Motor production, electromagnetic wire, bearing, insulation and other materials motor manufacturers will have strict standard control, such as Senli motor used enameled wire material for 180° high temperature resistant material, improve quality to ensure stable motor operation; When painting the stator, insulating paint is also one of the most important raw materials in the production and manufacturing process. Today, Senli Motor small series simply tells about the detection of insulating paint for motor winding.

Three-phase asynchronous motor installation methods are diverse, such as Senli motor B3 horizontal installation, B34 vertical horizontal installation, B5 vertical large flange installation and B14 vertical small flange installation, which vertical and horizontal asynchronous motor the biggest difference is the installation method, followed by different structural design, below and Senli motor Xiaobian together to understand it.

According to its material characteristics, the rotor can be divided into wound rotor, cast aluminum rotor, permanent magnet rotor, and the application of cast aluminum rotor is the most widely used one, mainly from the technological advantages of this type of rotor, the following torque motor manufacturers will take you to briefly understand the cast aluminum rotor.

The additional resistance is inserted into the rotor of the winding asynchronous motor, which increases the slip rate of the motor and makes the motor run at a lower speed. The greater the resistance in the series, the lower the speed of the motor. This method has simple equipment and convenient control, but the slip power is consumed on the resistor in the form of heat, it is a step speed regulation, and the mechanical characteristics are soft.

If you change the stator voltage of the asynchronous motor, you can get a different set of mechanical characteristics curve, then the obtained speed will be different, three-phase asynchronous motor can be adjusted by the method of stator pressure regulation, below and Senli motor Xiaobian together with a simple understanding of it.

In front of the front talked about a lot of asynchronous motor speed regulation, today we simply talk about the electromagnetic speed regulation motor speed regulation, the general electromagnetic speed regulation motor by the cage asynchronous motor, electromagnetic slip clutch and DC excitation power supply (controller) three parts.

In the daily machinery production industry, speed regulation is also widely used; The speed regulation we commonly use is to change the motor speed by changing the number of magnetic poles, current, voltage, frequency and other ways, so that the three-phase asynchronous motor and other products to achieve a higher performance, and then the Senli motor editor will briefly introduce the speed regulation method about changing the number of poles.

According to the speed formula n=60f/p, in addition to changing the number of poles, it can also be achieved by changing the frequency f. Frequency conversion speed regulation is to change the speed regulation mode by changing the stator power supply frequency of the three-phase asynchronous motor, of course, the main equipment of frequency conversion speed regulation is to provide frequency conversion power to achieve.

Cascade speed regulation refers to the speed regulation formed by the two-stage connection of DC motors attached outside the rotor, although it was later improved to replace DC motors with static power electronic converter devices and transformers, but the term cascade speed regulation is used. The cascade speed regulation of three-phase asynchronous motor is to change the motor slip by adding adjustable additional potential into the rotor loop of winding motor to achieve the purpose of speed regulation.

Frequency conversion motor frequency is adjustable design, so motor manufacturers can produce a lot of high-speed motors, in high-speed operation can maintain the characteristics of constant torque, to some extent instead of the original medium frequency motor, the following Senforce motor Xiaobian will take you to understand, about the selection of frequency conversion motor.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
