  • Motor mechanism
    Patent number: 8800402
    Abstract: In one use, a motor mechanism for an electronic lock is disclosed. In one embodiment, the motor mechanism includes a split nut that travels along a threaded screw drive. When the split nut is physically limited from further travel along the screw drive, the split nut decouples and recouples with the screw drive to reduce drag on the motor and thereby reduce motor burnout. As a result, smaller, more cost effective and efficient electric motors may be utilized together with simplified electronics.
