Abstract: An electric operator for a sliding door mounted for sliding movement along a track, comprising a motor having an iron cooling flywheel disposed on a drive shaft thereof, the flywheel being provided for imparting a predetermined amount of inertia for starting and stopping of the motor such that the operation of the motor is characterized by a soft start and stop. A worm gear reducer is connected to the drive shaft for effecting a predetermined reduction ratio of rotation. A limit switch is coupled to the reducer for limiting rotation of the drive shaft to a predetermined number of rotations, and apparatus is provided for coupling rotation of the drive shaft to the linear movement of the sliding door along the track.
