[Abstract]:Aiming at the problems related to the electromagnetic loss of the components of the high efficiency permanent magnet governor, a three-dimensional finite element analysis model of the moving eddy current field is established based on the theoretical analysis of the loss and the eddy current field theory, taking a 1 MW high efficiency permanent magnet governor as an example. The time step finite element method is used to analyze and calculate the loss of copper disk, eddy current loss of permanent magnet and the influence of steel disk on torque of 1 MW high efficiency permanent magnet governor in detail. Through the experimental analysis and finite element simulation of 1 MW high efficiency permanent magnet governor, the correctness of the analysis and calculation and the practicability of the law are verified. Finally, the effect of segmented permanent magnet on eddy current loss of permanent magnet is deeply analyzed, which provides a theoretical basis for efficiency analysis, heat dissipation design and loss optimization of permanent magnet governor.
