Abstract
In spindle motor design and analysis, calculation of the torque and force is an essential step for the performance prediction. A method for the calculation of the Unbalanced-Magnetic-Pull (UMP) is proposed in this paper. As the method is based on the combination of the strength of analytical and numerical methods, it can yield more accurate results than traditional methods, and can be conveniently implemented in the computer aided design/analysis softwares for spindle motors
