How do motor manufacturers improve motor efficiency?
With the development of the industrial manufacturing industry, electric motors are widely used in people’s production and manufacturing. According to data analysis, the electric energy used by the motor operation can account for 80% of the entire industrial electricity consumption. Therefor...Read more -
Principle of asynchronous motor
Application of Asynchronous Motor Asynchronous motors that operate as electric motors. Because the rotor winding current is induced, it is also called an induction motor. Asynchronous motors are the most widely used and the most demanded of all types of motors. About 90% of the machines po...Read more -
Development history of induction motor control technology
The history of electric motors dates back to 1820, when Hans Christian Oster discovered the magnetic effect of electric current, and a year later Michael Faraday discovered electromagnetic rotation and built the first primitive DC motor. Faraday discovered electromagnetic induction in 1831, but i...Read more -
Why can the motors of fans and refrigerators keep running, but not the meat grinder?
After entering deep summer, my mother said that she wanted to eat dumplings. Based on the principle of the genuine dumplings made by myself, I went out and weighed 2 pounds of meat to prepare dumplings by myself. Worrying that the mincing will disturb the people, I took out the meat grinder that ...Read more -
What are the advantages of electric heating dip varnish?
Compared with other insulation treatment processes, what are the advantages of electric heating dip varnish? With the development of motor manufacturing technology, the winding insulation process has been continuously changed and upgraded. VPI vacuum pressure dipping equipment has become t...Read more -
How does the motor manufacturing industry choose qualified suppliers?
Quality is often touted and often referred to as a cliché, and even when it’s used as a buzzword, many engineers throw the idea out of the way before delving into the situation. Every company wants to use this word, but how many are willing to use it? Quality is an attitude and a way of lif...Read more -
Which motors use rain caps?
The protection level is an important performance parameter of motor products, and it is the protection requirement for the motor housing. It is characterized by the letter “IP” plus numbers. IP23, 1P44, IP54, IP55 and IP56 are the more commonly used protection levels for motor product...Read more -
Three Ways to Reduce Motor Weight and Improve Efficiency
Depending on the type of system being designed and the underlying environment in which it operates, motor weight can be very important to the overall cost and operating value of the system. Motor weight reduction can be addressed in several directions, including universal motor design, efficient ...Read more -
The efficiency of the motor cannot be evaluated only by the magnitude of the current
For motor products, power and efficiency are very critical performance indicators. Professional motor manufacturers and test institutions will conduct tests and evaluations in accordance with corresponding standards; and for motor users, they often use current to evaluate intuitively. As a result...Read more -
Permanent magnet motor saves 5 million yuan a year? It’s time to witness the “miracle”!
Relying on the Suzhou Metro Line 3 project, a new generation of permanent magnet synchronous traction system developed by Huichuan Jingwei Railway has been operating in Suzhou Rail Transit Line 3 0345 vehicles for more than 90,000 kilometers. After more than a year of energy-saving verification t...Read more -
