The drive motor system

The stairlift is driven by a drive motor. This is connected via three planetary transmission stages to the drive wheel
that engages in de rail rack. The motor must deliver the required force to transport the chair in a comfortable way by
regulating the speed and acceleration of the chair along the transport rail. A brushless DC motor is used for this job.
