Power window motor

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

There is a direct current motor in each door which drives the power window regulators. The power windows are designed as wire lifter drives. Each power window motor has a hall effect sensor. The direction of rotation, speed and position can be determined through these. The power window motor runs at varying speeds depending on window position and switch operation.
