Be very careful when choosing this option. The motor will be stationary, and a stalled motor draws a lot of current. Some motors will be okay with that for a while (I think the window motor is one). Others will heat up quickly but should survive because they're massive, like the CIM minibike motor. But others will fry if they're powered for very long without spinning -- the scent of a smoking Globe motor is familiar to many.

The other options are to provide a mechanical brake or to use a gearing system that won't backdrive.
