Abstract (en)

[origin: WO2007090760A2] The invention relates to a method for determining the torque (M) of an, in particular permanently excitated, electric machine (1). The torque (M) can be determined in a particularly easy and precise manner by measuring a phase voltage (U<SUB>ind</SUB>) and the speed (n ou ?) of the electric machine and calculating the torque (M) based on said values.
