The linear brushless doubly-fed machine (LBDFM) as a novel type of has attracted extensive attention in recent years. Due to the complex magnetic fields and end effect, there is rich low-frequency thrust ripple LBDFM. In order make physical process clear, effect on winding magnetomotive force (MMF) studied. Firstly, shifted slot vector affected by obtained. Then, negative sequence motive analyzed with certain configuration. Finally, generation explained. analysis results are verified finite element algorithm (FEA) proposed method can be applied most machines short primary.
