A method of driving a door of an automatic door assembly by a linear motor mounted within the automatic door assembly. The method comprises the steps of driving the door by at least a normal propulsion force of the linear motor, driving the door by a propulsion force which may range from zero to nearly the normal propulsion force, and then driving the door by the normal force again thereby reducing the speed of travel of the door during its opening and closing intervals. |
