PROBLEM TO BE SOLVED: To suppress an increase in cost, and to open and close a door easily. SOLUTION: The elevator-door controller by direct coupling or the motor driving of constitution in its own way detects the electromotive force of a motor with door operation by manual operation, and controls motor revolution so that the door 1 is driven in the manual-operation direction according to the result of the decision of the operation direction of the door by electromotive force and control conditions beforehand recorded on a controller for the elevator-door 1. Motor rotation is controlled so that the door 1 is started at speed corresponding to working speed in the manual-operation direction according to the result of the decision of the operation direction and working speed of the door 1 by motor electromotive force detected with door operation and control conditions beforehand recorded on the controller for the elevator-door 1. A stepping-motor 5 in a rotor type using a permanent magnet is employed as the driving motor for the elevator-door 1, and the operation direction of the door 1 is judged by the order of electromotive force detected by each exciting coil of the stepping-motor 5. |
