The electric machine has a connector or a connection box which is used to read out in-built temperature
and rotation sensor (resolver) data from the electric machine. The temperature data comes from PT100
sensors in the stator windings and in some cases in the bearings. The rating plate has the information
about the options of the electric machine: different options add sensors, and some electric machines do
not have all the sensors. For more information about the options, refer to Chapter
