Abstract: An asymmetrical drive motor and apparatus with the asymmetric drive motor driving a barrier. The asymmetric drive motor drives the barrier at different drive powers according to direction, time of travel, safety requirements or speed. The drive power is controlled by electrically changing the capacitance value for a permanent split capacitor motor.
