DOOR OPENING/CLOSING SYSTEM WITH DOOR OPERATED BY ELECTRIC MOTOR

摘要

A door opening/closing system comprising: an electric motor which drives opening/closing operation of a door, a detection part which detects a load torque which is applied to the electric motor while the electric motor is driving the opening/closing operation of the door, a judgment part which judges if the detected load torque exceeds a preset reference value, and a stop control part which stops the electric motor by controlling the electric motor so as to generate a drive torque in the same direction as the detected load torque when the detected load torque exceeds the reference value.
