Abstract
A method of measuring torque is provided in a six phase electrical motor which includes a motor-stator including two electrically independent stator winding arrangements which each have three combined windings such that the winding arrangements are symmetrical and offset by an angle to each other and such that each combined winding of the second stator arrangement has a corresponding combined winding in the first stator arrangement and offset thereto by an angle. The method includes a) determining the current in the three combined windings of the first stator arrangement and/or the current in the three combined windings of the second stator arrangement and b) determining the torque from the currents.
