Embodiment Construction

[0014] The examples described in detail below are preferred embodiments of the present invention.

[0015] The embodiment shown in the drawings relates to a maglev train used as a passenger transportation system. This maglev train is equipped with a synchronous linear motor without permanent magnets in the secondary section. Such a synchronous linear motor is described in detail in German patent application DE 10 2004 045 992.4.

[0016] A compartment K of the maglev train can accommodate many people. A synchronous linear motor primary part P is respectively installed on the left and right sides of the bottom surface of the carriage. Corresponding secondary parts S are respectively fixed on a guide rail MS of a magnetic levitation train, and are respectively embedded in a dedicated space A above the primary part P of the carriage K.

[0017] The primary part P is equipped with several permanent magnets not shown in the figures. As a result, a basic magnetic flux for carryi...

Abstract

The aim of the invention is to make person conveying systems more simple and less expensive. Said aim is achieved by equipping a person conveying system with a synchronous linear motor comprising a rack-shaped, permanent magnet-less secondary part (S) for driving purposes while the primary part of the synchronous linear motor is fixed to the conveying device (K) in or on which persons can be conveyed. If the person conveying system is embodied as a magnetic levitation railway, the synchronous linear motor makes it possible to conserve a significant amount of energy as opposed to an asynchronous linear motor as the permanent magnets provide a certain basic magnetic flux that can be used for supporting the railway car and driving the same in the direction of travel.

Description

technical field [0001] The invention relates to a passenger transport system comprising a transport device in which or on which passengers are transported, and an electric motor for driving the transport device. Background technique [0002] Passenger transportation systems such as trains, elevators, and escalators are mostly driven by rotating electric motors. In some cases, it is also driven by an asynchronous linear motor. However, in the presence of an air gap, these drive methods tend to have higher energy consumption. [0003] In principle, synchronous linear motors can also be used instead of asynchronous linear motors. In this case, a rack-shaped secondary part with permanent magnets is arranged on the movement path, through which the primary part of the synchronous linear motor is moved. A problem with synchronous linear motors, however, is that the secondary part is susceptible to contamination due to ferroelectric particles adhering to those permanent magnets. ...
