摘 要:盘式涡流永磁调速器是一种新型调速装置,安装在电机和负载之间,通过调节导体转子与磁钢转子之间间隙大小,改变磁通密度,进而调节转矩进行调速。对其电磁场进行分析并建立转矩表达式,通过分析得到结构尺寸、关键零件材料属性、转差3个方面影响传动特性的因素。并运用Ansoft软件中的Maxwell 3D部分建立仿真模型,单独改变每一因素进行三维静态、瞬态仿真,得到气隙磁感应强度分布图及各因素对传动转矩和磁能利用情况的影响曲线,分析变化原因得出结论,为该类永磁调速器结构尺寸优化、材料选择等提供参考。The disc type eddy current permanent magnetic governor is a new type of device for speed control,it is installed between motor and load.The torque and speed can be adjusted by magnetic flux density which relates to the gap size between the magnetic steel rotor and conductor rotor.The governor electromagnetic field is analyzed and the torque expression is established.Through the analysis,the influence factor of structure size,material property of key parts,rotation speed difference three aspects affects on the transmission characteristic are got.Then,by using the Maxwell 3D of Ansoft software,the simulation model is built and the simulation of 3D static,transient is carried out by changing influence factors separately,the air gap magnetic flux density distribution diagram and curve of each influence factor on the torque and magnetic energy utilization are obtained.By analyzing the variation reason,the conclusion is got and some references for structure size optimization and material selection of this sort of permanent magnet governor is provided.
