The working principle of the electric motor and the principle of the generator!
01 Electric current, magnetic field and force First, for the convenience of subsequent motor principle explanations, let’s review the basic laws/laws about currents, magnetic fields, and forces. Although there is a sense of nostalgia, it is easy to forget this knowledge if you donR...Read more -
What is lidar and how does lidar work?
Introduction: The current development trend of the lidar industry is that the technology level is becoming more and more mature day by day, and localization is gradually approaching. The localization of lidar has gone through several stages. First, it was dominated by foreign companies. Later, do...Read more -
What are the characteristics of the working principle of the servo motor
Introduction: The rotor in the servo motor is a permanent magnet. The driver controls the U/V/W three-phase electricity to form an electromagnetic field, and the rotor rotates under the action of the magnetic field. At the same time, the motor encoder feeds back the signal to the drive. T...Read more -
What are the three major components of new energy vehicles? Introduction of three core technologies of new energy vehicles
Introduction: Traditional fuel vehicles have three major components, namely engine, chassis, and gearbox. Recently, new energy vehicles also have three major components. However, it is not so much the three major components as it is the three core technologies of new energy. It is differe...Read more -
Motor temperature protection and temperature measurement
Application of PTC Thermistor 1. Delay start PTC thermistor From the It characteristic curve of the PTC thermistor, it is known that the PTC thermistor takes a period of time to reach the high resistance state after the voltage is applied, and this delay characteristic is used for delayed sta...Read more -
China’s charging infrastructure
At the end of June 2022, the national motor vehicle ownership reached 406 million, including 310 million automobiles and 10.01 million new energy vehicles. With the arrival of tens of millions of new energy vehicles, the problem that restricts the development of new energy vehicles in China is in...Read more -
New energy charging pile installation method
New energy vehicles are now the first target for consumers to buy cars. The government is also relatively supportive of the development of new energy vehicles, and has issued many related policies. For example, consumers can enjoy certain subsidy policies when purchasing new energy vehicles. Amon...Read more -
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 -
