Document Type and Number:
Japanese Patent JP2008530972
Kind Code:
A
Abstract:
The method involves alternatively supplying a pulse-width modulated voltage to stator lines (U, V, W) such that the lines are repeatedly energized with alternating polarities. The electric currents resulted due to the energization of the lines are measured by a current measuring device (14) and are evaluated to determine a high measured current. An allocation of the stator lines to the axes is determined based on the high current. An independent claim is also included for a device for determining a position of a rotor of an electric machine.
