Prediction of the static unbalanced magnetic pull in synchronous surface mounted permanent magnet machines

Prediction of the static unbalanced magnetic pull in synchronous surface mounted permanent magnet... The paper presents a calculation effort efficient analytical formula for the prediction of the static unbalanced magnetic pull (UMP) in synchronous surface mounted permanent magnet (PM) electrical machines. The derived formula predicts the UMP making use only of the magnet remanent flux density, rotor eccentricity, and geometrical parameters of the motor. The formula was discussed and compared with measurement data. Except of the UMP the eccentricity-dependent magnetic stiffness coefficient has been derived and presented in figures as a function of the ratio of the airgap length to the magnet height.

Abstract

The paper presents a calculation effort efficient analytical formula for the prediction of the static unbalanced magnetic pull (UMP) in synchronous surface mounted permanent magnet (PM) electrical machines. The derived formula predicts the UMP making use only of the magnet remanent flux density, rotor eccentricity, and geometrical parameters of the motor. The formula was discussed and compared with measurement data. Except of the UMP the eccentricity-dependent magnetic stiffness coefficient has been derived and presented in figures as a function of the ratio of the airgap length to the magnet height. It could be showed that in the case of examined PM machines, the magnetic stiffness coefficient varies quite moderate with the rotor eccentricity.
