Machines with high air gap density typically face operational challenges when connected in synchronism due to several key factors. High air gap density means that the magnetic field intensity in the air gap between the stator and rotor of the machine is very high. When such machines operate in synchronism, the issues include:
1. Increased Synchronous Reactance: High air gap density contributes to increased inductance in the stator winding. This results in higher synchronous reactance, which can limit the machine’s ability to manage large currents that occur during load changes or short circuit conditions, potentially leading to stability problems.
2. Heat Generation: High magnetic field strengths in the air gap area can lead to significant heat generation. This increased heat needs to be effectively managed to prevent damage to the insulation and other components of the machine. Excessive heat can reduce the efficiency and lifespan of the machine.
3. Torque Ripple and Vibration: In synchronous machines operating with high air gap density, there is a potential for increased torque ripple. This can cause mechanical vibrations, reducing the smoothness of operation and potentially leading to mechanical wear and tear over time.
4. Harmonic Distortion: High air gap densities can lead to an increase in magnetic saturation in certain parts of the stator and rotor. This saturation can cause non-linearities in the voltage and current waveforms, leading to harmonic distortion. Such distortions can affect the performance of the machine and other connected equipment.
