A method for moving an elevator car of an elevator to evacuate passengers from the elevator car in the event of a power failure, wherein a brake blocks a vertical movement of the elevator car, includes the following steps: transmitting electrical power to the brake of the elevator to release the brake and enable the vertical movement of the elevator car, the brake being moved and held in a large number of positions, ranging between a fully closed position and a fully opened position, according to the electrical power transmitted; determining an actual speed at which the elevator car is moving; comparing the actual speed with a target speed; and adjusting, in particular increasing or reducing, according to a deviation of the actual speed from the target speed, the electrical power transmitted to the brake, so that the actual speed substantially corresponds to the target speed.
