A DC gate motor has excellent starting torque (much greater than an AC motor). This high starting torque is ideal to overcome the initial friction of getting the gate moving and accelerating the gate up to speed.

The speed of a DC gate motor is easily controlled and thus a gate can be softly ramped up to speed and slowed down as required (see the D5 motor).

The DC motor is more efficient than comparable AC motors thus virtually eliminating shutdown due to over – temperature.
With a battery the gate can be operated a limited number of times in total power failure conditions (actual number of operations depends on the capacity of the battery).

In areas of no AC mains power a solar panel can be used to charge a battery. Typical applications are farming communities, or high security sites located on mountainous areas, etc.
