    摘要： An apparatus for controlling an elevator door 12 includes a three phase AC motor 26 that receives control signals from a controller 18. The signals are issued at control points along a speed versus distance profile map 24 that represents the control points as a percentage of the total distance to be travelled by the elevator door 12. The total distance of door travel in one direction is measured be counting the number of pulses generated by an incremental encoder 32 during a training run wherein the door is moved between its extreme positions at a constant speed. The number of pulses counted is then normalized to represent 100% of the distance travelled. During operation, the pulses are counted whenever the elevator door 12 is in motion and control signals are issued based upon the number of pulses counted.
