In order to study electromagnetic oscillations resulting from slender permanent magnet rotor ec-centricity and close pole-slot number for unit combination super-thin submersible permanent magnet motor ( UCST-SPMM) , the composition and structure characteristics of UCST-SPMM were introduced, the ra-dial air gap flux density and electromagnetic force wave spectrum characteristics for UCST-SPMM with 10 poles and 12 slots were analyzed. Taking slender rotor eccentricity into account, different rotor eccentrici-ty on the influence of the electromagnetic force frequency spectrum was calculated. Prototype was devel-oped for electromagnetic noise test by the method of sound pressure. The theoretical and experimental re-sults verify the accuracy of rotor eccentricity vibration with FEM. The combination test with unit motors recommends that air gap length is greater than 0. 8mm for 114mm series motor, which provides the theory basis for the feasibility of UCST-SPMM.
