Application Notes Rexroth IndraDyn A
9.9 Motor Temperature Overview
In their standard configuration, stators of IndraDyn L motors are equipped
with built-in motor protection temperature sensors.
These have nearly a linear characteristic curve (see Fig. 9-16).
Type KTY84-130
Resistor at 25°C 577 Ohm
Resistor at 100°C 1000 Ohm
Continuous current at 100°C 2 mA
