Flameproof Permanent Magnet Synchronous Variable Frequency Motor for Mine

Product Description:Flameproof permanent magnet synchronous variable Frequency Motor for mine
        AC Motor is a device that transforms the electrical energy of alternating current into mechanical energy. The AC Motor is mainly composed of an electromagnet winding or stator winding for generating magnetic field and a rotating armature or rotor. The motor is made by the phenomenon that the electric coil is forced to rotate in the magnetic field. AC motors are divided into two types: synchronous alternating current motor and induction motor.
      The stator windings of three-phase AC motors are basically three coils separated by 120 degrees, which are connected by triangle or star. When three-phase current is applied, a magnetic field is generated in each coil, and the three magnetic fields are combined to form a rotating magnetic field.
     High voltage ac motors are designed with the application of modern technology resulting in compact machines featuring excellent dynamic properties, meeting the most severe application in areas that include automation and process control. 
      Besides offering reliability and high performance, which will guarantee long operating periods without requiring any maintenance, the New high voltage ac motors present outstanding operating features, which include:

     •Wide speed variation range
     •Dimensions as per GB and IEC Standards
     •High efficiency
     •Low noise level
     •High moment of inertia
     •High capacity to dynamic loads
     •Rugged construction
    •High vibration resistance
    •Excellent commutation quality

AC Motor	AC Motors can operate in high temperature, flammable and other environments, and do not need to clean the dirt of carbon brushes regularly, but it is difficult to control the speed, because it is necessary to control the frequency of AC motors (or use induction motors, increase internal resistance, reduce the motor speed at the same AC frequency. Speed, control the voltage will only affect the torque of the motor. The voltage of the general civil motor has two kinds, such as 110V and 220V, and there are 380V or 440V in industrial application.
Application	AC Motors have higher working efficiency, no smoke, odor, no pollution to the environment, and less noise. Because of its series of advantages, it is widely used in industrial and agricultural production, transportation, national defense, commercial and household appliances, medical appliances and other fields. For Example: •Compressor •Rubber mixer •Fans and Pumps •Air brower •Coal mill and rolling mill •Crushers •Conveyor belts •Centrifugal machines •Lathe •Hoist
