SERVOMOTOR
2.3
Temperature sensor
FXM servomotors have a thermistor as thermal protection of the servomotor
and it is located in the stator winding. Its temperature coefficient is positive
·PTC· and it is typically used in control and measurement systems. It is a
triple sensor sensitive to temperatures between 130°C/266°F and
160°C/320°F.
The following figure shows the resistance of the sensor as a function of the
ambient temperature (average values):
