High power synchronous motor emergency braking technology
0 1 Overview After cutting off the power supply, the motor still needs to rotate for a period of time before it stops due to its own inertia. In actual working conditions, some loads require the motor to stop quickly, which requires braking control of the motor. The so-called br...Read more -
[Knowledge Sharing] Why do DC permanent magnet motor poles mostly use rectangular magnets?
The permanent magnet auxiliary exciter is a new type of external rotor DC permanent magnet motor. Its rotating choke ring is directly suspended deep in the shaft. There are 20 magnetic poles on the ring. Each pole has an integral pole shoe. The pole body is composed of three rectangular pieces. I...Read more -
In 2024, three things to look forward to in the motor industry
Editor’s note: Motor products are the core elements of the modern industrial revolution, and industrial chains and industry groups with motor products or the motor industry as the divergence point have quietly emerged; chain extension, chain expansion and chain complementation have grad...Read more -
How is the back electromotive force of the permanent magnet synchronous motor generated? Why is it called back electromotive force?
1. How is back electromotive force generated? In fact, the generation of back electromotive force is easy to understand. Students with better memory should know that they have been exposed to it as early as junior high school and high school. However, it was called induced electromotive force ...Read more -

[Technical Guidance] What is a brushless motor driver and what are its characteristics?
The brushless motor driver is also called a brushless ESC, and its full name is a brushless electronic speed regulator. The brushless DC motor is a closed-loop control. At the same time, the system features an input power supply of AC180/250VAC 50/60Hz, and a wall-mounted box structure. Next, I w...Read more -
How the noise of brushless motors is generated
Brushless motors produce noise: The first situation may be the commutation angle of the brushless motor itself. You should carefully check the commutation program of the motor. If the motor commutation angle is incorrect, it will also cause noise; The second situation may be that the elec...Read more -
[Key Analysis] For this type of air compressor, two types of motors must be distinguished
The motor is the key power device of the screw air compressor, and it plays a major role in the components of the air compressor. Everyone knows that air compressors are divided into ordinary power frequency and permanent magnet variable frequency, so is there any difference between the two motor...Read more -
How do motor materials match insulation levels?
Due to the particularity of the motor’s operating environment and working conditions, the insulation level of the winding is very important. For example, motors with different insulation levels use electromagnetic wires, insulating materials, lead wires, fans, bearings, grease and other mat...Read more -
An old electrician will tell you the reason for motor stalling and burning. This can be prevented by doing this.
If the motor is blocked for a long time, it will burn out. This is a problem often encountered in the production process, especially for motors controlled by AC contactors. I saw someone on the Internet analyzing the reason, which is that after the rotor is blocked, the electrical energy cannot ...Read more -
The relationship between no-load current, loss and temperature rise of three-phase asynchronous motor
0.Introduction The no-load current and loss of a cage-type three-phase asynchronous motor are important parameters that reflect the efficiency and electrical performance of the motor. They are data indicators that can be directly measured at the use site after the motor is manufactured and repair...Read more -
What is the most serious failure of high-voltage motors?
There are many reasons for the failure of AC high-voltage motors. For this reason, it is necessary to explore a set of targeted and clear troubleshooting methods for various types of failures, and propose effective preventive measures to eliminate failures in high-voltage motors in a timely ma...Read more
