron chip is air oxide film insulation. The excitation winding is made of the inductor of the copper core coil of the insulation layer. It is divided in

After motor gear motor (dc motor) be affected with damp be affected with damp
2019 / 10 / 21
There are a lot of enterprises in the actual production, often find some motor placed unused for a period of time, when enabled again found motor (dc motor slowdown motor winding insulation resistance is reduced, especially in the rainy season, the air humidity is big, its insulation value decreases to zero, even at this time should be dry processing, so that the insulation resistance, absorption ratio specified value, if the first put into operation, it is possible to make the motor gear motor (dc motor) coil insulation breakdown, cause an accident. External heat source heating method, the best is a dedicated motor drying oven to dry, this method is convenient, safe and reliable operation. Another to be affected with damp be affected with damp to overhaul its electric motor, using high-power incandescent bulbs into the motor internal bake, but applies only to easy to overhaul the small motor (dc motor slowdown). For large and medium-sized or difficult to overhaul the motor workload is relatively large, but also reduces the feasibility. Operation should pay attention to is: this method when the light bulb or heat source is too close to the coil, in case of burn out the coil can be on the motor gear motor (dc motor) housing the canvas items such as thermal insulation.
