Adjustable speed motor is a kind of motor which can change the rotation speed of the engine by modifying the current and voltage to achieve high performance. Because of its good performance, adjustable speed motor has been widely used in many industrial departments. Here is a brief introduction to the common classification and application of Nanjing control special speed regulating motor?
Nanjing electric machinery_ Common classification and application of speed regulating motor:
1. Electromagnetic adjustable speed motor
It is mainly composed of single speed or multi speed squirrel cage asynchronous motor, also known as slip motor. This kind of speed regulating motor has a wide range of applications, among which the common one is used in constant torque load speed regulation and tension control. For some load comparison in the machine can play a very good buffer role, but also can play a protective effect.
2. Variable frequency adjustable speed motor
The main purpose of this kind of speed regulating motor is to change the frequency of the power input at the stator end of the asynchronous motor, so as to drive the synchronous speed. If you want to use it in the environmental protection industry, this kind of speed regulating motor is very suitable, with the advantages of mature technology and comprehensive economic index. In addition, the great advantage of variable frequency motor is no additional slip loss, has high efficiency, can play a good energy saving effect. The disadvantage is that the technology is more complex and the price is higher.
3. Variable speed motor
If it is used in some different driving circuits, it is necessary to use this type of speed regulating motor. In principle and use of the way is basically the same as other motors, mainly used in a variety of transmission machinery, such as machine tools, mining, metallurgy and other industries.
