摘　　要：为了研究偏心故障对圆筒型直线电动机性能的影响,基于麦克斯韦理论建立了圆筒型直线电动机偏心状态下的单边磁拉力数学模型。通过Maxwell软件对偏心状态下的电动机建模,对比了不同偏心距和偏心角下电动机电磁场和动子受力的变化。结果表明,随着偏心距的增大,动子受到的单边磁拉力线性增加,当偏心距增加至0.8时,单边磁拉力高达847.41 N;转矩随着动子倾斜偏心角增加而增加,当偏心角为0.8°时,转矩达到1.66 N·mm,但偏心角增加对动子受力影响不大。In order to study the influence of eccentric fault on the performance of the cylindrical linear motor,a mathematical model of unilateral magnetic pull force of cylindrical linear motor under eccentric condition is established by using Maxwell theory.We use Maxwell software to model the motor model under eccentric conditions,and compare the changes in the electromagnetic field and rotor force under different eccentric distances and angles.The results show that the unilateral magnetic pull force acting on the rotor increases linearly with the eccentric distance increases.When the eccentricity increases to 0.8,the unilateral electromagnetic force reaches a high of 847 N,and the torque increases with the increase of the oblique eccentricity angle of the rotor.When the eccentric angle is 0.8°,the torque reaches 1.66 N·mm,but the increase of the eccentric angle has little effect on the force on the rotor.
