To solve the problem of reduction of suspension force of permanent magnet system with variable magnetic flux path control, according to the structure of the system, suspension principle of the permanent magnet system with variable magnetic flux path control and the generation principle of the loadtorque, the influence of the mechanical structure of the system on the suspension force is analyzed by changing part of parameters of the system structure. The results show that the existence of magnetic isolation plate is the main reason for the decrease of suspension force, the permanent magnet ring can be thickened to 11.91 mm, the annular gap can be reduced to 1 mm, thickness of the “F” shaped magnetizer can be increased to 9 mm to increase the suspension force.

变磁通路径控制影响永磁系统悬架力的结构因素分析

为了解决减小磁通路径可变的永磁系统的悬架力的问题，根据系统的结构，可变磁通路径控制的永磁系统的悬架原理和负载转矩的产生原理，通过改变部分系统结构参数，分析了系统机械结构对悬架力的影响。结果表明，磁隔离板的存在是降低悬架力的主要原因，永磁环可以增厚至11.91mm，环形间隙可以减小至1mm，“ F”形充磁机的厚度可以增加到9 mm以增加悬挂力。
