    Working characteristics of three-phase asynchronous motor ②

    3. Power factor characteristics When the output power of an asynchronous motor changes at the rated voltage and rated frequency, the change curve of the stator power factor cosφ1=f (P2) is called the power factor characteristic. Since the total impedance obtained by the equivalent circuit of the...

  • What parts does the stator of a three-phase asynchronous motor consist of?

    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...

  • What is the difference between a three-phase synchronous motor and a three-phase asynchronous motor?

    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...

  • The difference between the design and selection methods of general reducer and special reducer

    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...

  • Basic structure of three-phase asynchronous motor

    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 ...

    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...
