This paper presents core loss analysis of stator core in the permanent magnet linear synchronous generator. Usually core loss is calculated from classical Steinmetz’s equations Classical Steinmetz’s equations include the hysteresis loss and the eddy current loss. But when the magnetic flux density is over 1.0 Tesla or the frequency become high, there is a big error between the analysis results and experimental results.
For correction various models have been proposed in the Jordan’s model and Berotti’s model. Berotti referred excess loss that is related to the material thickness, cross- sectional area, conductivity and parameter which describes the material microstructure. Finally modified Steinmetz’s equation include the hysteresis loss, the eddy current loss, and excess loss. In the modified Steinmetz’s equations, hysteresis loss coefficient, eddy current loss coefficient, and excess loss coefficient are derived from steel manufacturer’s core loss data by using curve fitting method (CFM). And considering of time harmonic in the magnetic flux density. Then we separate rotating field, and alternating field. L. Ma has been reported that core loss occurring in the rotating field is much larger than alternating field.
In addition, we consider the 2-D, and 3-D end effects that causing the leakage of the magnetic flux density. Finally, linear machine’s core loss is calculated from modified Steinmetz’s equations with considering end effect.
