Abstract
A method for determining an electrical torque of an electrical machine includes determining an electrical torque in a first speed range with a first algorithm, and determining the electrical torque in a second speed range with a second algorithm which differs from the first algorithm. An upper limit of the second speed range is slightly higher than a lower limit of the first speed range. An apparatus is provided to determine the electrical torque of the electrical machine with the aforedescribed method.
