Overview

The Central Motor consists of an electric motor secured to the dead shaft of the door with a clamping mechanism. The motor has a gear attached to the front
of the armature. The gear drives the inside teeth of a circular crown and that rotates around the front of the motor and the dead shaft.
The motor stays fi xed to the shaft and only the crown rotates. Once the door is bolted to the crown using the required hardware, the door will wrap around the
crown. The ends of the door are supported with drums that are the same diameter as the motor crown.
When the door reaches the open and close limit switch, the brake is engaged stopping the motor.
