Power Sliding Door Motor: Description and Operation
Power Sliding Door Components
The door motor is located in the center of the power sliding door and is comprised of three parts. The three parts of the door motor assembly are the
motor, gear reduction and clutch assembly. The door motor assembly provides the power and torque to move the sliding door from the open/closed
position to full closed/open position, after the power latching mechanism has released.
The door motor is replaced as a complete assembly, which includes the DC motor, gear reduction and clutch assemblies.
With the push of a power sliding door command switch, the power sliding door control module will signal the latch assembly to release the door from its
primary locked position. The door motor will then take over to provide the power to open the door to its full open or closed position. The gear reduction
portion of the motor assembly reduces the speed of the motor from 5800 to 260 rpm and also increases the torque to the lower drive unit. The clutch
portion of the motor assembly engages the motor to drive the door under power and disengages it so the door can be moved easily under manual
operation.
