What is the difference between DC motor and gear motor?
2023 / 10 / 21
DC motors and gear motors are two different motor types with the following differences: 1. Different structures: A DC motor is a motor that converts DC electrical energy into mechanical energy. It usually consists of an armature, a permanent magnet and a commutator. A gear motor is an electric motor that converts electrical energy into mechanical energy. It usually consists of an electric motor and one or more gears. 2. Different working principles: DC motors generate magnetic fields between the armature and permanent magnets through current, thereby generating electromagnetic force and torque to achieve rotation. Gear motors work similarly to DC motors, generating torque through the interaction between the armature and the magnetic field. 3. Different application scenarios: DC motors are widely used in household appliances, industrial equipment, automobiles, ships and other fields. Especially suitable for occasions where precise control of speed and torque is required. Gear motors are usually used in applications that require high torque output and low speed drive, such as industrial machinery, robotic arms, automatic doors, etc. 4. Different characteristics: DC motor: (1) Wide speed adjustment range: DC motor has a wide speed adjustment range and can be adjusted by changin

We know that the small DC motor operates according to the mechanical kinetic energy caused by electromagnetic energy (mentioned in the previous article), but this kind of operation can only rotate the whole process and can not cause vibration. At this time, we must assemble a rack on the shaft of the small motor. When the small motor is running, the simple harmonic motion of the center point of the rack has no rotating center of the motor, so the small motor will keep in an unbalanced situation, and the vibration is formed by the effect of inertial force. The higher the speed ratio, the greater the vibration frequency.

Many manufacturers are concerned about the basic principle of the reduction motor, but they can't understand the professional data. Today, Shunchang motor, a Shenzhen reduction motor manufacturer, will reveal the basic principle of the reduction motor for you. Do you want to know what it is? Let's have a look with Shunchang motor Xiaobian! Basic principle of reduction motor The brief discussion is to reduce the speed ratio, expand the torque and reduce the inertia Shenzhen reducer motor manufacturer The gear reducer uses each transmission gear to achieve the purpose of deceleration. The reducer is composed of each transmission gear pair. For example, pushing the transmission wheel with the transmission gear can achieve a certain purpose of deceleration, and then selecting a multi-level structure can greatly reduce the speed ratio. The gear reducer is generally used for motor equipment with low speed ratio and high torque, According to the driving force of motor, gas turbine or other high-speed operation, the gear with less teeth on the input shaft of the reducer is meshed with the transmission wheel on the output shaft to achieve the purpose of deceleration. In general, there will be several groups of transmission gears with the same basic principle to achieve the ideal actual effect of deceleration. The ratio of the number of teeth of the size transmission gear is the reduction ratio.

2021 / 06 / 25
With the development of society, the application of DC motor is more and more common, and the requirement of DC motor control mode is also increasing. In this paper, the design of DC motor function module based on NiosII soft core processor is proposed by using SOPC solution newly developed by Altera company, and the IP core of VHDL code generation function module is given. The generation of IP core is not only convenient for designers to use flexibly, save resources, but also greatly shorten the design cycle. Designers can call IP core directly to form NiosII system, and then download the system to FPGA. IP core not only can be used in motor control, but also can be used to control some other small appliances, full-color LED, etc. Overall hardware design of DC motor As shown in Figure 1, the whole system is controlled by FPGA chip, and its control core is NiosII soft core CPU of Altera company. This paper focuses on the design and generation of two control function modules, PWM module and speed measurement module. The two control function modules are designed and generated by VHDL hardware description language, which can be called IP core. They are compiled and simulated by QuartusII to verify their correctness. Finally, the generated user-defined interface function module is added to the top-level schematic diagram to complete the design of the whole speed regulation system.

