Abstract
In spindle motor design and analysis, calculation of the torque and fo rce is an essential step for the performance prediction. A method for the calculation of the Unbalanced-Magnetic-Pull (UMP) is proposed in t his paper. As the method is based on the combination of the strength o f 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.
