IRIS Squirrel-cage motor rotor winding fault-MDSP3
Based on 50/60 hz frequency current amplitude (dB) and plus or minus 2 sf1 sideband frequency current amplitude (dB) between the average difference (dB) to assess
Average difference (less than or equal to 40 db) of said rotor winding with crack or rods fracture
Mean difference dB value is smaller, the more serious the squirrel cage winding fault, if the number of rotor bars, known to fracture the rods to more accurate estimates of the amount
基于50/60HZ频率的电流幅值(dB)以及±2Sf1边带频率的电流幅值(dB)两者间的平均差值（dB）来评估
平均差值（小于或等于40dB）的表示转子绕组有裂纹或棒条断裂
平均差dB值越小，鼠笼绕组故障越严重，如果已知转子棒条的数量，能对断裂棒条的数量进行更准确的估计
| Air-gap eccentric severity standard: based on the frequency component in the rotor slot (HRSPFC) the maximum value (dBh) and two rotating speed frequency component (fr), average value of the poor 气隙偏心严重度标准：基于转子线槽中频率分量(HRSPFC)的最大值(dBh)和二个旋转速度频率分量(fr) 平均值的差 |
基于转子线槽中频率分量(HRSPFC)的最大值(dBh)和两个边频带频率(fr)的平均值(dBl+dBu)/2的差异dBav
