Method for monitoring the temperature of an electromotor

A temperature monitoring method in which by means of temperature sensors arranged on the electric motor, a temperature can be measured and used for determining the winding temperature of stored motor parameters and then evaluated, in which by using a dynamic thermal motor model using the operating variables, from the at least one measured temperature value and the motor parameters, temperatures occurring in the motor such as the winding temperature which occurs at given points in the motor, can be calculated.
