      DC motor and AC motor difference

      Hits:Updated:2017-08-23 17:08:12【Print】

      In the current industrial society, the motor is now being used more and more, but in the selection of the motor, is the use of DC motor is still communication motor? In order to help us to deal with this problem, Xiaobian and we briefly introduced DC motor and communication motor difference.
       
      DC motor using DC as a power supply is through the brush and commutator to the current into the rotor armature, so that the rotor in the stator magnetic field force and rotation. To complete the smooth and economical speed, no other equipment Of the cooperation, just change the input or excitation voltage and current can complete the speed.
       
      The communication motor is the use of communication as a power supply is the communication power into the stator winding, which in the fixed rotor air gap occurs in the rotating magnetic field, rotating magnetic field in the rotor winding induced current, and then the rotor in the stator magnetic field force Rotating. Simple structure, low production costs, protection and repair simple economy.
       
      In fact, the DC motor can also be used to drive electric drive, in detail the DC motor stator structure, if it is excitation stator, and made of silicon steel core, then the motor will be able to communicate with the electric drive. Generally said "DC motor "Refers to the commutator commutation of the carbon brush motor, this motor is high efficiency, speed open, so in the same component or size conditions, the use of its high speed characteristics to obtain several times the power of communication motor, which is widely used in On the volume and weight are very sensitive to the portable electric things.
       
      After the above description, we can see how the work of their own home is how to do this, so the more rapid selection of equipment for the motor.Through the above description, we can see what their own home is how to do work, so faster Pick the motor for the equipment.
