The embodiment of the invention discloses an elevator rescue method, an elevator rescue device and a storage medium, and belongs to the technical field of elevator control. In the embodiment of the invention, the permanent magnet synchronous motor is controlled to enter a star sealing state when an input power supply of the permanent magnet synchronous motor is powered off, and the given initial value of the exciting current of the current loop is controlled to be gradually reduced to zero based on the two-phase rotating coordinate system current of the permanent magnet synchronous motor and the running speed of the elevator in the star sealing state; switching the permanent magnet synchronous motor from a star sealing state to a closed-loop control state; based on the current running speed of the elevator and the leveling adjustment distance of the elevator, the leveling deceleration time of the elevator is determined; in the closed-loop control state, the elevator is controlled to smoothly decelerate and stop in the leveling area based on the leveling deceleration time, and the elevator can be accurately stopped in the leveling area when the input power supply of the permanent magnet synchronous motor is powered off and elevator rescue is carried out.
