英语翻译Induction motors,as with other electrical machines,haveclearly identifiable losses associated with their rotor andstator conductors,with the alternating flux in their magneticcores and with the friction and windage losses incurredthrough the rotation of the rotor and cooling fan.Like allelectrical machines,they also have an additional power losscomponent,termed stray load loss,which has manyelemental sources and which is a reflection of the non-idealnature of a practical machine.Stray load loss is both difficult to predict analytically without the use of empiricalfactors and very difficult to measure accurately.It isevaluated indirectly usually for a particular test condition bysubtracting the determinable losses from the total machineloss.Predicting stray load loss is difficult because many ofthe sources of the loss are influenced by the manufacturingprocess to a significant degree and will therefore beinfluenced by rewinding.谢绝词霸谢绝词霸
