Abstract: A method and an elevator for moving an elevator car to a landing floor in case of a predefined event related to a main electrical power supply of an elevator are disclosed. The method includes charging energy from the main electrical power supply into an external electrical energy storage prior to detecting the predefined event related to the main electrical power supply, controlling an operation of an electric motor for moving the elevator car with an electrical drive to decelerate the elevator car and to produce regenerative electrical energy, selectively utilizing said energy charged from the main electrical power supply into the external electrical energy storage and said produced regenerative electrical energy to maintain an elevator brake in deactivated state.

Abstract: A passenger/goods conveyor includes at least one transport entity connected with at least one mover, which co-acts together with at least one stator beam defining a movement trajectory for the transport entity. The at least one mover and the stator beam form a linear motor, the stator beam carrying on at least two opposite sides stator faces with stator poles which again co-act with corresponding mover counter faces including mover units facing the stator poles. The mover units are arranged successively in a running direction of the mover, whereby between the two stator faces and the corresponding mover counter faces air gaps are formed, whereby each mover unit includes electro-magnetic components configured to co-act with the stator poles to provide a propulsion force to accelerate and move the mover along the stator beam as well as an attraction force between the stator faces and counter faces to adjust both air gaps. In connection with at least one of the counter faces of the mover, at least one magnetic sensor is positioned facing the stator poles. Thus, the torque angle can always be calculated even after replacement of sensor or drive components.
