The Denso motor is used normally on Power Windows. It has thermal protection inside to keep the motor from catching the car on fire in case there is an electrical failure and the motor is stuck on drawing current.

They are not designed or intended to drawn current non-stop for long periods of time, instead they are designed to be non-backdriveable (to prevent windows to be forced open as a means of theft deterent) and to draw current for a relatively short cycle (image taking 10 minutes to open or close a window).

Also, I don't know what kind of load they are trying to move, but the less force the better - so minimizing the drag (friction) will help but it will not resolve the issue over a 10 minute time period.
