This study tries to analyze the torque generated in a micro-electromagnetic clutch by using FEM. For the purpose of design change and optimization of the micro-electromagnetic clutch, the torque prediction is very important. We employ a mathematical approach of the process based on electromagnetic principle. Then real material properties are substituted in the FEM model to obtain the analytical torque. For a test, the predicted torque is compared with the experimental one to discuss the rationality of torque analysis process. The analytical result agrees well with experimental data and hence explaining the validity of the mathematical process and the FEM model.
