Domestic stepper motor selection 15, domestic stepper motor selection

Advantages of servo motor: 1. Accuracy: Closed-loop control of position, speed and torque is realized; Overcome the problem of stepper motor out-of-step; 2. Speed:

Good high-speed performance, the general rated speed can reach 2 3 rpm; 3. Adaptability: strong anti-overload ability, can withstand three times the load of rated torque, and is especially suitable for occasions with instantaneous load fluctuations and requirements for fast starting; 4. Stable: Stable operation at low speed, and no stepping operation phenomenon similar to that of stepper motor will occur during low speed operation.

It is suitable for occasions with high-speed response requirements; 5. Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds; 6. Comfort: Heat and noise are significantly reduced.

Disadvantages of servo motors: Servo motors can be used in places where they can be attacked by water or oil droplets, but they are not completely waterproof or oil-proof. Hence ,...

After nearly 100 years of development, a large number of brands have emerged around the world, each with its own strengths. Today, I will take you to analyze the advantages and disadvantages of each brand in China's industrial market one by one.

Imported brands. Japan.

1. Oriental Motor (founded in Japan in 1885), the longest history, the most abundant products, the most expensive.

2. Shinano Motor (founded in Japan in 1918), survives in the form of a factory, with the advantage of domestic factories and the cost advantage of mass production.

Europe. 1. Italy Aiwei (founded in 1977), there is a production plant in Changzhou, China, the bus (Ethercat, Profinet) control technology is the most stable, and some products are UL certified.

2. Nanotec (founded in 1991), there is a production plant in Changzhou, China, all kinds of non-standard customization, the all-in-one machine is relatively stable, and some products are UL certified.

Korea. 1. Fastech, which was not bad in the domestic market earlier, is mainly based on closed-loop and bus. In recent years, the main focus has been on overseas markets, and the domestic market share is not as good as before.

Domestic brand. 1. Ming Zhi, the acquisition of American technology, in the domestic brand, the technology is leading, but the market promotion is average.

2. Leisai, an earlier brand in China, promoted earlier, has a high market share, and its products are different. The technical aspect is to follow.

3. Research and control, little Leisai, what Leisai does and what he does.

Other brands. There are no less than 100 other brands in China, which basically rely on their relationships to do some customers. These brands basically have no R&D strength, or their R&D strength is limited to a small area.

Mainly in the first situation, what customers need, what they look for in the market. It is not uncommon for different brands to give the same product to customers.

There are many domestic brands of micro stepper motors:

Zhengde (Maintex), Wanzhida, Weizhen, and Keshuo have all done well.

R&C, Leisai, Jiemeikang and so on.

Imports, Oriental. Domestic, Mingzhi, Shanghai Vertical Ming, Lei Sai.

There are many domestic stepper motor brands, and there doesn't seem to be a well-known brand. Both can be used, and there is not much difference.

Shenzhen Ruite's stepper motor is good, cost-effective than Leisai, and the stability is also strong, and it has been used.

Shenzhen Best Automation Technology Co., Ltd. is a company through independent research and development and the introduction of mature technology at home and abroad, has successfully developed and mass-produced a variety of cost-effective high-quality motion control products, including stepper motors, stepper drivers, gear reduction stepper motors, planetary stepper motors, brake stepper motors and supporting drives. The company takes intelligent control technology as the core, introduces foreign advanced technology, and has more stable quality and more cost-effective compared with peer products! Brand OEM!

The stepper motor brand Handbao is OEM produced in the Bebaite manufacturer!

If the first-line domestic big brand is Leisai, Mingzhi... But it's not a good deal if it's not a lot of money. To quality and cost-effective, you can consider Hongchuangxing, are the same batch of engineers, although the brand is not loud, but do fine, quality service is good.

Imported brands.

1. Japan Oriental, the longest history, the most abundant products, of course, the most expensive **2, Italy Aiweiever, the earliest manufacturer of bus stepper motor drivers (PROFINET, ETHERCAT).

3. South Korea's fastech, a domestic brand of manufacturers with better closed-loop algorithms:

1. Leisai, the earliest in China, has a large market share, and the products are said to be Fengyun 2, Mingzhi, half of the foreign technology, the domestic technology is leading, and the market share is generally OEM-based other brands, and there is no independent research and development production capacity.

The better brands of stepper motors are ABB, Siemens, Siemens, Dayang Motor, Johnson, and Delta Delta.

The selection of stepper motor can be based on these aspects: the selection of stepper motor torque, the selection of stepper motor speed, the selection of the use environment of the stepper motor, the selection of the phase number of the stepper motor, and whether special specifications can be required according to your actual situation

1. Selection of stepper motor torque: the holding torque of stepper motor is similar to the "power" called by traditional motors. Of course, there are essential differences.

The physical structure of a stepper motor is completely different from that of AC and DC motors, and the output power of the motor is variable. Usually, according to the size of the torque (i.e., the amount of torque to be driven), which type of motor is selected.

Roughly speaking, the torque is as follows, select (the diameter or square of the motor body, unit: mm); If the torque is on the left and right, it is more appropriate to choose the 57 motor. In the case of several or greater torques, it is necessary to choose a stepper motor of the same specification.

2. Selection of stepping motor speed: special consideration should be given to the speed of the motor. Because the output torque of the motor is inversely proportional to the speed.

That is to say, the torque of the stepper motor is very small at low speed (hundreds of revolutions per minute or lower), and the torque at high speed (1000 rpm - 9000 rpm) is very small. Of course, some working conditions require high-speed motors, and the coil resistance, inductance and other indicators of the stepper motor must be measured. Choose a motor with a slightly smaller inductance as a high-speed motor to obtain a large output torque.

On the contrary, in the case of low-speed high torque, it is better to choose an inductance in more than ten or tens of MH, and the resistance should be larger.

3. Choose according to the environment in which the stepper motor is used: the special stepper motor can be waterproof and oil-proof, and is used in some special occasions. Underwater robots, for example, need a water discharge motor. For special-purpose motors, it is necessary to select them in a targeted manner.

4. The phase number selection of the stepper motor: the phase number selection of the stepper motor, many customers pay little attention to this content, and most of them buy it casually. In fact, the working effect of motors with different phases is different.

The more phases there are, the smaller the step angle can be, and the smaller the vibration when working. In most cases, two-phase motors are used. In the working environment of high speed and high torque, it is more practical to choose a three-phase stepper motor.

5. According to your actual situation, whether you need special specifications: special specifications of stepper motors, please communicate with us, within the scope of technical permission, processing and ordering. For example, the diameter, length, and direction of the outgoing shaft.
