Abstract
PURPOSE: To prevent a motor or the like from being damaged, by detecting a position slightly before the fully opening position of an electric shutter, an electric blind, or the like to avoid a rapid stop of the motor caused by a decrease in a voltage impressed to the motor. CONSTITUTION: In an opening/shutting controller for an electric shutter 1, an electric blind, an electric curtain, or the like, a means 3 for detecting the rotation number of a motor 2 is installed to detect a position Pv slightly before a fully opening position Po of the electric shutter or the like. A voltage impressed to the motor 2 is decreased at the position Po, and after the electric shutter 1 or the like is driven to the fully opening position Po while decreasing the torque, the operation is stopped at the fully opening position Po.
