Abstract :
The magnetic leakage factors of two types of brushless claw-pole alternators under no-load conditions were computed using a three-dimensional (3-D) finite element(FE) method. The FE method has a high computational accuracy, so it is appropriate for solve magnetic field of the alternators. On the basis of preprocession, solution and postprocession, the magnetic leakage factors of a conventional alternator and a hybrid excitation alternator under no-load conditions in terms of different structure parameters were computed using the per unit value. Finally the results of variation trends of magnetic leakage factors of two alternators were presented and analyzed.
