Overview:
To cope with the growth of three-phase asynchronous motors, our manufacturers have also tried hard and aerodynamically. In order to follow the international growth trend of motor efficiency standards and the implementation of the common national energy-saving and emission-reduction policy, my country has formulated the national standard GB 1. ..

Overview:
I talked about the drafting of the regulations of the United States on three-phase asynchronous motors. Today, I will talk about the EU’s drafting of the performance and efficiency standards for three-phase asynchronous electric motors. First, the EU divides the efficiency of motors into three levels, EFF1, EFF2, and EFF3. Among them, the EFF3 motor is...

Overview:
What is the quality of a three-phase asynchronous motor? It is mainly related to these aspects. The first is the material. If there is no good raw material, it is impossible to build a good product, so a good raw material is the quality of the motor. The key.The second is the processing technology...

Overview:
It is well known that when using variable frequency motors, insulating materials are particularly susceptible to high temperature and accelerated aging and damage.The heat resistance of different insulating materials is different, so how do their insulation grades differ? Let's look down: (1) Insulating...

Overview:
Electromagnetic brake is a commonly used additional device for braking motors, and it has two types: power-on braking and power-off braking.The power-on braking method is fast and accurate in positioning. It is used for automatic intelligent control equipment that requires precise positioning. The application has certain limitations; electromagnetic power-off braking...
