A power operator assembly is provided for moving a sliding door between a sliding door of a motor vehicle between a closed position and an open position. The power operator assembly includes a guide rail fixedly secured to the motor vehicle and defining a rail length. A slide mechanism slidingly engages the guide rail. A drive is fixedly secured to the guide rail for selectively moving the slide mechanism along the guide rail in either direction. First and second cables each extend between the sliding door and the slide mechanism for moving the sliding door as the slide mechanism is driven along the guide rail. A compound pulley set is operatively connected to the drive and receives the first and second cables for powered movement of the sliding door a multiplied distance greater than the rail length as the slide mechanism is driven along the guide rail.

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.
