Title:
MOTOR RESTARTING CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2015/158218
Kind Code:
A1
Abstract:
A motor restarting controller, which belongs to the technical field of industrial control. The motor restarting controller comprises a logic relay unit (10), a time relay unit (20), a standby power source unit (40) and an output relay (50). The logic relay unit controls the instant closing of an output contact of the output relay when the opening moment of a normally-open auxiliary contact of a contactor or an operation signal contact of a frequency converter is detected. If it is detected that an instant sunken amplitude of a power source voltage reaches a preset amplitude before the opening of the auxiliary contact of the contactor or the opening of the operation signal contact of the frequency converter, the time relay unit controls the opening or closing of a standby power source switch of the output relay within a preset allowed voltage loss time limit so as to control the action mode of the output contact to be instant closing and delay opening within the allowed voltage loss time limit.
