主　　题：Auxiliary slot the radial electromagnetic force the Water-filled Submersible Induction Motors 

摘      要：Aiming at the problem of electromagnetic vibration of the water-filled submersible induction motor(WSIM),a method of opening auxiliary slots on the rotor side is proposed to weaken the air-gap field harmonics caused by the rotor slot permeance *** analyzing the research status of electromagnetic vibration of the WSIM and the composition of the air-gap magnetic field of the motor,the idea that the auxiliary slots mainly affect the air-gap field harmonics by changing the air-gap permeance of the motor is put *** mathematical model of air-gap permeance of WSIM is established to simulate the influence of auxiliary slots on the air-gap *** the parametric analysis of the mathematical model,the change of auxiliary slot size is *** air-gap permeance waveform is decomposed by the two-dimensional Fourier transform,and then the variation of the air-gap permeance harmonics with the size of the auxiliary slot is ***,the finite element simulation model of the WSIM with the auxiliary slots is established,and the waveform of the air-gap flux density of the motor is analyzed to verify the effectiveness of the mathematical ***,the results show that after opening the auxiliary slot,the radial electromagnetic force of the motor was reduced by 28.4%.
