Abstract
A temperature sensing assembly for a motor having an armature includes a Hall Effect sensor disposed adjacent the armature. The Hall Effect sensor senses rotation of the armature. The Hall Effect sensor includes an electrical output and generates a stepped output signal. The temperature sensing assembly also includes a thermistor connected to the electrical output in series therewith. The temperature sensing assembly also includes a pull-up resistor electrically connected to the thermistor, a voltage source and a signal output such that the stepped output signal changes depending on the temperature of the motor due to changes in the resistivity of the thermistor as is changes its resistivity as a function of temperature.
