Abstract :
A numerical model has been developed to analyze and optimize the run-time performance of a disk drive spindle motor. A field-circuit coupled time-stepping finite element method is used for the analysis of the motor optimal performances with limits of supply voltage, current and power consumption during the spin-up time of the drive. Results of investigations with one and two disks are presented
