    Abstract: A drive device of an elevator includes a frequency converter to be connected to a public AC supply network and an elevator motor. The frequency converter includes a network rectifier configured to be connected to the AC supply network, a motor bridge to be connected to the elevator motor and a DC intermediate circuit located between the network rectifier and the motor bridge. The motor bridge is controlled by a control circuit which feeds the motor bridge with control pulses to regulate the motor speed. The drive device further includes at least one drive prevention circuit connected between the control circuit and the motor bridge. The drive prevention circuit is configured to obtain a safety signal from an elevator safety circuit includes two separate safety input circuits each configured to be connected to the elevator safety circuit to receive a safety signal. Each of the safety input circuits is configured to interrupt the connection between the control circuit and the motor bridge in response to the safety signal status.

    Abstract: In a method for performing a manual drive in an elevator after mains power-off, the frequency converter of the motor is separated from mains, any safety blocking of the brake drive and/or motor drive is disabled, current is supplied from the battery to the brake drive to open the elevator brake and current is supplied from the battery to the drive control to allow regulation of the motor speed via the inverter bridge, the manual drive control observes the motor speed via the speed sensor and starts a speed feedback loop to regulate the motor speed to a manual drive reference value by feeding a three phase-AC current to the motor windings via the semiconductors of the inverter bridge, which manual drive speed reference is lower than the speed reference for normal elevator operation, when the car reaches a floor level the floor level indicator is activated, and the actuator is released whereafter the current supply from the battery to the elevator brake is interrupted and the previous disabled safety blocking of the brake drive and/or motor drive is enabled again,

    Abstract: A wireless power transfer arrangement for an elevator car of an elevator is presented. The wireless power transfer arrangement comprises primary winding units distantly arranged with respect to each other at first positions of an elevator shaft along which the elevator car is configured to be moved, at least one secondary winding unit arranged to the elevator car. Each one of the primary winding units and the at least one secondary winding unit are arranged so that there is a gap between said winding units for enabling movement of the secondary winding unit with respect to the primary winding units and for establishing an inductive coupling between said winding units whenever said winding units are arranged to face each other at one of the first positions.

    Abstract: The invention relates to a passenger conveyor, e.g. an elevator, comprising a conveyor motor being controlled by a conveyor control via a motor drive, the motor drive comprising a frequency converter with a rectifier bridge, an intermediate DC circuit and a converter bridge connected with the conveyor motor. The rectifier bridge is configured to be connected to mains via at least one relay, which relay is controlled by the conveyor control, the conveyor comprises a deep sleep mode, in which the frequency converter as well as at least a major part of conveyor control is switched off,in which conveyor the intermediate DC circuit forms the power supply for the conveyor control. During the activation of the deep sleep mode the conveyor control is configured to open the relay, whereby at least one signal circuit of the conveyor is configured to remain powered at least during the deep sleep mode. The conveyor comprises a wake-up circuit which is connected to the signal circuit and which is configured to be permanently powered at least during the deep sleep mode, which wake-up circuit is configured to close the relay dependent on a signal received from the signal circuit.
