Claim 8:
9. One or more controllers for a six phase electrical motor, said six phase electrical motor including a motor stator including a first stator winding arrangement and a second stator winding arrangement which is electrically independent of the first stator winding arrangement, the first stator winding arrangement and the second stator winding arrangement each comprising three combined windings; the first stator winding arrangement and the second stator winding arrangement being symmetrical and offset by an angle to each other, such that each of the three combined windings of the second stator winding arrangement has a corresponding combined winding in the first stator winding arrangement and offset thereto by an angle, wherein the one or more controllers are configured to:
a) determine a first value of currents in the three combined windings of the first stator winding arrangement and a second value of the currents in the three combined windings of the second stator winding arrangement;
b) determine a first value and a second value of torque from the first value and the second value, respectively, of the currents determined from a); and
c) control an operation of the six phase electrical motor using the first value of the torque, and using the second value of the torque for independent purposes including safety or monitoring.
