摘要: The present invention relates to a technique for an elevator car perform emergency operation during power failure, and in particular method controlling rescue of which can passengers by performing with electromotive force permanent magnet-type synchronous motor the system employing as lifting motor. includes: step obtaining rotating due weight difference between balance failure; charging condenser; gradually increasing rotation speed from starting time thereof predetermined matched voltage condenser at initial stage failure.
