What parts does the stator of a three-phase asynchronous motor consist of?
Three-phase asynchronous motors can be divided into two types: cage type and wound rotor. Asynchronous motors, like other motors, are divided into two parts: the stator and the rotor. The stator construction of cage and wound rotor asynchronous motors is the same, only the structure of the rotor...Read more -
Motor temperature rise and temperature control techniques
For a motor, although it is not a uniform material, the basic characteristics of the heating process are generally applicable to the motor. In order to ensure that the temperature rise of the motor does not exceed a certain value, it is necessary to reduce the losses generated in the motor and in...Read more -
What is the difference between a three-phase synchronous motor and a three-phase asynchronous motor?
The difference between three-phase synchronous motor and three-phase asynchronous motor: 1. The structure is different. The rotor of a synchronous motor has windings and brushes to supply power to the rotor, while the rotor of an asynchronous motor has no windings and no brushes. 2. The principle...Read more -
The difference between the design and selection methods of general reducer and special reducer
The biggest difference between the design and selection methods of general reducers and special reducers is that the former is suitable for various industries, but the reduction can only be designed according to a specific working condition, so when selecting, users need to consider different cor...Read more -
Basic structure of three-phase asynchronous motor
The three-phase asynchronous motor consists of two basic parts: a fixed stator and a rotating rotor. The rotor is installed in the inner cavity of the stator and is supported on two end covers with the help of bearings. In order to ensure that the rotor can rotate freely within the stator, there ...Read more -

Development history and Working principle of three-phase asynchronous motors
The history of electric motors can be traced back to 1820, when Hans Christian Auster discovered the magnetic effect of current. A year later, Michael Faraday discovered electromagnetic rotation and established the first primitive DC motor. Faraday discovered electromagnetic induction in 1831, bu...Read more -
It is difficult to accurately test the welding quality of squirrel cage rotors. What are the commonly used inspection methods?
The welding quality of squirrel cage rotors (mainly welding resistance and mechanical strength) is difficult to accurately test. Generally, the inspection method used is mostly visual inspection, but it does not mean that visual inspection can find all problems. The welding quality of squirrel ca...Read more -
