Abstract: As a driving power source for an automatic door, a brushless D.C. motor is employed, and the position and the speed of a door member are determined by making use of detection pulses issued from magnetic pole position detectors which are associated with the brushless D.C. motor without providing any additional detector means separately. On the basis of the current position and the current speed of the door as determined from the detection pulses and of a programmed sequence of opening and closing operations for the door as stored in a control system, the opening and closing movements of the door member are controlled.
