A 75-100 MeV H-compact cyclotron CYCIAE-100 is being constructed at China Institute of Atomic Energy(CIAE).About 200μA proton beam will be provided by CYCIAE-100.The imperfection of magnetic fields will remarkably affect the acceleration orbit and beam envelope in CYCIAE-100.The effects to the accelerating beam by the imperfection fields,especially the field components Br on the mid-plane will be analyzed in detail with tracking code COMA.Poles misalignment that causes magnetic imperfection will be described in the paper.According to the simulation results,the tolerance of the poles machining and assembly will be illustrated in this paper.
