Abstract

PURPOSE: To operate elevator in safe upon power failure by utilizing motor with engagement mechanism.
CONSTITUTION: It may be detected from an armature current of a cell-motor 32 that a pinion of the cell-motor has been engaged with a gear of winch 3 and torque of the cell-motor has approached to nearly zero, and when the engagement of the pinion with the gear is detected, a magnetic brake 4 for the winch 3 may be released, and when nearly zero value of torque of the cell-motor is detected, power supply for the cell-motor may be cut off. According to these constitutions, an elevator may be operated in safe and stopped at the nearest floor upon power failure.
