“…Here, in order to get the end-effect factor, the 2-d formation of (29) and (31) are calculated in two-dimensional electromagnetic field, the similar expression of ECL by 2-d electromagnetic equation can be deduced, afterwards, the total rotor eddy current losses generated by motor can be got, and the difference between it and the one of the motor section calculated by subtraction between them, is just the eddy current loss of the winding end. When 2d electromagnetic field equation is utilized, the expression of the total complex power coming into the rotor surface is listed as formula (29).…”

“…The computation of core loss and copper loss of coils has related mature method. The core loss [30][31][32][33][34][35] is calculated by loss coefficient method, while the copper loss [36][37][38][39][40][41][42][43] can be calculated by analysis method with AC effect considered. Besides, to measure the loss effectively and precisely, some improve modification of experiment has been proposed [44][45].…”

-The eddy current loss should be optimized to be as less as possible for the stability of permanent magnet in high speed permanent magnet synchronous motor (HSPMSM) rotor and ensure the high efficiency and low temperature of the motor. This paper analyzes the eddy current distribution in rotor, with consideration of the conflict of the thickness of sleeve and diameter of the rotor, calculating the eddy current loss (ECL) and the thermal distribution via Separation of variables method for solving Maxwell's equations with analytical hieratical model of ECL constructed. The optimization result of ECL of the HSPMSM whose power and rated speed is 30kw 48000r/min can be got by multi-objective optimization method, combined weighting coefficient method and traversal algorithm based on chaotic local search particle swarm optimization (CLSPSO), utilizing ECL analytical model and other analytical constraints. Related experiment and measurement has been implemented with new approach of loss separation.
