Annotation:

The problem of torque ripple occurrence in electric drive for interior permanent magnet synchronous motor (IPMSM) is considered. Usage efficiency of standard compensation principles with energy-saving principle “maximal torque per ampere” (MMPA) utilization is analyzed. Reactionary torque ripple gain under circumstances of using of both principles is proved by the modeling results. To eliminate reactionary torque ripple gain effect a modificated compensation principle is proposed.
