Abstract
A thermistor circuit for sensing the temperature of an intermittent duty wound field motor is connected between the field and armature windings of the motor. When the field and armature winding currents are substantially zero (off duty), the resistance of the thermistor circuit is sampled by the motor controller, using the armature and field winding conductors.
