Abstract
A method for operating an electrical machine is used to calculate a value of a first torque which can be provided at a maximum by the electrical machine in a future interval, wherein, by limiting the torque which is provided in the interval to the value, overheating of at least one semiconductor, which is required for transmitting the electrical power, due to a power loss is prevented and/or the threat of overheating and the onset of derating is diagnosed and therefore prevented.
