3. 3 8 Monitoring Motor Temperature As previously stated the 0605 Series is designed to operate below a temperature of 176 F 80 C and within an optimal range of 122 140 F 50 60 C In many situations it is desirable to monitor the internal motor temperature to ensure that the maximum temperature rating is not exceeded and that the optimal temperature range is maintained To facilitate this the 0605 Series has a thermistor that is embedded in the motor windings The thermistor connection is provided on the Motor Feedback Connector as shown in Figure 12 The thermistor temperature signal is a logarithmic function of the output resistance The graph shown in Figure 14 illustrates the internal motor temperature verses the thermistor output resistance In the graph a temperature of 176 F 80 C corresponds to a resistance of 2000 ohms f the thermistor indicates a resistance of less than 2000 ohms then the motor should be immediately shut down before thermal damage occurs The motor also contains a thermal cutoff switch If the temperature exceeds 212 F 100 C the motor will stop running until it has cooled off This feature should not be used to control the motor temperature The thermal cutoff is designed to operate only when all other precautions have failed PUSHCORP INC 0605 Servo Motor Series Manual 16 5 0610 Thermistor Temp vs Resistance Characteristics Degrees C 0 1 100 Resistance KOhms Semitec Type 2
