FAQ

1. How big is the motor air gap?
          A certain length of air gap should be maintained between the outer surface of the rotor of the motor and the inner surface of the stator to ensure that the rotor can rotate freely in the stator cavity. Although there is no direct electrical connection between the rotor and the stator, when the stator winding is energized, there is an electromagnetic connection between the stator and the rotor through the air gap. Energy conversion function between mechanical energy.
    
          The length of the air gap has a great influence on the performance and operation reliability of the asynchronous motor. If the air gap is too large, the reluctance will increase greatly, the excitation current required to achieve the same magnetic field strength will increase greatly, and the excitation loss will also increase greatly, the power factor of the motor will decrease significantly, and the performance of the motor will deteriorate. In order to reduce the excitation current and improve the power factor, the air gap should be minimized. However, if the air gap is too small, the harmonic magnetic field of the air gap will increase, the stray loss and noise of the motor will increase, and the maximum torque and starting torque will be reduced. On the other hand, if the air gap is too small, it is easy for the running rotor to rub against the stator, resulting in a sweeping failure, or even the stuck rotor does not rotate, which reduces the reliability of operation and brings difficulties to assembly. Generally, the air gap of small and medium asynchronous motors is about 0.25~1.5mm, and the air gap of large and medium asynchronous motors is about 0.75~2mm.
