摘　　要：在极化磁系统4种典型结构统一数学模型的基础上,给出了基于永磁参数的吸合力矩表达式.分析并研究了永磁回复磁导率和永磁起始工作点对永磁力矩、极化力矩、电磁力矩及吸合力矩特性的影响,所得出的结论对极化继电器产品设计具有一定的指导作用.Based on the unified mathematics model of the polarized magnetic system, the torque equations are given that can be divided to three items: permanent magnet torque, polarized torque, electromagnetic torque with the permanent magnet parameters. The influences of the permanent magnet’s reversion susceptibility and start work point on the permanent magnet torque, polarized torque, electromagnetic torque and attracting torque characteristics are investigated. The conclusions can direct the design of the polarized relay.
