In this paper, the thermal field of a large scale permanent magnet embedded salient pole wind generator (PMESPWG) is investigated by using the computational fluid dynamic (CFD) modeling. To reduce the calculation, only one quarter model of the PMESPWG is established according to its symmetry. Based on the electromagnetic analysis and the empirical equations, the copper loss, stator iron loss and rotor...
In this paper, a three-dimensional (3D) eddy current field model to calculate the eddy current losses in an isolated phase bus is proposed. The temperature rises of the conductors and enclosures in the isolated phase bus are evaluated using the proposed set of thermal equations. Good agreement between the computed and test results is a good validation of the proposed methodology.
