Comparison between asynchronous motors and synchronous motors

    Comparison of Asynchronous Motors and Synchronous Motors
       The difference between asynchronous motors and synchronous motors is a bit complicated to talk about. In simple terms, you can understand it as the difference in speed. The speed of an asynchronous motor changes with the change of the load, while the speed of a synchronous motor does not change. Will change. Below, the yb3 asynchronous motor manufacturer - Shanxi Jinxinrui Trading Co., Ltd. will share with you the comparison between asynchronous motors and synchronous motors:
       We can see that the speed on the nameplate of the three-phase asynchronous motor is calibrated at 2800r/min, and the power supply is 50Hz (3000r/min).
       The three-phase asynchronous motor is composed of two parts: the three-phase stator winding and the rotor. The three-phase stator winding: generates a rotating magnetic field, and the rotor: generates moving electromotive force and induced current under the action of the rotating magnetic field. The rotating magnetic field generated in the stator cuts the coil of the rotor, generating an induced electromotive force in the coil to form an induced current. The current generates a Lorentz force in the magnetic field, and the Lorentz force drives the rotor to rotate. The rotation of the rotor can never keep up with the rotation of the stator's magnetic field, because if the rotational speed is the same, the stator's magnetic field cannot cut the coils of the rotor, and no induced current can be generated.
       Faraday's electromagnetic induction theorem: I=BLVsinθ, B, L, and θ are fixed values, and the current is determined by the relative speed between the stator magnetic field and the rotor.
       Ampere force: F=BIL, B is a fixed value, L is a fixed value, and F depends on the induced current I.
       Therefore, as long as the motor is loaded, there will be a relative speed between the speed of the rotor rotation and the stator magnetic field. That is the existing speed difference. Let’s talk about synchronous motors: The difference between synchronous motors and asynchronous motors is that synchronous motors have supporting excitation equipment, that is, the current in the rotor coil is not an induced current but an external direct current. The power output of this kind of motor depends on the size of the excitation current I F = BIL.
       Synchronous motors are generally used in condensers and large special equipment, and are rarely used in civilian and industrial applications.
