Method for adaptation of estimated polar wheel angle of converter fed, operated in polar wheel oriented, encoder less, non-linear, permanently excited synchronous machine, involves generating polar wheel oriented stator current components

摘要

The method involves generating the polar wheel oriented stator current components (i-d,i-q) depending on two measured stator current-actual values. The estimated polar wheel angle tracks the estimated polar wheel angle such that the calculated actuating variable is zero. An independent claim is included for a device for the execution of a polar wheel angle adaptation method.
