manufacturing of temperature sensors

One of the most important operating parameters of electric motors is the temperature of the winding. Heating occurs due to mechanical and electric processes inside the motor as well as due to ambient temperature and connected devices. If the winding temperature exceeds the maximum permissible temperature, the motor may be damaged. For this reason, temperature sensors are integrated in the winding that monitor temperature and if the maximum temperature is reached, the motor stops. However, the use of temperature sensors is not only limited to motor windings, but they are also used for bearings, temperature tracking of mechanical parts or wires, etc. Temperature sensors are protective elements which, depending on the temperature, show a predictable and accurate change in resistance that can be caused by self-heating as well as by absorbing heat from the surroundings (sensors in the winding).
