摘  要：
永磁式涡流缓速器电磁场分析是其设计的核心。为了研究永磁式涡流缓速器电磁场分布,将缓速器的永磁体等效为磁化电流,从麦克斯韦方程组出发,应用Rogowski方法,研究了气隙磁场分布,计算了转子鼓中的涡流密度,推导出了永磁式涡流缓速器的制动力矩计算公式。采用Rogowski方法不仅清楚地揭示出永磁式涡流缓速器的电磁场物理本质,而且制动力矩理论计算值与缓速器台架试验结果的误差小于10%,在可接受范围内。

摘  要：
Electromagnetic field analysis for permanent magnet type eddy current retarder is the key part for designing.In order to research electromagnetic field distribution of the retarder,permanent magnet was made equivalent to a magnetized current.Flux density and eddy-current density in the air-gap and rotor of retarder were analysed and calculated respectively based on Rogowski method;meanwhile, the computation formulae of its braking torque were derived in order to reflect the relationship between braking torque and different design parameters.The analytical model was proved to be an effective model that can reveal the essence of electromagnetic field of permanent magnet type eddy current retarder,and the comparison of bench test result and computation result shows that the maximum error is less than 10%,which means Rogowski method is effective.
