摘要
无轴承磁通切换电机因转子结构简单、热退磁风险低等优点日益受到学界关注。以磁通切换电机无轴承运行为研究目标,在建立12/10结构磁通切换电机悬浮力模型的基础上,将直接转矩控制思想移植到无轴承磁通切换电机悬浮力控制策略中,从理论上推导直接悬浮力控制策略适用于该电机类型的可行性。最后在一台原理样机上通过实验验证直接悬浮力控制的正确性。
Due to the advantages of simple rotor structure and low risk of thermal demagnetization,bearingless flux-switching permanent motor(BFSPM)has attracted scholars′great attention.The principle of 12/10 structure BFSPM was studied.Firstly,the mathematical model of suspension force was established by FEA.Based on that,the idea of direct torque control was transplanted into the suspension force control strategy.The feasibility of direct suspension force control was proved by theoretical deduction.Finally,the validity of direct levitation force control was verified by experiments on a prototype.