Since the opening of the Olympic Games in London, the hearts of hundreds of millions of Chinese people have been concerned. With the news of success on the field, the mood of the audience is getting higher and higher. The sponsors of the London Olympic Games have spent a lot of money on publicity and marketing, and many other enterprises are not willing to let go of this rare marketing opportunity. Although they do not have the publicity strength of the sponsors, they also try their best to attract attention through various channels and taking advantage of the east wind of the Olympic Games www.sc-motor.cn/ . (micromotor) Xiaobian observed that before and after the Olympic Games, many domestic enterprises and manufacturers planned various promotional and promotional activities in the name of the Olympic Games. This includes a large number of furniture hardware, ceramic bathroom, electronics and electrical hardware and electrical (micro motor) related industries. These enterprises either reduce prices and promote sales through physical stores and online shopping malls, or launch award-winning activities related to the Olympic Games through microblogs, forums and other network information exchange platforms, so as to strengthen interaction with consumers and expand brand awareness and influence. In the highly competitive market environment, it's not unreasonable to carry out marketing with the help of social hot spots combined with their own, but too many enterprises carry out similar marketing activities at the same time, which is lack of innovation, not only makes consumers feel numb, but also makes enterprise marketing encounter a bottleneck. In addition, the marketing activities carried out by some enterprises in order to attract attention can cause a lot of attention in a short period of time, but because they cheat consumers and violate public values, they do great harm to the brand image of enterprises. www.sc-motor.cn/

According to the report, "last year, the production growth rate of the whole heavy machinery industry dropped sharply, returning from high speed to medium speed growth area, and continued to decline. During this period, our enterprises still need to seize the time to lay a good foundation and practice their internal skills. Only when the market is good can we seize the opportunity. " Recently, Li Jing, executive vice president of China Heavy Machinery Industry Association, said at the second session of the sixth member congress and Council of China Heavy Machinery Industry Association. The relevant person in charge of the Association believes that in general, 2013 will be a more severe year for the heavy machinery industry. According to the order situation of some key enterprises, only a few enterprises can meet the annual order, and the varieties are not balanced, and some order contracts are not safe. The difficulties in production and operation of the whole industry have increased, and the possibility of further decline in the first half of the year cannot be ruled out. Even if the macro-economy has picked up, according to the rule that the heavy machinery (reducer motor) industry is later than other leading industries, it will not change until later. It is expected that metallurgical machinery will continue to decline and may have negative growth; The growth rate of mining machinery was the same as that of the previous year, and the material handling machinery increased in the middle and later period of the year. The annual growth rate is about 10% ~ 12%, lower than that of 2012. Affected by uncontrollable factors such as labor, energy, capital turnover, contract withdrawal and extension, the efficiency continued to decline. There is still room for export, which can maintain a small growth trend (reduction motor). Since last year, the development status of heavy-duty (reduction motor) machinery has attracted the attention of the old leaders and com
Application advantages of various DC motors in industrial robots
2021 / 04 / 20
The motor (DC motor, micro motor, deceleration motor) is used to drive the joints of robot, which requires maximum power mass ratio, torque inertia ratio, high starting torque, low inertia and wide and smooth speed range. Especially for the robot end effector (gripper), the motor (DC motor, micro motor, deceleration motor) with the smallest volume and mass should be used, especially when the rapid response is required, the servo motor must have high reliability and large short-time overload capacity. Specific requirements: Rapidity (DC motor, micro motor, reduction motor). The starting torque inertia ratio is large. The continuity and linearity of the control characteristics, with the change of the control signal, the speed of the motor can change continuously, and sometimes it needs to be proportional or approximately proportional to the control signal. Wide speed range. Small volume, small mass and short axial dimension. It can withstand the harsh operation conditions, can carry out very frequent forward and reverse and acceleration and deceleration operation, and can withstand overload in a short time. At present, AC and DC servo motors with high starting torque, large torque and low inertia are widely used in industrial robots. Other motors, such as AC servo motor, DC motor, deceleration motor and stepping motor, will also be applied to industrial robots according to different application requirements.
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
